Hi everyone, After originally hearing that soft song, I too thought that there was something not quite right about the timbre of the song in order for it to be a full out White-eyed Vireo. Hearing an Am. Robin in the background, singing an early dawn song, I thought about other birds that might have become active and which might possibly be able to mimic a W-e Vireo. One that came to mind was Blue-gray Gnatcatcher. I've often heard them whisper quiet imitations of other species, after pishing them in.
But, now that Marshall mentions Ovenbird flight song, that makes total sense. I've certainly heard Ovenbird flight song containing snippets of Red-eyed Vireo in them. I have to concur with that suggestion. Thoughts? Others? Marshall, my understanding is that these were detections grabbed real-time, with three seconds of padding added to each detection. So, unless there were multiple back-to-back detections, there probably isn't a continuous recording data set. Is this correct, Steve? Thanks! Sincerely, Chris T-H Marshall J.
