Cogswell 1950 Zonotrichia leucophrys (orianta) June 17 near Sugar Bowl Lodge, 7000 ft., 1.2 mi. SSW Donner Pass, Placer Co., Calif. - 8-12 jrs. in the willow thickets of "Cowgill meadow" on N facing slope at base of Disney Peak. 1 pair was seen copulating, or at least attempting it, 4 times in quick succession. The ? each time postured with tail held up at 70° angle, wings down & quivering, a head up, bill slightly open. The male ran along the ground from distances as far as 8 ft. & mounted immediately when she so postured. The whole process lasted about 30-40 sec. Another pair noted while the ? was carrying a .2 with long tuft of some 30-35 whitish mammal hairs (dog?). She hopped thru the bushes for some time with it, & the ? interrupted his singing to come join her in scolding me. She eventually dropped the hair on the ground amid the willow stems. Late June - Singing was noticeably stronger & more persistent after the snow was melting rapidly from willow thickets & buds were breaking into tiny leaves or about June 20-25. June 22 E side Boca Res., 5100 ft., Nevada Co., Calif. - Several singing from sagebrush (!!) on dry flat just above small, wet grassy swales. No willows or other large, soft leaved shrubs anywhere near. June 24 W end Donner L. 6000 ft., Nevada Co., Calif. - 1 heard singing in willow thickets amid aspens & pines, & some open grass along Shelt Creek.
