Sept., 1909 NOTES ON SOME BIRDS OF KERN COUNTY 171 trying to beat the other to earth. They separated upon reaching a short distance from where I was standing and disappeared over a hill. In a few minutes a familiar screeching whistle echoed up the canyon and, sneaking down to a turn some hundred yards below, I saw one of them percht on a cliff a hundred feet from me. I pictured a fine mounted specimen for my den. But then it is probably better that the gun had been left behind. Falco.peregrinus anatum. Duck Hawk. One seen about the cliffs above Poso Creek, and a female taken August 16 in the Long Tom gulch. Falco sparverius. Sparrow Hawk. Common everywhere. Aluco pratincola. Barn Owl.
