Hurricane/Tropical Storm Irene one year anniversary


What a difference a year makes, Winsor Dam at dusk, Aug 28, 2012
It has been one year since the arrival of Hurricane/Tropical Storm Irene in western Massachusetts and delivered some incredible birds to the area.   I have written about that day extensively before but find it worth mentioning again on the one year anniversary.  Besides the tropical/pelagic species brought in from the storm there were a variety of shorebirds.  The list for the day is quite amazing when you look back.  Here is the eBird list submitted by Marshall Iliff for the time that he, Scott Surner and I were at Winsor Dam at Quabbin Park.  I think it does a great job of summing up the day.
Sooty Tern, Winsor Dam at Quabbin Park, Aug 28, 2011

Quabbin Reservoir--Park HQ., Hampshire, US-MA
Aug 28, 2011 9:00 AM - 8:00 PM
Protocol: Stationary
Comments: This count is for the full day totals by Marshall Iliff, Scott Surber, and Larry Therrien, joined by others in afternoon. I kept detailed hourly totals, so this count is a duplicate of the other 11 checklists. With Tropical Storm Irene hitting Manhattan at 8:00-9:00 am, and its arrival in western Massachusetts scheduled for 15:30, I arrived here at 9:00 with the intention of staying all day and trying for hurricane birds, not least of them my state Sooty Tern. All week the 'eye' had been forecast to pass over Quabbin or slightly west, so this seemed like the perfect spot being a large north-south water body near to or just east of the eye of the storm. Scott Surner arrived two hours earlier than I and stayed all day; Larry Therrien joined intermittently, including the whole afternoon. Dozens more joined from 15:00 to 18:00, and were witness to the highlights of this phenomenal day.
 
Canada Goose 90
Mallard 75
Common Loon 3 adults; one pair seen in display flight
White-tailed Tropicbird 1 ***mega; stunning, full-tailed adult spotted by Larry Therrien at 16:34 and called out as 'I got something REALLY interesting'! Larry had not acted this way all day, so I snapped to attention immediately and followed his directions, expecting a Sooty Tern. When I got on his bird in my scope, it was flying directly away over the 'gap' (the view to the northern part of the reservoir) and was flying with fast, shorebird-like wing beats. I did not instantly realize what I was looking at, and seeing the flight style and odd black stripe down the back very quickly considered and eliminated American Avocet and then Pied Avocet. The bird banked slightly about a second later and I started screaming ADULT WHITE-TAILED TRPICBIRD!, which I am sure is what Larry knew it was all along! Pandemonium ensured as the bird banked left and flew towards the island, revealing the long tail streamer flowing wave-like in the wind. On the water (probably 0.75 to 1 mile distant or so) it sat very squat, not riding high like gulls, and it propped its rear end up. Occasionally the long, slim, tail streamers could be seen while sitting, It spent almost all its time facing right towards us, into the wind, but at one point it turned sideways and a white bird with a bold black carpal bar could be seen. No one was quick enough to take photos in flight and when sitting on the water it was hard enough to keep in the scopes, let alone to photograph. It sat on the water for over an hour, drifting slowly away from us, until lost from view at about 17:40. Amazingly, one of 10 live White-tailed Tropicbirds seen, with 2 in Delaware, three in a single Cape May, NJ, seawatch, at least two live (and two dead) in New York, and one or two at Onota Lake, Pittsfield, MA. Are more are yet to come? Tom Johnson and other researchers offshore this summer noted elevated numbers of White-tailed Tropicbirds, which may be a factor in this unprecedented storm for tropicbirds. DESCRIPTION: Bonaparte's Gull sized bird with gleaming white plumage and fast, hurried flap. It was flapping constantly and seemed to require much effort to stay airborne, flying much like a Willet (I once heard a pelagic Willet called out as a tropicbird) or avocet. The wings were slender and narrow, and came to blunt points. The tail was long, as long as the body perhaps, and very slender, flowing with every flap. The upperparts had a bold black carpal bar and bold black outer primaries (outer wedge, involving several outer primaries). The back was pure white. I could not see the details of the head, but there was certainly a mask. I could not see the bill color. The bird flew left and then wheeled into a glide and flapped as it landed on the water.
Double-crested Cormorant 3
Turkey Vulture 3
Osprey 1
Cooper's Hawk 1 flying across lake; spotted by Dave Donsker
Bald Eagle 2 one ad, one TY
Red-tailed Hawk 1 my first of the day; soaring at dusk to east
Black-bellied Plover 7 *rare; one flying with Hudsonian Godwit flock at about 13:30 and at 18:00-19:00 flock of six flying with two American Golden-Plovers; in flight, blackish underparts and white rumps and tails easily seen, as well as larger size relative to the Golden-Plovers
Whimbrel 1 **rare; heard clearly 4x giving 'slightly descending 'kek-kek-kek-kek'. I must admit, I first thought it might be a flicker (an ID problem I have never had before), but after another two calls it became clear that it was a Whimbrel and I called it out to the others. We heard it give one more call then, and after that it must have circled because a minute later we heard the call again, loud, right overhead. Never seen.
Hudsonian Godwit 12 **rare; about 10:30; I initially counted 11 in the field but photos clearly show 12
Ruddy Turnstone 4 *rare; flock spotted flying south towards us into wind (and ultimately over the dam and off to the south) by Mike Resch, who commented on their dark chests and instantly agreed when I suggested turnstone (before seeing the birds); flock flew past and seen well in flight. Bold pattern of white and black on wings with white oval up central lower back and dark smudges on chest.
Baird's Sandpiper 1 *rare; flying with Ruddy Turnstones and only slightly smaller and without the chety appearance of Pectoral. Not seen well, but the size in comparison to turnstone, lack of a bold wingstripe or white rump, and long-winged appearance all combine to eliminate all species except Baird's, Buff-breasted, and Pectoral, and I was ocnfident that the shape was not that of Pectoral. The bill and head were seen well enough to eliminate Buff-breasted
peep sp. 1 small peep, probably Least
large shorebird sp. 20 one tight flock of about 20 shorebirds at 13:30 was spotted late and mostly got past us before we could Id then; some observers that saw them best thought Black-bellied Plover, but I felt I saw then well and saw long trailing legs
Bonaparte's Gull 5 at about 17:10; four distant birds and one much closer juvenile that landed on water and which I carefully checked for other gull species
Ring-billed Gull 58 almost all apparently adults
Herring Gull 24 one juvenile, one second-summer, the rest adults
Great Black-backed Gull 1 near adult; 15:00 hour; flew right over dam
Sooty Tern 1 ***mega; arrived at about 16:42; some photos by me may be identifiable and others (including Scott Surner) were shooting too; fully expected in this Tropical Storm, and by this time we had heard about Sooty Terns all around us: Boston, Long Island Sound, Manhattan, Pennsylvania, Maryland, etc. This bird flew by close (0.5 mi away or so), and generated some chatter as I screamed ADULT SOOTY TERN! A few people were struggling to get on it, but ultimately all present (10+ people) had prolonged views as this bird worked its way to the east side of the dam, fed in the small cove for 5-10 minutes, and then circled high and flew out over the dam and away (into the wind) to the south. DESCRIPTION: Moderately large tern, larger than a Common Tern with a broad-winged appearance but sharply pointed wingtips. It soared several times for 10-20 seconds and when feeding would swoop down to the water and pick things from the surface much like a Black Tern might. No molting flight feathers or aps in the plumage, so otherwise very crisp looking.  Underparts pure white. Underwings white with extensively dark undersides to primaries and secondaries, giving distinct two-toned appearance (like Swainson's Hawk). White underparts sharply demarcated from dark upperparts. Upperparts blackish with a faint hint of brownish on the central back indicating wear. Dark cap and nape connected to back without any sign of a collar, eliminating Bridled Tern. No contrast between black cap and blackish back. White forehead large and prominent in from of eyes and suqared off at rear, not coming to a point over the eye as on Bridled Tern. Tail, when flared and seen from above, had only a single narrow white rectrix, also eliminating Bridled Tern which has 2-3. Tail came to a moderate fork, with a rounded central notch. State bird for me!
Black Tern 3 *rare; 16:10 or so; Mike Resch spotted these distantly; I concurred with his ID: smallish terns that appeared pale gray overall at a distance without the white gleam of Sterna terns or contrast of a tropical tern. All even above (no white tail). I only saw the flying and did not see any foraging.
Common Tern 2 adults at 13:45 and 9:58
Sterna sp. 2 very distant, presumed Common Tern
Parasitic Jaeger 1 **rare; continuing bird from 13:00-14:00 period; adult or near adult intermediate morph; clearly not a Pomarine Jaeger, this bird was dark smoky gray on the head and chest, with a contrasting dark cap. Although I could not see a pale forehead, this plumage is probably only shown by Parasitic, since Pomarines are so dark as to have little contrast and have a more jagged cap margin and more uneven (less smooth) breastband etc. When in flight the upperwings looked very dark and the tail seemed to have some short, ragged points as though a non-adult. Some white at base of tail. In flight I felt size and structure was consistent with arasitic as well, and while I considered Long-tailed more likely here on this date, I saw nothing to indicate that species and felt the size was clearly that of Parasitic.
jaeger sp. 1 extremely distant darkish birds that were seemingly the same size. One showed dark plumage, a paler belly, and a bit of an underwing flash. I did not know if these were the same or different from the bird seen earlier, but I assume one of them was the same individual. The distance was extreme and we were unable to stay on them when flying against dark pines in the background.
Common Nighthawk 8
Chimney Swift 5
Belted Kingfisher 1
Northern Flicker (Yellow-shafted) 1
Blue Jay 2
American Crow 8
Common Raven 2
Tree Swallow 31
Bank Swallow 4
Barn Swallow 24
Cliff Swallow 2
swallow sp. 10
Tufted Titmouse 1
Cedar Waxwing 1
Chipping Sparrow 2
Northern Cardinal 1
Bobolink 4 flight calls heard
American Goldfinch 1

I managed to add two life birds, four state birds and seven birds to my Hampshire county list.   In addition to the birds the day of the storm a few days later (September 1st) I also sighted a large swift species (moving with nighthawks) that very well may have been a Black Swift. 

Here is a link from the day after the storm:

Hurricane Isaac projected path as of the evening of Aug 28, 2012
 
On the date of the one year anniversary of Irene a hurricane looks to be on track to impact the gulf coast over the next few days.  Hurricane Isaac is expected to strengthen before landfall as a category 1 storm.  Although there is likely to be no impact at all from the latest storm here I have included a link from eBird regarding the possible species that could be displaced by the storm along the gulf coast:

The tropics begin to come alive


Images courtesy of the National Hurricane Center, Aug 3, 2012
As we endure yet another heat wave (five so far this year) the tropics have also started to heat up a bit.  After a flurry of early season storms the tropics had been quiet.  This seems to be changing a bit as we start into the peak time for tropical systems.  As of today, August 3, there is a single named storm in the Atlantic as well as a couple areas of potential development.  Tropical Storm Ernesto is heading northwestward and is expected to slowly strengthen as it gets into areas more conductive for development.  As of now the forecast track takes the storm past Jamaica, past the Yucatan and then into the Gulf of Mexico.  As with most forecast tracks with tropical system, the future location of Ernesto is subject to change drastically.  The other two areas of concern include a low probability of development over the northern Bahamas and a tropical wave near the Cape Verde Islands with a moderate risk of development over the next 48 hours.  I will update from time to time as the hurricane season progresses, especially if there is potential for impact in the area.  As I have mentioned in several previous posts, tropical systems can bring some very unusual birds inland given the right conditions.  Species such as White-tailed Tropicbird, Parasitic Jaeger, Sooty Tern, an unidentified large swift species and numerous unusual shorebirds and other species arrived with Irene last August so there is no telling what species can show up during and after a tropical storm.  Here are a few links from the blog regarding the birds associated with Hurricane Irene last year.

In addition to the tropical activity I had a Louisiana Waterthrush singing at home this morning.  I have had one singing first thing in the morning on and off for the last week or two.  I also made a trip over to Quabbin and Covey WMA this evening trying for Whip-poor-wills but only got a lot of mosquito's!  One bonus was seeing a very bright meteor streak across the sky...likely part of the Perseid meteor shower.

Hurricane Irene and swifts -with a look at the possibility of displacement of Caribbean Black Swifts

As the upcoming report of the Massachusetts Avian records Committee (MARC) should be coming out in a month or so I thought I would delve into greater detail on one of the reports I submitted this year.  I will review my other submissions after the latest report comes out but wanted to take this time before the report is issued to look at my report of a large swift species seen following Hurricane Irene.  I will look at the various reports of large swift species seen during and after Irene as well as a few other reports related to other storms.  I will look at the possibility of these large swift species being the Caribbean subspecies of Black Swift (Cypseloides niger niger). 
I submitted my report to MARC as a large swift species which was seen on August 29, a day after the passage of Irene.  I cannot say with certainty what species of swift it was beyond it was not a Chimney Swift and given the hurricane and other reports of large swift species it is possible (perhaps probable) it was a Black Swift from the Caribbean population that was displaced by Irene.  The eBird Hurricane Irene wrap up summed up these swift reports nicely:
·         A large swift, now believed to be Black Swift (very likely of the Caribbean population, which may represent a species distinct from western North American ones), was seen and photographed at Cape May. Most agree it was not a European Apus swift (e.g., Common Swift), so whatever it is, it will represent a new record for the East Coast (the nearest Black Swift is from Point Pelee, ON). See Tony Leukering's report.
·         Large swifts or suspected large swifts were reported from three other locations, but not conclusively documented. These were seen off Manhattan 28 Aug; at Charleston, SC, 30 Aug (two birds); and in western Massachusetts, moving south with nighthawks (!), on 29 Aug. It seems possible, if not likely, that a decent number of Caribbean Black Swifts were displaced by this storm!

A bit of additional information regarding the possibility of Black Swifts of the Caribbean subspecies being displaced by Irene is in order at this time.  As mentioned in the eBird wrap up of the storm there was a minimum of four separate locations that reported either a possible Black Swift or a large swift species with only one of those documented with photographs (an additional sighting following TS Lee is included also).   The locations and dates of sightings followed the path of the storm and will be detailed here. 

Aug 28                Cape May, NJ                1
Aug 28                Manhattan, NY               1
Aug 29                Belchertown, MA            1
Aug 30                Charleston, SC               2
Using eBird I researched these sightings more in depth and found the following information.  As far as the Cape May sighting is concerned here is the eBird list report submitted by several people viewing in Cape May, NJ (specifically Cape Island-Sunset Beach).  The report from eBird shows the following observers present including David La Puma, Glen Davis, Louise Zemaitis, Michael Fritz, Michael O'Brien, Samuel Paul Galick, Tom Johnson, Tony Leukering.  Here is the eBird report of the sighting of this individual:
1
large swift sp.
Pix at flickr.com/photos/bonxie88; Around 2:24 pm, I was standing in the parking lot in front of the Sunset Grille when I noticed a dark, long- and narrow-winged bird north of the gift shop across the parking lot from the Grille that I first thought was a small falcon. However, I quickly realized that it was a SWIFT. Wow, a two-swift day! I turned and shouted for everyone to "GET ON THIS BIRD!" This big, apparently-all-dark swift with very long wings that were pinched in at the base, an attenuated rear end, and a flaring and notched tail exhibited wing beats that were quite slow and deep for a swift as it was drifted north away from us by the wind. Our collective opinion was that the bird was probably either a White-collared Swift (Streptoprocne zonaris) or a member of one of the species of Old World swift in the genus Apus. Alpine Swift (Apus melba) has occurred on Bermuda, so that was in the mix, but that species sports a bright white throat and belly. Though none of us had experience with Old World swifts, most Apus have more-deeply notched tails than exhibited by the Sunset Beach swift. Those of us with Middle American experience all considered that the bird was not inconsistent with an identification of White-collared Swift, a species with a few ABA-area records, including one from the northern Lower Peninsula of Michigan. Tom Johnson obtained a number of semi-reasonable pictures of the bird that we have sent off to various experts for their thoughts. The pictures prove that the bird was not an adult White-collared Swift, but the white on juveniles is restricted to the nape. Personally, until I hear otherwise, I consider the bird to most likely be referable to White-collared Swift. Should that ID be correct and should the New Jersey Bird Records Committee accept the record, it would be a first for the state and for the northeastern United States. ADDENDUM: various reviewers (including Steve Howell, Marshall Iliff, and Brian Sullivan all question the tentative ID and, though none are willing to ID specifically, question whether Black Swift is ruled out by pix.

The only photographs of any of these large swift species were taken by Tom Johnson at Cape May and can be found at the following link. 
The second sighting was from Charleston, SC (specifically Eastwood, James Island on the south side of Charleston Harbor).  There were two large swift species noted from that location in the company of Chimney Swifts.  Here is the eBird report of that sighting submitted by Dennis Forsythe:
2
large swift sp.
At Sunrise Park at harbor.2 all dark, large swifts with Chimney Swift, much larger than
Chimney Swifts, "cigar butt" shape, and a uniform all black, flew NW with Chimney Swifts out of sight.. Wings did a slight flutter when flapping. Viewed for less than 1 min with 10.5x40 bino in good light.Thanks for the reply. After reviewing my notes and memory, I would feel more comfortable with changing the sighting to "large swift sp" The birds were seen about 8AM EDT, with good light. While the color was a uniform black seen as they flew left with the sun to the right, I only saw the front for a split second and had more time ca. 30sec look after the birds flew past and had the best views when they were flying away. I did not notice a white color but I only had a brief view so I could have missed that. The birds seems a uniform black on top and bottom w/o any noticeable color differences. And I did not notice any fork in the tail as it was closed the whole time. They flew "purposefully" away from me with shallow strokes and a slight "flutter" in the outer 1/3 of the wings once or twice.with sickle shaped all dark wings. I am not confident to add any additional details w/o additional notes or memories of the sighting. Let me know what to do with these sighting. I think these were Caribbean race Black Swifts cf. Cape May, NJ record during Hurricane Irene.

The sighting from Manhattan I could not find further information on at this point.
The final sighting of a large swift species either during or immediately after Irene comes from myself and occurred at Herman Covey WMA in Belchertown, MA.  Here is my eBird report of the sighting:
1
large swift sp.
I was standing at the edge of a marsh area and had a group of Common Nighthawks moving from north to south at 9:40am. I would estimate them at a few hundred feet. After snapping a few photos of the lead birds I put the camera down and noticed three more birds appear. Two were nighthawks but the other immediately struck me as odd. It had the typical swift shape but the bird was quite bulky and I would estimate the size as about 1/2 to 2/3 that of the nighthawks. The tail was longer than a Chimney Swift and the wings were much bulkier. I got no color beyond dark overall. The wing beats to me were slower than a Chimney Swift and then it was in a glide as it went over top of me. The bird was in view for only a few seconds and then it disappeared behind trees. It did fly directly overhead of me. I was unable to get the camera up quick enough. I hobbled out to a more open area beyond the tree line but I could not relocate it. I really do not know what to make of the bird beyond it being a different swift. I looked for the bird for the rest of my time there but had no luck.

I have included my submitted report to MARC regarding this bird.  As I have had no prior experience with Black Swifts I cannot say for sure that was the species and I felt uneasy at the time as submitting it as anything other than a large swift species.  As I have stated previously I can be 100% certain the bird I saw was not a Chimney Swift and was not a swift species I was familiar with.   Following the submission of my report I was able to view White-collared Swifts in Costa Rica and the swift I saw was smaller than these swifts but certainly different in size and behavior to a Chimney Swift.  Here is my report submitted to MARC.

Rare Bird Report

Species:  Large swift species                                        Sex: unknown                                                   Age: unknown

Date of initial sighting: 9/1/2011

Time of initial sighting: 9:40am                                               

Date and Time of additional sightings:  N/A

Location: Herman Covey WMA, Belchertown, MA

Discovery info:  Bird seen flying with Common Nighthawks

Other observers: None

Complete narrative: 

I was standing at the edge of a marsh area and had a group of Common Nighthawks moving from north to south at 9:40am. I would estimate them at a few hundred feet. After snapping a few photos of the lead birds I put the camera down and noticed three more birds appear. Two were nighthawks but the other immediately struck me as odd. It had typical swift shape but the bird was quite bulky and I would estimate the size as about 1/2 to 2/3 that of the nighthawks. The tail was somewhat broad and was neither forked nor tapered. The tail did seem to me to be a little longer than Chimney Swifts would be in relation to the body. The wings were bulkier and the bird overall was just more solid looking. I got no color beyond dark overall. The wing beats were slower than a Chimney Swift and did not seem as deep.  The bird was in a glide as it went over top of me. The bird was in view for only a few seconds (approx 5 seconds) and then it disappeared behind trees.  I was unable to get the camera up quick enough to get a photo. I moved about 75 feet to a more open area beyond the tree line but I was unable to relocate it.  I continued to look for the bird following the initial sighting but had no luck.  I believe Black Swift comes the closest to matching the bird I was but I cannot say for certain.  Given the hurricane that had moved through on Aug 28 the possibilities are many.

Nearby species: It was moving with a group of Common Nighthawks as well as at least one Chimney Swift.  There were also Tree Swallows in the general area.

Vocalizations: None

Habitat and behavior:  seen over marshy area moving north to south moving with Common Nighthawks.

Other species considered and reasons for eliminating them:

As I’m not sure what the bird was I cannot eliminate several possible species.  I considered several swift species such as White collared Swift but the tail was not right and the color was dark overall.    Common Swift also does not match the bird in overall shape.  Black Swift is certainly a good candidate as it matches several attributes of my bird but I cannot be certain.

I wish I would have gotten a longer look at the swift I saw and managed a photo but it all happened so fast and I was unable to get any photos.  It will likely be one of the best birds I ever came across while birding in western Massachusetts that I was unable to conclusively identify. 
A further report of large swift species around the time of Irene comes from Derek Aldrich at Reedy River Falls Park, Greenville County, SC on September 7, 2011 following the passage of the remnants of Tropical Storm Lee. Here is Derek Aldrich’s eBird report:

2
large swift sp.
Seen during the remnants of Lee passing through. Both were larger than the nearby swifts with similar structure. I had no binoculars or camera and they were gone back in the clouds not to be seen again. The first thing to stick out was their size.

2011 hurricane season tracks (Lee-yellow and Irene-red)
I have included a map of the course taken by Lee as well as tropical storms for a few weeks previous that may have had an impact on the sightings of the large swift species.  The course of Lee does not lend itself to displacement of Black Swifts from the Caribbean.  However given the proximity in dates of Irene and Lee perhaps the large swift species seen here were indeed holdovers from Irene displacement and only discovered by coincidence after the passage of the remnants of Lee.  Again determining the exact species of this large swift species is difficult if not impossible at this point but there is at least a strong possibility that these two birds could also have been Black Swifts.
Black Swift is noted as a common breeder on various islands in the northern Caribbean including several islands that were impacted by Irene.  As this species is noted as highly aerial and migratory they are certainly a species that could be displaced by a strong hurricane and seems likely that at least several large swifts, likely Black Swifts, were displaced by Irene.  According to worldbirdinfo.net the typical departure dates for Black Swifts from Puerto Rico is between August 16-September 5 which would correspond with the dates of Irene and would lend to the maximum number of available birds available for displacement as it right at the end of breeding season. The question now becomes can the specific species be determined to any great confidence?  There are several other large swift species that could be possible but Black Swift seems the most likely candidate. 

Hurricane Irene track with strength

Although there are few hurricanes/tropical storms that have taken the exact route of Irene and impacted the east coast as heavily, there have been many storms taking the same route as Irene in the Caribbean and then impacting further south then Irene did but where there are other documented reports of large dark swifts.  As I searched through the other bird records committee’s of the various states with reports of large dark swifts following other hurricanes the following info came to light.
There are at least two more state reports of large swift species in Massachusetts with one seen following the passage of Hurricane Bertha.  As mentioned in the post below there is also a report from Florida (Dry Tortugas) of a sighting in the eye of a hurricane of several large swift species that may also have been Caribbean Black Swifts.  The hurricane in Florida that led to this sighting was Hurricane Inez that formed in late September and tracked through Greater Antilles then south of Puerto Rico through the southern side of Haiti, then Cuba and finally Florida.   The storm passed over the Dry Tortugas in early October.  Below is the route map of Hurricane Inez.

Here is the report from “Field Notes” from 1996 relating to the swift species seen in Massachusetts related to Hurricane Bertha.
Field Notes, Winter 1996, Vol 50, Number 5 by Wayne R Petersen

The  most unusual and problematic report of the season was of a large, dark, forked-tailed swift seen and photographed at Cape Pogue, C Chappaquiddick I., M.V., July 14 (G.Daniels, A. Keith, V. Laux, P. Nden et al.). Discovered the morning after the passage of hurricane Bertha, a storm whose track included the Greater Antilles, the bird apparently showed many of the characteristics of a Black Swift, a polytypic Cypseloide species that maintains a Caribbean subspecies (C. n. niger}.  Based upon body and wing shape, tail configuration, an apparently dark throat, and at least one observer's impression of white frosting on the forehead, some observers were convinced that the swift could only be a Black Swift, most probably of Caribbean origin. Perhaps not surprisingly a 1966 sight report of several large, dark swifts seen in the eye of a hurricane over Florida's Dry Tortugas was also thought to pertain to C. n. niger (Robertson & Woolfenden1, 992, Florida Bird Species).  Observers  watching the Massachusetts swift later the same day, however failed to note white about the forehead and lores and had the impression that the bird's shape, proportions and behavior were more like those of a swift in the genus Apus, possibly A . apus,  the wide-ranging Com.Swift of the Old World, for which there is an accepted Alaskan vagrant record and a questionable sight record from Barbados (A.O.U. Checklist, 1983). Based upon the difficulty of distinguishing certain large swift species, especially in this case the Caribbean race of the Black Swift, as well as the disparity in the impressions of the various experienced observers who saw the M.V. bird, at the moment the report is most conservatively categorized as "a large swift, almost certainly belonging to the genus Cypseloides or Apus" Detailed original notes and photos of the swift are being circulated among a number of authorities, whose collective knowledge will hopefully shed further light on the correct identification of this remarkable vagrant. In any event, the M.A.R.C. really has its work cut out on this one!

The MARC has reviewed the above report on a few occasions with the first review in report #4 (Feb 2000).  The report was accepted as follows:
Large, fork-tailed swift, #96-21, Chappaquiddick Is. (Dukes), 14 July, 1996 (A. Keith, G. Daniels, et al), This intriguing bird was seen by a number of experienced birders, yet there was no consensus as to species. The original observers identified it as a Black Swift (Cypseloides niger) of the West Indian subspecies, but later observers believed it to be an apus swift, most probably Common Swift (Apus apus). Photos were taken, but the Committee felt there was not enough resolution in the photographs to make a clear identification. This record remains frustrating, since whatever species was involved, it was clearly new to Massachusetts
The MARC reviewed the same report in a subsequent report and made the following observations:
Apus species, #96-21R, July 14, 1996, Chappaquiddick (Dukes), resubmitted by W. Petersen. (Third ballot. 8-1). This controversial record involved a large swift seen and photographed at the lighthouse on Chappaquiddick Island in the wake of Hurricane Bertha. The bird was originally accepted as a “Large, fork-tailed swift species” (see Report Four), but further analysis of the photographs revealed a tail shape that eight Committee members believed could only be that of an Apus swift. Common Swift (Apus apus) has been recorded from St. Pierre et Miquelon and quite likely was represented by this record; however, the Committee could not rule out Pallid Swift (Apus pallidus).

In the end the report from July 1996 will likely never be conclusively identified beyond a large species of swift. 
Here is the route map for Hurricane Bertha:

The tracks of Hurricane Inez (category 4), Bertha (category 3) and Irene (category 3) were all very similar in that they tracked through the breeding area of Black Swifts and likely displaced these birds.  I have included tracks of these three hurricanes for comparison.  All three of these hurricanes were major hurricanes with Inez reaching category 4 status and Bertha and Irene both peaking at category 3 storms.   Typically displacement of birds occurs more readily with more severe storms and all three of these storms reached ‘major’ hurricane status (category 3 or above).  Although these three storms all produced reports of large swift species there are other storms with similar tracks that did not produce reports of unidentified swifts…why?  There are probably a variety of reasons.  Some of the storms on similar tracks were even more powerful and created such devastation birders were not able to get out to the same degree as in less destructive storms.  There are more birders out and about looking before, during and after storms than ever before and they are more connected now with cell phones, internet, etc.  Perhaps some of these swift reports were overlooked as identification of various swift species can be quite difficult even under adequate viewing conditions.


There certainly is a history of swifts being blown off course by hurricanes.  One great (but sad) example can be found at the following link:   http://iles-et-ailes.pagesperso-orange.fr/2005/Martinets1.htm  , http://iles-et-ailes.pagesperso-orange.fr/2005/Martinets4.htm and    http://iles-et-ailes.pagesperso-orange.fr/2005/Martinets2.htm  The text is French but the photos speak volumes.  The photos certainly illustrate the potential for swifts to be displaced by hurricanes.  The article mentions the arrival of hundreds of Chimney Swifts blown to the isles of Saint-Pierre et Miquelon off the Canadian coast as well as to Nova Scotia and other areas of Canada following Hurricane Wilma in late October and November of 2005.  The storm formed in the Gulf of Mexico travelled across Florida and then off the east coast before landfall in Canada.  These swifts were likely transported a long distance by Wilma before being dumped out by the storm along the Atlantic provinces of Canada.

Given all this information can an accurate conclusion be reached regarding these birds?  Perhaps but we cannot be certain of the exact species of these various sightings.  Swifts can be difficult birds to identify even in good light and if you have time to study them but many of these sightings occurred in less than ideal conditions and were short in duration.  The circumstantial evidence is certainly there pointing toward the identification of these swifts being Black Swift of the Caribbean subspecies.  It will be interesting to see how the various state bird record committees handle these reports.  Certainly better photographic documentation would help but in the latest storm only a handful of photo were obtained of one of the birds so the committees will have to rely on the written description of the birds in question.  I would certainly love to have one of the only records of Black Swifts in the eastern US but I’m not entirely certain we will ever be able to determine the exact id of the bird with any true confidence. 


If anyone has any comments, questions, additional information or other observations please feel free to leave it below.
I would like to thank the creators of eBird for providing the ability to research these various reports.  I would also like to acknowledge the information I found on the MARC website, the SORA website, Weather Underground website, The Weather Channel website, and other sources mentioned within the article.

End of year wrap up

Roadside Hawk, Rio Magnolia Lodge, Costa Rica
As the end of the year rapidly approaches I will take some time to review the highlights of the year of 2011.  The total number of birds seen this year topped out at 583 with a total of 449 of those seen in the United States and the rest in Costa Rica.  I added 152 life birds with 121 of those coming from Costa Rica.  Overall my most productive year to date.

I took a total of six trips out of the area this year, which was a new high for me.  The trips included the following:  Florida in January, Arizona in April, Ohio in May, California in September, Texas in November and Costa Rica in December.  Each of these trips had their own set of highlights.
Pied-billed Grebe, Green Cay Wetlands, FL

Black-bellied Plover, Sanibel Island, FL

Eastern Screech Owl, J.N. Darling NWR, FL
Florida Scrub Jay, Canaveral National Seashore, FL
The trip to Florida was a nice getaway from the cold winter up north.  We spent a little time on the Atlantic coast near Boynton Beach and then made a trip over to the gulf coast to Sanibel Island and then up to the Orlando area.
Verdin, Saguaro NP, AZ

Pyrrhuloxia, Tucson, AZ

Broad-billed Hummingbird, Madera Canyon, AZ

Hepatic Tanager, Madera Canyon, AZ
The Arizona trip was another nice late winter/early spring getaway that provided many noteworthy birds.  I visited Mount Lemmon, Sweetwater Wetlands, Saguaro NP (both units) as well as spending a few days in Madera Canyon.  The weather was just perfect with only one day with any bad weather and that was the day we arrived in the rain.  Otherwise it was sunny and warm during the day and clear and cool at night.
American Redstart, Magee Marsh, OH

Black-throated Green Warbler, Magee Marsh, OH

Prothonotary Warbler, Magee Marsh, OH

Blackpoll Warbler, Magee Marsh, OH

Blackburnian Warbler, Magee Marsh, OH
I then took a solo trip out to Ohio to visit the area around Magee Marsh along the shoreline of the great lakes where many neotropical migrants stack up during migration before continuing their trip north across the lake.  Many species of warblers, vireos, thrushes, orioles, etc can be seen at nearly arms length as they feed along the boardwalk.  It was once again a dream for photography.  On one rainy day I decided to make the long drive up into Michigan to get to sunnier weather and see Kirtland’s Warblers on their breeding grounds. 
Western Scrub Jay, Point Reyes, CA

Black-footed Albatross, Monterey Bay, CA
Our trip to California added quite a few species to my list for the year as well as several new species to my life list.  We stayed a few days around Point Reyes and then down to Monterey to take an all day pelagic trip and then down to Big Sur.  A truly beautiful area.
Green Jay, Bentsen-Rio Grande Valley SP, TX

Green Kingfisher, Santa Ana NWR, TX
I took a second solo trip for the year when I went down to south Texas along the Rio Grande.  A little warm up to tropical birding before our trip down to Costa Rica.  It was nice to get back down there again and see the varied selection of both birds and butterflies.
Speckled Tanager, Rio Magnolia Lodge, Costa Rica

Rufous-tailed Hummingbird, Hacienda Baru, Costa Rica
Blue Dacnis, Hacienda Baru, Costa Rica

Silver Throated Tanager, Rio Magnolia Lodge, Costa Rica
The final out of area trip was down to Costa Rica which turned out to be the best trip of the year.  We were a bit apprehensive of going down but we were so glad we did.  The birds, the lodging, the food, and the weather were just great.  It was one of the best trips I have ever had with little to no stress and lots of relaxation.  Our only regret is not staying longer!
Sooty Tern (cropped, distant shot), Quabbin Park during Hurricane Irene
As far as in the local area there were several highlights with one of the most memorable birding days being the day Hurricane/Tropical Storm Irene struck the area on August 28th bringing with it a lot of rain and a lot of storm driven birds.  I will recount a bit of that day.  I made several morning trips over to Winsor Dam at Quabbin and the rain and wind made viewing difficult to downright impossible.  From mid morning on Marshal Iliff arrived and kept a vigil throughout the day as did Scott Surner a little later in the morning.  I finally made another trip over and stayed as the storm made its way to the west of us.   The first  bird of note was a calling Whimbrel that we attempted to locate along the dam without any luck.  We were pulled away from this search by Marshall who spotted a Parasictic Jaeger.  This turned out to be the beginning of a parade of unusual birds.  We spotted a group of Hudsonian Godwits as well as Black bellied and American Golden Plovers as they moved south passing over the dam.  The biggest thrill was when I spotted a white bird coming over the hill at Quabbin Park which banked revealing its ID…White tailed Tropicbird.  I immediately said “I think I have something interesting” and got others on it.  It was amazing to see a tropical pelagic bird normally found hundreds of miles away flying over and then landing on Quabbin.  The birds continued fast and furious with a Sooty Tern feeding just off the dam, another jaeger, Black Terns, Ruddy Turnstones with a Pectoral Sandpiper in tow.  One of my most memorable days of birding ever.  My only regret was not staying a little longer to see the Leach’s Storm Petrel that moved south passing over the dam.  Marshall's eBird checklist for the day is worth a look if you want a true feeling for the spectacular nature of the day: http://ebird.org/ebird/view/checklist?subID=S8749439
A few days after Irene I had one of my other great sightings of the year but one that was frustrating as well as I got such a brief look at the bird and was not able to get the camera up quick enough to document what was probably another mega bird.  I was at Covey WMA in the morning and was near a small swamp and noticed a few nighthawks moving south.  With the last nighthawks I noticed a large swift moving with them.  It was much larger than a chimney swift in the same general vicinity.  I got a brief look at it and was unable to refind the bird.  It may very well have been a Black Swift from the caribbean that was displaced by the hurricane as there were several other records along the east coast of either Black Swifts or unidentifed large swift species during and immediately after the storm.  Certainly the bird that got away from me this year.

This year also marked the end of the five year Massachusetts Breeding Bird Atlas.  I will certainly miss going out in the field trying to track down all the various breeding birds in my assigned blocks.  I will especially miss my trips down the restricted Prescott Peninsula which provided me with innumerable great experiences during the five years of the project.  Finding one of the only records of breeding Red Crossbills during the atlas was a major highlight for me.  Besides the atlas, I participated in other bird census research including a breeding bird survey route, Christmas bird counts, bird surveys and many contributions to eBird.  The cornell eBird project is a great way to let your day to day sightings have scientific value as well being a great way to keep track of your own records.  This year alone I submitted over 1900 eBird reports bringing my total to nearly 8000. 

Red Phalarope, Quabbin Park, MA

Wild Turkeys, Quabbin, MA

Common Nighthawk, Belchertown, MA

Mourning Warbler, Quabbin, MA

Snow Buntings, Quabbin Park, MA

Northern Pintails, Quabbin Park, MA
There were many other great birding moments around the local area such as a Red Phalarope at Quabbin Park (a rare occurrence inland in the state), the annual arrival of various neotropical migrants, the August migration of Common Nighthawks, the September movement of raptors as they head south, the fall arrival of waterfowl, the winter arrival of birds from the north and on and on....
Mink

Rose-breasted Grosbeak, Amherst bike path, MA
This year saw the loss of another birder in the area that I had gotten to know over the years.  Deedee Minear lost her long battle with cancer.  She was always a fixture along the rail trail in Amherst and I have many fond memories of running across her on a morning outing there in spring and comparing what we had come across so far.  There were many times we were able to bird together for a bit and enjoy the antics of the resident Mink as it worked its way around the many marshy areas.  I will always treasure the old Quabbin map she gave me several years ago as well as a copy of Donald Kroodsma’s book on bird song with a nice note in it about us meeting once along the bike path and enjoying the first of season sighting of a Rose-breasted Grosbeak.
Wilson helping me recover after surgery
This year also marked the arrival of the newest member of the family, our new dog Wilson.  He has filled a bit of the void left when we lost Kody but he is not looked at as a replacement.  He has his own unique personality and has become a big part of our lives.
