Just a question,
How were you able to tell between the different species of warblers. I know a few things like Bobolink and Swainson's Thrush are pretty distinct but Black-throated Blue Warbler??? BTB Warb has a short sounding seep call which is very similar to many other warbs(Redstart, BTN, Ovenbird to name only a few) Also the Worm-eaters. They are in the zeep group and are also very very similar to Magnolias, Yellow Warblers, Blackpolls ect. Pretty interesting with the Kingibrds too. They ususally aren't known for calling much at night.
Good night listening,
Matt
: Last night after returning from a friends house at 11:00 pm, I sat outside for almost an hour. There was an incredible amount of birds moving over, taking advantage of a clear night to migrate, despite the east winds. There was good diversity, but it was tough to hear much over the plentiful Black-throated Blue Warblers and Bobolinks!

: Keep in mind that there are always many other birds up in the air that are not calling. I was hoping for a Black-billed Cuckoo or a Bicknell's Thrush, but not this time ;)
