Putelka 1943 Myiarchus cinerascens June 12 2 mi SE Beegum, 1650 ft., Tehama Co., Calif. Common in the blue-oak and digger pine. Pairs are regularly spaced throughout the pine-oak woodland at distances of about 250-300 feet. They call and move about frequently, and Territorial encounters are apparently numerous. Nesting sites for this species are abundant, as most of the larger oaks, dead or partly living, have cavities. This species was found on the slopes north of Camp as well as on the valley flat, though, of course, over the former area, it was less frequent because of limited suitable habitat. June 13-15 Distributed generally in the woodland of the south slope, but most abundant on the valley flat. 2 mi E Hayfork, 2400 ft., Trinity Co., Calif. June 16-20. Regularly present and fairly common in the dryer, open stands of yellow pine, Garry oak, and black oak, as, for example, along Duncan Gulch and on the upland west of Big Creek (opposite Big Creek Ranch). The species is not present, however, as abundantly as it was at Beegum. June 24-26 1 mi W Hyampom, 1200 ft., Trinity Co., Calif. Fairly common. Present chiefly about poplar and willow groves on the Hyampom flex. Also present in open woodland, chiefly Garry oak, near the top of a south-facing slope above Camp.
