October 21, 1947, Corvallis to 12-mile Swamp, 1310-1330, 20ø cool and calm. Redtail Hawk - 1 Brewer Blackbirds - 36 Sparrow Hawk - 1 Killdeer - 108 (75 in ongroup). And return 1545-1605 20ø cool and calm. Redtail Hawk - 1 Pheasants - 18 Killdeer - 209 (100,30,22, etc) Flicker - 1 Meadowlarks - 3 Sparrow Hawk - 1 on post with Brewer's perched less than 10 feet away. English Sparrows - 4 Redwings - 25 in poplar tree Brewer Blackbirds - 125. (noticeably paired, as before). October 21, 1947, 12-mile Swamp - 1350-1445, 20ø cool and clear Pied-billed Grebe - one in shallow, high water area. Lesser Canada Geese - 11 came in from the north while we were at the shack. Flew on south. Shovellers - flushed 2 females or immatures. Wood Ducks - 3 seen on overflow area near Muddy creek. Ruddy Duck - one nearly full-plumaged male seen at north end. and? Merganser - we saw one for an instant, but did not get to identify it. It was too large to be a Hooded Merganser, I know. Osprey - I spotted one circling in a "thermal" at the north end of the swamp, and while we watched it climbed at least another 500' before deciding to level off, with slightly curved-back set wings, and head south, dropping slightly as it went, thus increasing its speed a great deal. It was soon lost too view, because of the distance and the altitude. Perhaps it found another thermal farther south, and climbed on it, leveling off, and heading south on a long glide again. This method is described in Dickey and vanhossem's Birds of El Salvador for the Swainson's Hawk. (p.17) Coot - these were about the only waterfowl seen in numbers - at least 250-300 present. Killdeer - a few heard calling. Flicker - a few on ground and in ash trees. W. Crows - a few calling Oregon Chickadees - in the scrub ash areas Seattle Wren - scolding from fence row Tule Wren - several seen, and a few heard today Western Bluebirds - flying over, calling, and in fence row areas. NW Shrike - we watched one fly from a taller ash near the swamp to a fence row several 100 yards away, and saw it make frequent sallies toward the ground after insects. It did not come towards us when we "squeeked" it, altho we did get responses out of nearby Seattle Wrens and Song Sparrows. Later it flew back where we had first seen it, and I heard it give its rather high-pitched cry or scolding (??) notes. As we left the swamp area, we saw one near the railroad trucks, possibly this same individual - who knows?? Audubon Warbler - a few in the area. NW Redwings - 40 or 50 birds in the area. Oregon Juncos in the fence rows Golden-crowned Sparrows - a few in the fence rows Song Sparrows here and there. Oregon Towhee - a few in fence rows Notes: since last week, rains raised the water level at least 15", resulting in its flooding of most of the grass + mud cows, leaving open water over most of the area. Very, very few waterfowl were present. An increase in Coots was noted; probably they were there all the time, but hidden by the vegetation previously. October 21, 1947, Oak-fir ridge 3 miles W of 12-mile Swamp, 1455-1535, Mountain Quail - flushed 6 or so near the point they have been seen other times. Flickers - in large numbers along the fence rows on the road going up the hill. Robins - a few heard in a flock Varied Thrush heard W. Bluebirds - in old orchard area, and along fence rows Golden-crowned Kinglets - heard Ruby-crowned Kinglet - one heard in same clump of bushes as last week. W. Meadowlarks - heard Oregon Juncos in fence rows
