Cogwell 1948 Zonotrichia leucophrys sup. oct. 8 - Oxford St. Experiment Tract, Berkeley, Calif. A song heard repeatedly from at least 2 different birds which I do not recognize as of proper pattern for either Z.l. gambeli or Z.l. muttallii. I transcribe it thus: say saw (drawling) 1st 2 notes. o o child chip It is possible, I suppose, that this different song pattern may distinguish birds from another breeding locality — perhaps within the realm of Z.l. pugetensis? oct. 12 - University of California, Berkeley, Calif Same sort of song as above heard from bird in shrubbery S. of Life Sciences Bldg. 1949 apr. 3 - Asilomar, shore of Monterey Peninsula, Monterey, Ca All birds on dune shrubs were active in mid-day; males in full song. One circuitous chase occurred over an area about 80 ft. in diameter [the ♂ chasing a bird which had not been singing (=♀); but not at all vigorously].
