I spent the last four mornings at Arcadia taking advantage of good overnight migration conditions, beautiful mid September weather with cool nights and sunny days (except for today) and some time off.  My main focus was on tracking down warblers before many of the species disappear to the south for winter (birds are smarter than us in that respect!).  Much more on warblers for the four days can be found at the following link.  I did something similar last year too and it was interesting to see the difference from one year to another as well as one day to another.

On Wednesday I arrived to a cool and calm Arcadia with just a small amount of fog.  The activity slowly picked up after I arrived and I found a couple Cape May Warblers travelling together.  As I was trying to get some photos of them another bird popped up and it was a Connecticut Warbler!  The bird actually stayed in view for over a minute (an eternity for the species) and despite the low light levels I got some photos.  I then walked a few more miles and ran across a number of pockets of birds with a few mixed species flocks including some high counts of a number of warblers with double digit counts of Tennessee Warbler, Nashville Warbler, Northern Parula plus others and also had a couple of slightly late Yellow Warblers and my first 'yellow' Palm Warbler of the fall.  Non warbler highlights included Great crested Flycatcher, a couple Tree Swallows, three Swainson's Thrushes, almost a dozen Lincoln's Sparrows and five Scarlet Tanagers and others...check out the list linked above.  I had 84 species during my four and a half hours there and almost 90 by the end of the day after taking some walks with Wilson.

Thursday was an even cooler morning with temps starting off in the low 40's.  Activity was a bit slower compared to the previous day but it was still a very productive morning with a total of 70 species at Arcadia and a total of 91 for the entire day in the county.  I covered most of the same areas as the previous day but missed a couple spots and spent less time at Arcadia overall.  Highlights included the four Sandhill Cranes that have been in the area for several weeks, a continued Great Crested Flycatcher and a total of a dozen species of warblers including above typical numbers of Nashville Warbler and Tennessee Warblers as well as a late juvenile Yellow Warbler.  My next stop across the river at Silvio Conte NWR-Fort River produced some slightly late Tree Swallows and a Bank Swallow, at least one Marsh Wren, a Connecticut Warbler and a flyover Dickcissel.  A final stop at a spot in Belchertown produced several Cape May Warblers and a Bay breasted Warbler with an extensive amount of rufous coloration remaining (even in areas there should not have been rufous even in a breeding plumage bird).

My third morning at Arcadia featured another great showing of species with a big raptor highlight at the end of my time there...more on that spectacle at an earlier post: Big Broad winged Hawk flight.  One of the big highlights for me was finding not one, but two very early Orange crowned Warblers among a total of 15 species of warblers there....I missed it being my earliest date for Orange crowned Warbler in the county by a day and usually I don't find the warbler here until October.  Great numbers of Tennessee Warblers, Nashville Warblers, Cape May Warblers, Northern Parula and Chestnut sided Warblers continued (or increased) from previous mornings.  Other unusual/late species around included Least Flycatcher and Warbling Vireo plus above typical counts for a number of other species with a total species count for the morning there totaling 81 species (check out the eBird list linked above for totals and lots more photos).  A couple other stops later in the day when out with Wilson kicked the total for the day up to 88 species.

To end my mornings at Arcadia I met up with former valley birder Devin for a fruitless quest to finally find him a Connecticut Warbler in the county.  The cloudy, cool and breezy conditions did not help us at all.  Nonetheless we still had a decent morning and did bag him a new county bird with a view of the continued Sandhill Cranes.  As expected with the above mentioned weather conditions the activity was much reduced from previous mornings but we still had 69 species total with several counts that tripped the eBird filters but no real rarities beyond the cranes.  We had a lucky 13 species of warbler including my first Black throated Blue Warbler in the last few mornings.  The weather also made photography a bit difficult so not nearly as many photos as previous mornings.  I didn't have time to hit any other spots on my way home beyond very brief visits due to rain and other pending commitments.  

During my four mornings at Arcadia I found a total of 103 species (trip report link here) and when including my other stops during this time period I had 114 species (that trip report link here).  My best morning I got to 91 species and I'm sure with a little more effort and birding through the afternoon I could have broken the 100 species mark without too much difficulty showing that there is still some decent diversity around here through mid September.
