 Saturday,  I got my first look at a Gray-Cheeked/ Bicknel's. The bird =

to which bird I heard. Furthermore, My Peterson CD. Eastern/Central Bird =
Songs version of a Gray-Cheeked Thrush sounded different from the Thayer =
version. In fact I thought in some ways it sounded more like a =
Bicknel's. Anybody know any easy sure fire ways to separate the two =
auditorily. I find the songs fairly complex ....  in my Thayer versions =
the Gray-Cheeked seemed to be a Four part song with the last notes being =
fairly emphatic and ending on downward note like a declarative =
statement. The Bicknell's always seemed to end on an  slightly upward =
note like an interrogative. I also notcied that
the introductory notes for the Gray-Cheeked reminded me of the call =
notes of a Scarlet Tanager (sort of a  strecth). Still these to me are =
subtle differances and am doubtful that I will remember these finer =
points by the time I cross paths with another Gray-Cheeked /Bicknell's =
thrush. The bird was seen in the woods behind the  Snickers Gap =
Hawkwatch on Saturday around 7:30 am.  The hawk flight was another good =
day for Snickers with a grand total of 920 raptors recorded=20
