Remsen, J.V. 1974 Fox Sparrow Passerella iliaca Jan.4 373 Gravat Dr., Oakland, Alameda Co., Calif.: G feeding on ground under feeder although no food has been put out since Dec. 14. Perhaps they are better at scratching for old seeds than other Fringillids; and thus still persist. Apr.26 Boca Dam, Nevada Co., Calif: 5 birds in a manzanita meadow were all using a perfect Olive-sided Flycatcher "quick-three-beers" to introduce songs. We had all been convinced we had heard Olive-siders the imitation was so good. June 13 Mt. Pinos, Kern Co., Calif.: Songs incorporating following were heard: White-headed Woodpecker rattle, Western Flycatcher "sweep", Dusky Flycatcher "see-lup, bzzz", Black-throated Gray Warbler song, Western Bluebird call, Com. Flicker "few" call of Apr.26 Boca Dam (cont): I've decided to elaborate a little more on this, since I impressed myself with my hearing abilities. At dawn, Kim Garrett had called out 'Olive-sided Flycatcher'. Kim is considered by many to have the best ears of any birder in the west (maybe North America). The bird was extremely far away, and Laurie Binford, who does have very good ears despite his protests to the contrary, could not hear the bird. Rich Stallcup, who has one of the best ears in Calif. also agreed with him even though it was barely audible. However, I could hear that after each quick-three-beer followed immediately a Fox Sparrow-Green-tailed Towhee song which may have been inaudible to the others. I suggested the possibility that it was part of one of their songs, but I was ignored, and I don't blame them - it was a perfect OS Flyc song. Later, however, my suspicion was verified.
