For the past month, or more, a bird has been calling, practically 
non-stop, all night long. The call is a single clear slightly 
descending whistle. Sometimes, I think I hear  a low chuff just before 
the whistle. This is in a little canyon in the Oakland Hills, just 
south of Knowland Park. Could it possibly be a Poor-will? I have never 
seen them mentioned in our Listserve. I've been here 5 years and this 
is the first time I have heard it.

Any ideas?
