Cogswell 1950 Aphelocoma coerulescens 2 Aug. 6 - Kingsbery Grade (New. lat. 17), 5800 ft., 2.8 mi. S, 1/2 mi. W Genoa, Douglas Co., Nev. - 2 immatures flew by easy stages up the steep S to SE-facing slope, which is sparsely dotted with 1 to 60 ft. high Jeffrey pines & has a "sagebrush" formation of Artemisia tridentata, Bursia tridentata, & somewhat higher Arctostaphylos patula. The first one seen was silent & spent a good deal of time in the manzanitas until I flushed it out, when it flew on to small pines. The other came up to investigate & called the harsh "fainck" note several times. Both had the central rectrices (1 or 2 pairs) quite gray, top of head gray brown extending over nape onto somewhat browner back. The super- ciliary was evident, the narrow & not pure white; the necklace seemed to be represented chiefly by a slight brownish suffusion at the sides. The blue of wings & part of tail was pale. - 4750 ft., 1 mi. S & slightly E Genoa, Douglas Co., Nev. 2 seen in 50 ft. high Fremont cottonwoods along irrigation ditch by road which skirts W side of marshy Carson Valley, with low sagebrush upslope to west. Both were immatures I had 2 central rectrices long, all the others short & seemingly bluer. The blue of wings & lack of a distinct necklace were noticeable. Both of them flew back & forth between trees 100 ft. apart-
