Salt 1950 Journal Boca Spring, 6000 ft., Nevada Co., Calif May 27 stricken from the list of approved cassin quick watering places. One pair came in about 6 p.m. but I missed both. The ♂ never got near the traps and the ♀ got in the trap locus + I sprung it on her but missed. During the walk went down the road to the place where we got stuck coming in. It is a grassy meadow with willows dotted through it. Belding ground squirrels were very common. Saw six or eight although could have been seeing same squirrels over after they came out of different holes. Heard a few cassin's but got no shots at them. Bailey + Dixon got some Peromyscus maniculatus and one very small light grey shrew in their traps. Sparrow hawk has been hovering over meadow. Bailey finally shot him. Heard poor-wills again after supper. Shot at bats. (few - none last night) but they didn't appear 'til dark + shooting was poor. Missed the little bats one and all. May 28. Up at 5:00. Very nice dawn chorus of rolins, green-tailed towhees, + junicos. ♂ cassin came in + sang from tree near spring. Came down to drink.
