April 24, 1946 12-mile Swamp, McFadden's 2-5 p.m. With Charley Cutress Great Blue Heron - saw just one at quite a distance. Mallard - Saw several pairs and found the nests of two pair. One had 10 and the other 11 eggs in the set. Green-winged Teal - present in considerable numbers. Shoveller - Saw several males, but could not identify any females. Turkey-Vulture - Several seen soaring over the marsh this p.m. Red-tailed Hawk - saw just one over the swamp area. Bob-White Quail - saw just one in field adjacent to the swamp. Pheasants - seemed plentiful in all areas around the swamp. Virginia Rail - Saw three birds, and found two nests. 10 eggs in one, 11 in the other. Killdeer - a pair seemed to have a nest in the gravel along the road by the swamp. Greater Yellow-legs - Saw a few solitary ones and one flock or 30 or so of them wading in the swamp. They wheeled and banked in flight just like Teal. They were very noisy and gave their "kip kip kip" frequently. Wilson Snipe - I flushed them by the dozens this p.m. They were everywhere I walked. Mourning Dove - saw just one. Barn Owl - I found a light, but richly colored individual in some scrub ash in a thicket out in the swamp area. It flew and Redwings chased it all the way cross the swamp. Violet-green Swallows - many were over the swamp area this p.m. Western Crow - saw a few individuals flying over. Western Marsh Wren - We found one nest with 5 fresh eggs in it. Cassin's Vireo - some singing in the ash thickets around the swamp. Pacific Yellow-throat - saw two of them in the same ash thickets. Sang occasionally. Eng. Sparrow - some around a barn in the vicinity. NW Redwing - Along the west side of the main swamp I found several freshly made nests, some still rather moist inside, but none with eggs in them. On the east side of the swamp I found fresh nests, but also over half a dozen of them with full sets of 4 eggs in them. The bluish tinge was washed out in some of them. All in new nest Willow Goldfinch - saw a few around today. Western Tree Sparrow - I saw four of them, two males and two females. I do not know what other species they could possibly be. They were buffy and brown-black streaked on the back, and the underparts were gray-white. The crown was bright rufous, and there was a similar patch on the side of the chest. There was a distinctly plain small blackish dot in the center of the chest. I do not recall the females as having the spot on the chest. They were in a brier and ash fence row, or stunted growth. The brightest male I saw was perched on a fence post just 15 feet away. W. Chipping Sparrow - Saw a few in the ash trees around the swamp. Golden-crowned Sparrow - Saw just a pair of them in a fence row near the swamp. Song Sparrow - I just missed capturing a 1/2 - 2/3 grown one in a clump of brush at the swamp. Its tail was exceedingly short, and it could fly only a short dista dtance at a time. April 25, 1946 - Dixon Creek Ridge, north of Corvallis. 1 - 4 p.m. Brks ovc. at 2000'. Turkey Vultures feeding on dead Black-tailed Jack-rabbit. It was completely gutted, and most of the meat was still on the legs, etc. Sparrow Hawk - One was seen carrying a Thamnophis about 2 feet long. Oregon Ruffed Grouse - ll of us were clustered together in one spot on the north side of the hill taking readings of temp., etc., and one of the boys spotted a grouse on a nest, and it was almost surrounded by us. One of the boys was sitting against the base of the very small fir on opposite side to the nest, which was at the base of it. He was less than 1/2 feet from it ! The bird never batted an eye, but trusted in its camoflage. Later Dr. Gordon and I took pictures and it stayed on all the time he set up the tripod, put in the cartridge, and took the shots, less than 4 feet away ! But I flushed it when I tried to get the camera less than 3 feet from it. Whoom !!!! There were 10 eggs in the nest. The cavity was a little over an inch deep, and 6 - 7 inches in diameter, and lined with last fall's Big-leaf Maple leaves. Grasses and twigs made up the bulk of the nest. The nest was at the base of the small fir, on the north side, and was openly exposed from all other sides. A few short sprigs of Poison Oak were growing around the nest. Ensky Horned Owl - Charley Cutress showed me the nest he located the week before. The adult was not around, but the young had gray-white down, with a few pin-feathers sticking through here and there.
