The Rocky Mountain Titmouse was discovered by the late Dr. Gambbl, near Santa F6. It is nearly allied to the P. Atrieapillus,
but may be distinguished from it by the lines of white running over the eye, and white front. Dr. Gambbl gives the following
account of this bird: “This new and distinct species I first observed about a day's journey, from Santa Fe, in New Mexico, and
from thence in all the ranges of the Rocky Mountains, nearly to California. Its manners and notes are very much like those of
the common Chicadee, but the latter are more weak and varied. It keeps, also, much in low bushes, where, from morning to night,
with untiring patience and activity, it may be seen hopping from bush to bush, searching them minutely for small insects. It also
frequently descends to the ground, to pick up small seeds; when thus occupied, it occasionally stops, looks around, and utters a slender
te-de-de-de then, altering to de-de-dait, flies off to some other bush. On the Rio Colorado, it kept much in the cotton-wood trees
which grew along its banks, and its notes, which became familiar, were almost the only ones heard in the winter, when we were
there, to cheer our course. This species is sometimes seen in company with the P . Minimus and Regulus Calendula, which at this
time are roving in large and busy flocks along the small streams.
“ Although so very abundant in the western ranges of the Rocky Mountains, particularly near the Great Salt Lake, where, in
some of the high wooded mountains, the trees were almost alive with them, yet I never saw them on the other side of the
Californian ridge—much to my surprise—where the other species of Titmice so abound.”
Dr. Coues found this Tit. resident throughout the Territory of Arizona, particularly in the pine tracts, but nowhere very numerous.
