The Lower Palo Prieta Eagle was seen leaving the Nest Tree as I drove past. This bird was circling above Ortega Spring when I drove on out of the area. At least fifty young squirrels (Beechey) were seen running about on the flat across from the old word place at the mouth of Palo Prieta Canyon. The Cholame flats couldn't look any worse. R.E.

A dead calf was observed on the hay that had been put out the previous day. Carcasses of other calves could be seen buried under the hay. On the ground about one-half mile east of the foot of Kerr Grade 21 Raven were hopping about, and perched on the carcass of a cow that had been dead about two weeks. A Swainson's Hawk was seen to fly in and land in the Swainson's Hawk top of an oak on the hillside about one-quarter mile SE of the foot of Kerr Grade at 11:30 A.M. Soon another Swainson's Hawk dropped in from above and alighting on the back of the former. Copulation occurred with the top, or presumably male bird, gently flapping its wings to maintain balance. Following copulation the upper hawk flew out and circled for a while before alighting -
