per acre. The tract in question is gently
sloping toward the south; while there is no water
on it, water is within easy reach, at the
camp ground spring 100 yards to the east or at
the first willow bog 200 yards to the south.
The vegetation is mixed conifer and chaparral,
the later by area predominating and consisting
almost solely of ceanothus cordulatus, so greatly
like by many birds because it affords safe
nesting places plus (right now) an abundance
of insect life. The conifers on it are chiefly
firs (white), but there are also lone yellow pines,
affording lofty perches, and some incense cedars.

We have seen many other birds on our plot, besides
those named on the map - foragers or vagrants from
adjacent ground; for example, Calif. Purple Finches,
Siskins, and Evening Grosbeaks; and at night, Pacific
Nighthawks. One puzzling case is that of
Calliope Hummers, of which 4 males have separate
distinct "stands" on our plot. The females come
onto the plot to forage about the castillejas
plentiful in the brush, but as far as we can
judge, these females are only visitors, having there [sic]
nests off somewhere, probably in the belt of lodge-
pole pines down along the willow-bogs, where
the males do not go. One male has
his "stand" one telefone [sic] wire, which crosses
our plot near its southern boundary. Beneath
