posts and two young were observed climbing up a mesh fence. I doubt that they are able to climb like a Sciurus, for instance). Only the young were observed climbing.

I left Berenice about 5:30 P.M. and drove here - a distance of about 40 miles. This necessitates going around the spur of the Lemhi Mts. and thus getting into Bird Creek Valley.
