Initial impression was that of a Cerulean Warbler, but I am aware this would be a true rarity here. The shape of the song fits that of Cerulean, with complex downward notes ending in a higher buzz. The sonogram looks quite similar to a Cerulean sonogram, with the exception that the earlier portion ought to be a little lower pitched. Not many other eastern warblers end their songs with a buzz. But several of those were present at the time -- Black-throated Blue, Black-throated Green, and Northern Parula. (Prairie, Palm and Golden-winged all are totally different anyway.) Although Northern Parula were numerous, I think that ID the least likely. The only song of theirs that ends in a buzz is a western song, and the first part of the song is a very poor match for this. The song lacks the rhythm of a Black-throated Green. But Black-throated Blue has a song that begins with short notes and ends in a buzz, so that is closer. But this recording contains at least two sections of notes leading up to the buzz, and they lack the staccato sound of Black-throated Blue. One problem with attempts at an ID -- the more piercing note at the beginning. I am assuming that that is another bird, but perhaps it is part of this song? Another problem, only one rendition being available. The only other recording is obscured by a much louder Pine Warbler and is useless. Finally, maybe that last part should not be considered a buzz? If not, Blackburnian is also a possibility.
