I have on one occassion seen Red Crossbills in sagebrush country. This
was near the beginning (east end) of the Wenas Road on April 15, 1989. Of
course this was not nearly so far from typical habitat but there was not a
conifer in sight. As I understand it crossbills can breed at any time of
year so I am not sure how you would identify a post fledgling dispersal.
Time of year does not seem sufficient by itself. Whatever the reason for
there presence in the sagebrush, I was fairly surprised.
