I had a possible Philadelphia Vireo at Lyons Ferry State Park this
morning at ~8:30. I got a good look at it singing and among other
details, it looked essentially like a Warbling Vireo but was singing
short up and down slurred phrases, much like Red-eyed Vireo, with long
(1-2 sec) breaks in between.

Unfortunately, it was not very confiding and disappeared before I was
able to get an audio recording or pictures. If anyone is out that way
tomorrow, it was just south of the main restrooms at about 46.595122,
-118.219047.
