September has now come to an end and with it the peak of fall warbler migration.  During the month I managed to find 27 species of warbler, which is about average for the month.  Among the notable sightings were three Connecticut Warblers, loads of Tennessee Warbler and Nashville Warblers with less than expected numbers of Cape May Warblers.  Overall the month was less than typical for overall numbers and I suspect this is mainly due to a large number of days with great migration conditions which let the birds fly on by heading to the south.  Some notable days during the past week or so included the East Meadows, ArcadiaArcadiaQuabbin ParkArcadia and the East Meadows.  The species diversity and overall numbers change from day to day mainly due to the arrival of north winds which moves the birds south.

October will still feature a fair number of warblers with the vast majority as far as numbers go being Yellow rumped Warblers.  As the fall season moves along the overall numbers and diversity drop off quickly but the chances of a rare species showing up goes up so certainly worth being outside in the ever increasing cold weather in the hopes of finding something unusual.
