What kind of bird is this

[WapitiTalk1]

Amazing, didn't know they existed in WA.

Ptarmigan for sure!  There are actually more of them in Washington than what people think.  I had one two years ago in December right off my deck that was in his full white phase.  Of course by the time I got the camera, he was gone!

With no open season hunters need to be careful.  Years ago I saw a few in the Pasayten that were almost completely void of white.  Could have made a mistake very easily.
