Eared or Horned Grebe - one in full breeding plumage observed for over a half hour with 7X binocs at distances from 50 to 125 yards. Light was fine, and observations were made with rests, from granite rocks above the water. Lighter colored plumes on side of head had position of that shown in pics for the eared grebe, but no black crest was observed. Further, there appeared to be a rusty color on the neck. Also, the sides were a rich, and quite bright chestnut or ferruginous filling in a considerable portion of the sideview of the bird riding on the water. The bird would swim away from passing rowboards, motor boats and canoes, but was not observed to dive to escape these boats. Killdeer - seen the morning of the 5th. just 1. Spotted Sandpiper - about 4 pairs of adults seen, and on one stretch of lake shore we found a brood of 4 downy young running around. One was caught Sat.(the 4th) p.m. and banded, but the others escaped. We returned to the same stretchof lakeshore, and cornering the family on a rocky peninsula, Ard and I caught all 4 of the young, releasing the one banded the day before. Size IA bands used were: 4I-152117, 122, 123, and 125. Young were downy gray color, with darker stripe down middle of back. One young escaped us by taking to the water, and as I reached for it, it definitely "duck-dived" and swam a few inches under water, using its wings for propulsion. It repeated this feat three times in a row, but only for short distances. Then it rode in the water like a phalarope, and swam a full 40 feet across a small bay off the lake. Pacific Nighthawk - 1 was seen coursing over the lake the p.m. of the 4th. By 9 a.m., the 5th, between 18 and 24 of them were feeding over this same arm of the lake where one had been the day before. Anna Hummingbirds - several seen. Red-shafted Flicker - 1 heard. Red-breasted or Sierra Yellow-bellied Sapsucker - 2 or 3 seen. Hairy Woodpecker - 1 seen working pines near camp. White-headed Woodpecker - several seen and others heard. Black Phoebe - at least 2 seen at the lake. Western Flycatcher - several seen - one pair were feeding young not long from nest. Wood Pewee - a few Traill Flycatchers very common Olive-sided Flycatcher - several seen, and others heard calling - usually on hi perch.
