Tweeters-
I have been hiking alot the past few weeks at the 3500 - 5000 ft. elevations
on the east side of the Cascades. I have been trying to figure out why I
sometimes see Mountain Chicadees and sometimes Chestnut-backed Chicadees.
While the Mtn. tend to occur at higher elevations and in drier habitats,
I am often surprised by Chestnut-backeds where I don't expect them. Are
there other habitat characteristics that predispose to one species or the
other? I would appreciate any thoughts. Thanks.
