I’ve had this experience in NE WA. Myself and a wildlife biologist friend
(who is very adept at distinguishing flycatcher vocalizations) were both
baffled by what we heard and just “knew” must be a Mountain chickadee, only
to have a Black-capped appear on a branch and show us the truth. Now, I
trust I’m hearing a chickadee…but I try my darndest to verify with visual.
