Bowman 1952 31. Journal. Aug. 31. 6 mi. S. Bernalillo, 5300 ft., Sandoval Co., N.M. -- [See preceding p.] to oak and yellow pine on the higher slopes. Apparently we are noticing a local 'inversion' of the life zones possibly due to cold air drainage into the valley where we are camped. Grey-backed Junco, Mt. Chickadee and House Wren observed in the spruce-fir association. The ground is moist and there is considerable mossy growth on soil. Yesterday (Aug 27) Ward C. Russell captured 3 plethodontids here. Captured the following in the 25 Museum Specials set out on a steep S-facing slope of T Jemez Cr.: 3ad & 3im. Peromysc sp. & One Lark Sparrow shot by WCR at camp. [T emp. at 10:00 AM, drying was 41.4°C]. One Turkey Vulture noted at 2:00 PM. While hiking upstream on Jemez Cr. for a distance of approx. 1 mi. discovered two more Beaver dams -- one made of stones alone piled about 1 ft high across stream, and a second made of small logs and stones. Also discovered another beaver house, apparently occupied (as evidenced by the freshly cut matted grass immediately at the entrance to house). Found the humerus and tail vertebrae of a 'young' (?) beaver near this house. Captured 2, 2" long (body length less legs) Rana boylii & saw several large tailed & legged tadpoles presumably of this species in Jemez Cr. Saw at least 2 House Wrens along the creek. Was greatly impressed by the active 'bouncing' action of the House Wren -- alternating left with right leg -- 'rapid pairing'?
