I birded at the Greenwich Audubon Sanctuary this morning, seeing 12 warblers, including many in morning flight, Blue-headed Vireo, Scarlet Tanager, Bobolink, and Lincoln's Sparrow. The hawk flight was also quite good, and the total was around 800 when I left. 12 eagles, 2 merlins, a few harriers and coops, and lots of kestrels and sharpies joined the 600 or so Broadwings.
