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)
