actively. At one time one of them saw something on the surface of the water that he apparently wanted. It was perhaps 25 ft. away. He lifted his wings and beat them lightly above his back, and at the same time I judge he used his feet for swimming, using both methods of pro- pulsion. He fairly spun over the water, snapped up the snorel and settled quietly on the surface. Only two swallows, no Lullabys. I heard the Cynny Nuttatchers again in the redwoods near the cottage. Heard Groshawk. No vireos or warblers heard. Aug. 13 A family of Cassin Vireos spent an hour or so near the cottage. The song was heard several times, the ordinary calls repeatedly and the call of the young bird a few times. A Black-headed Grosbeak called and Cynny Nuttatchers were heard again. 2 Paleolated Warblers seen. Cooler. Very pleasant. Aug. 15. High fog lasted until noon. A large, noisy flock of Pygmy Nuttatchers went through - not just one family. A Brown Towhee was seen feeding a grown youngster. Returned to Berkeley in the afternoon. Heard a Hutton Vireo at Boulder Creek - the first time this year. Aug. 18 University work began. Aug. 20 Sat. Drove to Boulder Creek at 3 p.m. Before leaving, in the morning, I noticed the call of a W. Winter Wren near the lower pool. It stays there all the morning.
