Hi Tweeters,
I am unable to identify a warbler I heard and recorded this past Sunday
morning. I posted online on the Facebook group "What's This Bird?" but no
one responded, which I'm finding typical for audio ID requests. On
xeno-canto.org's forum someone suggested Audobon's Yellow-rumped Warbler or
perhaps Nashville Warbler. I also asked on a local e-mail listserv.
Nashville and Yellow-rumped again were the most common responses. Someone
suggested the sonogram looked consistent for Nashville. Personally, I don't
hear Yellow-rumped, but I realize there is some variation. I suppose it
sounds somewhat good for Nashville, I have not found a clip of Nashville on
xeno-canto or in the Macaulay Library that matches the song all too well. The
clip is here <https://www.xeno-canto.org/470856> on xeno-canto. There are
some background songs but overall I think the clip is clear enough to hear
well, so I'd love to pin it down to something concrete. The clearest
example - and best sonogram - of the song is in the 0:02-0:04 second mark,
but you can hear it again from 0:09-0:11 and 0:16-0:19. The bird was not
seen, but the sound was coming from the upper canopy of mixed deciduous
trees at the edge of dense lowland forest in rural Whatcom County around 80
minutes after sunrise.
Thanks for listening and for any suggestions,
Stephen Chase, in Everson.
