Feb.12th. No observations today other than to note presence of B (with song) and Rhody, and to feed them both before leaving for Leconte Thrasher territory in the vicinity of Coalinga as described by Dr. Grinnell in May-June Condor,1933.; with Dr. Reynolds I hoped to see these birds and compare their song with the California thrashers. Feb. 13th. We were at Polvadero Gap about 5:30 A.M. and worked about through the widely scattered atriplex on the Guijarral Hills, seeing and hearing no thrashers. Dense clouds and rain threat- ening; a small, clear opening in the clouds at the expected point of sunrise; nothing but meadow-larks and cocks were heard. As the sun was rising a little after 7 in a gorgeous display of color, we went down into the gap where the atriplex was thicker and higher and a dry barranca, with a few cottonwoods growing in it, meander- ed. This proved to be the thrasher habitat, though we did not positively prove it until we had about decided that, owing to the dull and chilly morning, they were in cover and probably would not sing. We had heard previously a few calls which we suspected to to have been made by these birds, since they were new to us, but no song. Finally a distant song was heard which seemed to be of "thrasher type" though differing radically from the full song of Brownie and his tribe, and perhaps an hour and a half later, we were rewarded by hearing the full song coming from a thrasher sitting on a bush about 100 feet away. The bird shortly disap- peared in the bushes, but by the time the doctor had returned with the 6x glasses (which we had forgotten) he was again in full sight and song nearer than before, as we had moved up on him. We watched and listened for several minutes. He did not strike us
