Early this morning an unusually large number of warblers (for this time of
year) seemed to be working the woods-blackburnians, redstarts,
yellow-rumped and black and whites plus other species I couldn't identify.
I've noticed this behavior before late in the day in mid-August especially
on clear days. It seems to me that warblers are aggressively feeding in
preparation for night migration on those clear nights.

It's worth going out on those clear, crisp nights around mid to late August
and you can hear the infrequent calls of birds on their way south. The
calls, as I understand it helps keeps individuals in groupings. I assume
those simple one note calls are warblers.  On the moon lite nights its
interesting to observe via a spotting scope, the birds against the light of
the moon.

With two industrial scale wind projects in the NEK, I wonder what impact
they may have on night migrators-birds and bats and also in the day those
raptors using the ridgelines.  A graduate student is keeping track of bat
mortality on Sheffield Mountain; I assume bird deaths will also be
monitored.

With all of the other perils out there, I hope the turbines won't be an
added threat.
