Bourman 1952. Journal. Aug 20. 3mi. N.S.W. Tres Piedras, 9000 ft., Rio Arriba Co., New Mexico See photos nos. 1/1, 1/2, 1/3, 1/4. Set out 25 Museum traps in an adjo[n] grove by camp. Aug 21. Temperature in shade at 6:40 A.M. at camp, 55° F. From 7:00 - 9:30 a.m. (M.S.T.) observed the following: Pygmy Nuthatch (these are the most ubiquitous birds in area, found primarily in the yellow pines They occur usually in flocks of 3 to 10. They utter several notes & calls. I have noticed a plaintive, quiet trill given when in flocks & preparing to leave for another tree feeding station. At other times a solitary bird will give an oft repeated two- parted reedy whistle. I am taken with the striking resemblance between this species of nuthatch's woodpeckers, in flight, pecking habits, etc., and relative tameness. Whereas at our Chama camp, juncos were the most conspicuous and not probably abundant small bird life, here at our Tres Piedras camp, the pygmy nuthatch forms the dominant bird species. Another note given by the pygmy nuthatch is almost finch-like in quality, given usually, but not exclusively, while feeding in small groups (2-3). This is frequently the only clue to the presence of this "mite" of a bird) Solitary Vireo (taken in open grove); 1 Calliope Hummer Steller Jay (2), White-breasted Nuthatch (2), Western Bluebird, Siskin, Williamson Sapsucker (1), Orange grey crown Grosbeak Warbler (taken), Black-headed Juncos,- - (young adults) -, Clark's Nutcracker (3), Violet-green
