Observation details
Singing a slightly atypical, descending song from here (48.5570514, -120.3529634). I took a recording immediately luckily, as it stopped singing after about a minute. While my immediate reaction was wtsp, I debated gcsp. However, the spectrogram looks better for wtsp, with the descending notes seperated and not slurred, and the repetitious “can-a-da” part looking good for wtsp as well. I most often hear the ascending wtsp song, but I think this sounds fine for the descending song (see the second song on Merlin for reference). Never seen well, only glimpsed, but appeared to have a white throat and supercilium in flight. ID primarily based off song. After reviewing many audio recordings of both wtsp and gcsp, I am confident that this is a wtsp. There is no slurring in the first few notes whatsoever, which in all of the gcsp recordings I reviewed seems essential. The stair stepping down pattern with enunciated drops between notes (not slurring) matches wtsp well, and the “can-a-da, can-a-da” part of the song is a great match with wtsp song of course.
