Jan. 26, 1946 - Las Trampas Canyon, Contra Costa Co., Calif.
covered west-facing slope of canyon to ridge top.
The slopes on this side of the canyon are very
much overgrazed by cattle. Birds seen out on these
open grassy slopes are: hermit thrush, junco,
black phoebe, Audubon warblers, white-crowned
sparrow, red-shafted flicker, western meadowlark,
nolin, adult red-tailed hawk, lark sparrows. These
latter two species were seen flying over the slope.
Just prior to climbing up the open east slope,
4+ fox sparrows were seen in a snowberry thicket.
A very strong and cold wind sweeps across the open
hill slopes making everyone rather uncomfortable at
times. A Odacolous hemicus was seen near the
slope of the
base of the east canyon. The search for birds on
the open grassy slopes continued until 11:30 a.m.
Western Bluebird, rufous-crowned sparrow and
vulture were also seen. We then entered a chamise
covered sw facing slope. There in the 3 to 4 ft high
chamise we saw brown towhees, California jays
and bell sparrows (2). Another vulture is seen.
The hawks and vultures are holding their wings
in a manner different than usual. The strong
wind apparently is the cause. The wings are held
at a more bowed angle and the fingers aren't spread.
Bewick wrens and brush-tits are also seen in the
chamise. Back down into the canyon bottom along
the running creek (at 12:45 p.m.) nuttall woodpecker,
