McFadden's Swamp: Benton Co., Oregon - T.A. McAllister January 27, 1949. 16:30 to 17:45 30°, light north wind, overcast sky. Fields and swamp completely frozen except for a few spots in the main channel of the swamp south of the bridge. Whistling Swan - 1 adult bird in open water south of bridge. Canada Geese - all over in the rye fields on the southeast, corner. When nearly dark, they began pouring into the small area of open water on Muddy Cr. just at the south end of the island. Only several thousand birds. Mallard - just at dusk the ducks came roaring in to this tiny area from all directions. Temperatures this past week have ranged down to 18°, and even this small section had ice all around its borders. Apparently the numbers and actions of the birds have helped keep it ice free. About 500 Mallards; the commonest duck. Pintail - 50 also came in at dusk. Baldpate - Shortly after dark a large flock came in, but it was too dark and I could tell them by call only. Green-winged Teal - just a sprinkling of teal mixed in with the other ducks, about 20 all told. Ring-necked Pheasant - 3 m. in fields Coot - a few on the open water, but 8 noted out in the open fields feeding. Tried running them down, and they don't have the least difficulty taking off land. Great-horned Owl - 1 calling from ashes in swamp. Red-shafted Flicker - 1 very tame bird apparently starved feeding poking for insects in frozen ground. Bush Tits - small flock Varied Thrush - a few in the ashes Pipits - many large flocks noted feeding along the roadside north of Ben Bruce Station. McFadden's Swamp; Benton Co., Oregon January 30, 1949. 16:30 to 18:00 Just above freezing, stiff north wind, and clearing rapidly. Fields and swamp thawing, but still covered with ice. Spent the whole evening in a small blind at the south end of the island. Whistling Swan - At dusk three adults circled in and lit at the edge of the water directly in front of our blind. The only sound they made was the loud rattling roar of the wind in their flight pinions as they landed. They spent their time feeding and preening. When it was dark, we stepped quietly out in front of them, but they were not the least bit disturbed; neither was a flock of nearby Canada Geese. Only the mallard became alarmed. Canada Geese - At dusk four lone geese came over and circled the area many times, and then after setting up a wild, clamorous call, settled down. Shortly after this the
