What birds common to the Pacific Northwest are the best imitators?
For the past several days, we've been hearing a bird call that sounds a lot like a police whistle, blown quite forcefully, enough to make you stop dead in your tracks and look around in alarm for the police officer.
Actually the call has two tones; the first tone sounds exactly like a police whistle, while the 2nd tone, somewhat lower and less forceful, could pass for a police whistle but also sounds more birdlike.
The bird calls most actively in the morning, but I've also heard it in the evening.
After asking here and elsewhere, I've learned that no bird has such a call naturally, and that it is all but certainly an imitator.
We're in Bellevue, near Seattle. What imitators are the most likely candidates?
Thanks,
Greg
