MCFADDEN'S SWAMP, 14 miles south of CORVALLIS, BENTON CO., ORE.
January 25, 1949 14:00 to 17:00
Weather - temp 23 F, clear later changing to high clouds. Ground covered with one inch of snow. Ponds completely frozen over except for a small portion at the south end and a small portion east of the island at the north. Muddy Creek frozen over !
Coverage - Walked to both ends of the swamp.
Whistling Swan - Saw the 7 again at the same location as last week. The called for us and gave us some good views. Very tame. Some of their calls were almost human-like. In addition to those given last time, the birds gave low whistles. They again pumped their heads up and down, calling while doing so. Belive now that I was mistaken before in seeing an immature. I am sure there were no more than 7 present today, all adults.
Canada Goose - 2,000 to 2,500. A few cacklers.
Mallard - Saw only 6.
Baldpate - A flock of 20 alighted beside the swans, but soon saw us hiding in the ash and took off again.
Pintail - About 25, 20 in one flock. Sexes 50-50.
Ruddy Duck - 5 around the island at the norht.
Coot - About 200. Always a small group around the swans. Wonder if the swans don't bring up food for them.
Tule Wren - Saw tule wrens several times around the beaver house and dam north of the island.
Varied Thrush - one almost the same ash as last week.
Pipit - Several flew over.
Audubon Warbler - one near the RR tracks.
Red-wings - Began coming in about 4:00 pm. Probably 100 present when we left.
Fox Sparrow - One inside the horse shed scratching for insect larvae slong with song sparrows in the straw.
Song Sparrow - one plug four in and around the horse shed. One in the horse shed showed no concern over our presence only 4 feet away.
Fresh beaver cuttings around the beaver house. The beavers have been cutting small willows. Fresh sawdust on the ice beside their cuttings.
Highway between CORVALLIS AND SWAMP same day.
Lots of birds on the shoulders and on the pavement. Why? Heat from reflection from the sun? Pavement and shoulders bare of snow, but so were areas under trees and brush.
Sparrow Hawk - one in the usual place
Ring-necked Pheasant - one male on highway shoulder
Flicker - several, picked up one dead. May be to damaged for a specimen. Yellow-shafted-Red-shafted hybrid. Had been eating poison oak berries.
Pipit - Wish I had of startiKX'd counting pipits. Along the road in small flocks all the way, esp. on shoulders.
Brewer's Blackbird - flock of 25 and one dead one.
W.Meadowlark - Several small flocks. On shoulders again
Juncos - about 10 in one flock.
Ore. Towhee - several
Song Sparrow - Here and there. one dead one, too far gone for a specimen.
*Later - Have skinned/stuffed the above flicker. Sossed it in the car, and failed to observe that it until I picked it up again, that this flicker is a hybrid. Has red crescent on back of nitch, Red & Black mustaches. Underside of wing and tail feather mostly yellow. Sex undetermined. Couldn't find lister or ovaries.
