I originally posted this photo as a Peregrine Falcon, but have since been corrected by several Inland Birders and friends.
I ran this by Jerry Ligouri and others and am now satisfied that it is indeed an adult Gray phase Gyrfalcon.

Ironically, the original intent of our trip this morning was to see if any Snowy Owls or Gyrfalcons had shown up yet on Peola Road, Asotin county.

This location is only a a couple of miles from a this February 2009 adult female gray phase bird http://www.flickr.com/photos/birddog/3314884830/
