Cooper, 1936 San Andreas, Calaveras Co., Calif. April 27. off and the mate not seen. However, in the light of the large number of single birds of this nature observed, this seems unlikely. Digger ground squirrels were obser- ved, but not in abundance. Not over 15 were seen in the entire area. Three jackrabbits and 1 brush rabbit (or cottontail were noted. A lark sparrow's nest (with five eggs) was collected from an open grass- covered meadow. The nest was on the ground in the dense growth of wild oats that abounds there in the digger pine - black oak belt. The jays nest collected was secured by Mr. Wiley and donated to us. Three eggs were in it. Another nest was found, but only the three eggs from it were saved. Wiley also reported the finding of a red-tailed hawk's nest with from 4 to six downy nestlings in it. It was left unmolested. Left San Andreas at 3 P.M. and arrived in Berkeley at 6:30 P.M. The further attention. 627 birds were put in cold storage pending.
