rocking, sagelush valley a buteo which was very light
in primaries, body s and tail, but with some dark markings
here also. This we called a rough-legged hawke. It was soon
lost to view. At Palm Oasis in in Valleides the temperature
was very warm, but there is a permanent water supply here
and many birds. Phainopepla's are most abundant here, flying
out to catch insects and back again. The sexes are colored
similarly, but the ♀ is duller black, while the ♂ is glossy
black, both show crests. The only song heard was sort of
dungbird like clucking and whistling. The white in its
wings is a very obvious marking in these, reminiscent of
its mocking-bird pattern and perhaps performs the same function
(startles insects?). We went fossil hunting with the LACM
museum party up Tapiado wash, not much found but
> 90°F in shade temperatures. Even the dry desert washes
had vegetation. Ted Downs says it's a good, wet year.
