KDixon 1950 Psaltriparus minimus May 2. Strawberry Canyon, Alameda Co., Calif. - rainy - 5:20 pm - noted family group of Bush-tits in oak-lauel grove about 100 feet N of Poetry Research Lab. - one bob-tailed juvenile and 2 parents seen and from calls, at least two other young birds were present. May 3. Family group in willow at E end of pool. 5 bob-tailed juveniles tended on branch huddled as if for warmth (three faced E one week, next E) 6th juvenile (bob-tailed) hopped about as if foraging for itself. One adult seen during 2-3 minutes I watched. 8:40 AM, cloudbursting over; cold enough that one's breath condensed. Sept. 22. 3 1/2 mi. S and 3 1/2 mi. W Benton, ±7000 ft., Mono Co., Calif. about 4:00 pm (cloudy) I ran onto a flock of about 15 Bush-tits in pinons NE & down talus slope from our camp. The birds were accompanied by four Mountain Chickadees which sometimes moved independently but seemed to rejoin the Bush-tits, at least after one separation. The Bush-tit moved rapidly, foraging in one pinion or a group of trees then flying on to other trees. The trees here were widely spaced (Junipers not present). The Bush-tits did not utilize the low Artemesia shrubs for forage during the 20 minutes or so of my following the flock. I took one bird; subsequently the birds were shy of me and would not perch in sight of me, being particularly frightened if I swung the gun barrel in their direction. Their flight from open perch to cover was a frantic dive; half a dozen birds remained on the "inside" of a tree for several minutes & I wasn't able to collect any.
