FIELD NOTES Doug Bell LOCATION: Golden Gate Hill, 4 mi SE Mokelumne Hill, Calaveras Co., Calif. DATE: 25 April, 1987 cont. Zillions of hummingbirds about the rocks - feeding on the monkey flower blooms. About 50-100 White-throated Swifts are noisiferously zipping about two cliffs - as are many Violet-green Swallows and one pair of Cliff Swallows - apparently with a nest in a fault crack. Both Rock and Canyon Wrens heard singing. 4 Turkey Vultures out and about. One Red-tail, and one imm. coppers hawk soared past. These cliffs are very nice, and nicely isolated from most disturbance. There must be potential here for falcons. On our way back down the hill we sighted an Osprey circling out near Mokelumne Hill, almost to Jackson; then a chocolate- colored Red-tail adult and a lighter bird. An imm. Red-tail flew by. Also saw unidentified Empidonax, heard Olive-sided Flycatcher, and down near the open grassy areas w/oaks Bullark's Oriole and Calif. Quail.
