Thanks Bill. I did hear a few typical "Lincoln's/Swamp sparrow" "dzzzzt"s but was not confident enough to report. If there were that few Black-throated Blues, I'm curious what most of the abrupt "tsip" notes might have been? There were certainly way fewer of what I would consider typical buzzy Dendroica-type "zeet" notes than what I'm used to hearing on most nights.
