Paul DeBenedictis 1961 June 29 Donner Lake, Nevada Co., Calif. About 4 I went birding near the cabin. Only two notable, a yellow warbler and olive-sided flycatcher in an alder area. Also saw Steller Jays, robins, juncos, pewees, White Br. W-thatch, W. Tanagers, Brewer blackbirds, McDougal warbler, warbling vireo, and, later, over Donner Lake? western gulls and rough- winged swallows (some showed much blue on the body, but consistently dark wings. Belly uniform white, tail dark above, throat?). June 30. Went to the south and west sides of Donner Lake. West side is quite built up but a fire road on the south side is very wild, with many birds (flycatchers, etc., one s-lichen), and many Papilio's. We didn't stop anywhere, however. When we got back I went butterfly collecting. In the chaparral area no birds but one Sceloporus. I took 2 ?♂s Chlosyne palla, a ♀ Philotes, a ♀ Lycaena, and finding nothing else, went to by the grassy areas. (Broke my net's handle). The grassy areas were a little better. Got 2 ?♀s anna blues, a ♀ Saepiolus blue, a shipper, a ♀ Phycoides (? bauna!), and saw many other crescents, Papilio's, and one frit. Birds made better showing also, with pewees, robins, Steller jays, one gon juncos abundant, mixed with a few olive sided flycatchers, yellow & wilson warblers red-Br. W-thatches, Vermil Thrush, ? vireos, and West. Tanagers. One or two chipmunks; I heard green-
