1940 Clear Lake Chipping Sparrow, and Chat, and Harris Woodpecker. At Middletown we found W. Gnatcatchers which became increasingly abundant from there. W. Kingbirds first appeared beyond Middletown, as did Clark Sparrows in abundance. At Clear Lake the water was very high. Western Grebes were very abundant and we watched the nuptial dance of a pair. When first seen they were a hundred feet or more apart and began calling to each other and to swim toward each other. When they were close together they began to bow, stretch their necks, lower their heads now on one side now on the other; then suddenly they rose in the water, fluttering their wings and raising the body completely out of the water except for the feet and tips of the body. The bodies were tense and the neck stretched stiffly at an angle, thus: [sketch of two grebes] Then they lowered their bodies and sank below the water—not by diving but by settling gradually. When they came up they swam away from each other. Did they mate under water? May 10 The list of birds seen was the same as last year but Robins were seen in many places; 15-20 White Pelicans were seen. A few Forster’s Terns, Yellowthroats abundant below Antioch—Ash-throated Flycatcher very scarce. Now heard, we see. Chats were in every suitable place.
