McFadden's Swamp, 1 1/2 miles south of Corvallis, Oregon April 8, 1949 7:00pm to 9:00 pm. Observers : McKlisters and Marshalls Water level: h Only puddles and soggy ground in north field. Weather - Clear, still, temp 50 to 60. 3/4 moon. Quite light out. We thought we would see how the swamp looked at night and see how the birds acted. Started trip out by climbing on the tower at the RR tracks to watch the geese. Then walked along the east side of the main pond to the north field and [illegible] then along the fence line between the north field and pond to the swamp outlet and up in the trees to the far [illegible] west corner, back across the north field to the main pond. Walked down the main pond through the water a ways and then back to the car. [illegible]. We found that the waterbirds acted no dif- frent than if it was daylight. Blue Heron - at least two. Flushed one in the dark from the swamp. Could not see him but heard him squak. Canada goose - About 200 in the fields east of the north field. From the tower we saw several small groups of about 20 leave this flock and circle around out over the Willanette and down the river until out of sight. This was between 7:00 and 7:15 [illegible] at dusk. The remainder of the flock stayed and cackled often on all the time until we left. [illegible]. In the rye grass field there was another flock of about 200. [illegible] These apparently stayed there. With them was one. Snow Goose - see above. Mallard - By the time we left the tower it was too dark to see any ducks, but we heard mallards quack all through our stay. In walked down through [illegible] the main pond, we flushed what seemed to be large flocks but could not see them in the dark. Green-winged Teal - Heard a few call. Ring-necked Pheasant - Heard some docks crow. Killdeer - heard some around 7:30 Wilson's Snipe - Flushed snipes from the SE 1/4th of the north field steadily. I would judge there were over 20 of them. We could not see them, but the squaked and flew up as though it was daylight. We tried using a flashlight to blind some, but it was apparently too bright on account of the moonlight. Greater Yellow-legs - 28 or more in flooded field where the road first turns at the swamp. We watched them until dark, and then came back about 8:30, but could not [illegible] raise them by walking across the field. Western Sandpiper - Flushed about 30 of them about 7:30 at the same place as above. Horned Lark - The fields were alive with their songs between 7 and 7:30. Also a couple in the road. Yellow-throat - One singing. Red-wings - Heard them singing while on the tower. LOWER CAMPUS, OREGON STATE COLLEGE , CORVALLIS April 8, 1949 9:00am to 9:30am.
