Detalhes da observação
Massive overnight flight that carried into the morning. Very conservative estimate. I don't have the bandwidth to keep up w this number of calls, but Nighthawk software reported 2200 bobolink call notes + a few hundred icteridae sp. over the course of the night. I found that nearly all icteridae were bobolink as well as a number ID'd only as passerine sp. Given nature of NFC counting this is a very conservative estimate. I've attached several examples of groups of birds, but calls were nearly constant with many occasions where what seemed to be flocks were passing over. Confident >300 birds in this window, but would guess it easily could have been 2-3x that in actuality.
