I'm off to a good start for the month of September with 22 species so far and still need to add a Blue winged Warbler (which should be easy but I have missed it so far). Any other additions for the month will be somewhat on the rare side (like Mourning Warbler and Connecticut Warbler).
I was out before dawn on the first and after looking for some nocturnal species I spent much of that morning around the south Quabbin/Belchertown area in search of warblers and had 17 species for the day including multiple Cape May Warblers.
On the second I concentrated on spots along the river from Holyoke north and despite a lot of looking I only managed to add one more species for the month (Yellow Warbler) with a paltry seven species total! Very low for the time of year and areas covered.
Today I started off in Ware and then worked my way back to Belchertown and had a decent morning with 18 species including more Cape May Warblers and my first Magnolia, Blackburnian, Blackpoll and Wilson's Warblers for the month (any day with a Wilson's Warbler is a good day).
