Cogswell 1949 Chamaea fasciata 3 Aug. 26 3 mi. N Willow Creek, 700 ft., Humboldt Co., Calif. A few sang occasionally from the Tan Oak - mature Douglas Fir - Black oak forest on slopes of [illegible] Canyon. Aug. 28 Horse Lints Creek, (cont.) - The birds collected here (#'s 77, 78) both had, like those collected by Hullion at Branch Camp, a large brood patch yet the shell roof was thin + transparent. I begin to wonder whether this species develop the double roof, at least as early as its first breeding season. The other alternative is that the brood patch is either not such, or that it develops by this time of the first year. Sep. 3,4 Brannan Mtn., 3700 ft., Humboldt Co., Calif. The typical song of the male was heard both in late p.m. & early a.m. down the N. facing slope, which is primarily open pine forest with scattering of shrubs, but has some admixture of Douglas Fir, Tan oak. There are also thickets of deciduous shrubs in the bottom of the larger draws, from which I pre- sume the bird was singing. Sep. 7 (2 1/2 mi N.N.W.) Red Mtn., 5300 ft., 14 mi. S Hayfork, Trinity Co., Calif.: The song typical of the & was heard several times in the early a.m. from our camp - apparently coming from the shrubland area near the small bald just above the forest we were in. No birds of this species were located there on several subsequent coverages.
