1944 Journal Bill Harvey April 5 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.
