Record setting August and an update on life totals thanks to the latest taxonomic update with eBird

August is now about over and with it a record setting month once again for me in Hampshire County with a total of 152 species (beating my previous best August total of 151, which I reached last year).  The record setting total is a combination of some lingering unusual species as well as some early fall migration arrivals and some storm dropped birds (unfortunately I missed out on a few other species that dropped in at the end of Henri as I was stuck at work).  The first eight months of the year has produced 230 species in the county which is the highest total I have ever had at this point on the year (previous highest by the end of August totaled 222 in 2019 and 2020).

Sedge Wren, Arcadia, Northampton, MA, Sep 17, 2016

The latest update to the taxonomic list with eBird is now complete and I gained a couple species with the split of two species.  The first was the overdue split of Rufous capped Warbler into two species with the more southerly yellow bellied birds now being labeled as Chestnut capped Warbler and the northern birds (from Mexico/Guatemala border north) retaining the name Rufous capped Warbler. The second split that impacted my list involved Sedge Wren.  The northern migratory species was split from the more southern sedentary species that occurs from central Mexico into South America with the migratory species keeping the name Sedge Wren and the southern birds now known as Grass Wren.  With these changes I now have 1582 species on my life list according to eBird.  More on all the changes within the AOS in 2021 can be found at the following link.
