February 4, 1947, 12-mile Swamp, Bruce, Benton Co. 130 to 430 p.m. ½F 300Brkn, 7000 Ovc. SW 4. 40°F. Blue Heron - one flushed from the ash at the north end. Lesser Canada Geese - approx. 1500 flushed from a field south of the swamp, when we were still 200-250 yards away, but all flew over us, as they flew to the north end, where we flushed them about a hour later. It was a thrill to see them in flight, and still more of a thrill to hear the crescendo-like roar at the beginning of the flock taking to the air. Mallards - perhaps 40 were seen altogether, about equal M & F as we could tell. Pintails - two flights of 70 and 50 went over us at the south end, and then we flushed about 200 more at the north end of the swamp, and these left the swamp area altogether. Green-winged Teal - between 2 and 300 were seen in the grass and shallow water at the norhend of the swamp. There has been a decided reduction in the number of this species the past couple of weeks. W. Red-tail Hawk - a pair flew over the swamp, but did not see them pursuing prey. Sparrow Hawk - just one seen on a wire line a mile or so N of the swamp on hiway. Coots - The population doesn't seem to vary much, for there are about 100 yet. Wilson Snipe - just one pair flushed from a flooded pasture near the swamp. Flickers - some along the fence row and fields on the way in. Horned Larks - heard one singing, several calling, and a few flew over us. Tree Swallows - Dave and I watched one feeding continuously over the central part of the swamp, and saw its field marks many times during the course of the afternoon. When we went to the far north end of the swamp, we saw one there, which may well have been the same individual, altho, all the time we were at the south end, it was seen there. W. Crow - some heard in the distance. Oregon Chickadees - in the ash at the edge of the swamp. Seattle Wren - heard one or two, and they were singing each time. Tule Wren - heard plenty of them, and saw a few at very close range. Robin - three or four seen at the swamp. Wb Western Bluebirds - adults and immatures were very common everywhere around, the swamp, and we found one flock "hawking" in company with Audubon Warblers, over a flooded area of pasture. Call notes were heard constantly, and once we though that we heard one starting to sing. Ruby-crowned Kinglet - a few in the brush. Northwestern Shrike - the first thing that greeted us when we neared the bend in the road at the swamp was a view of an immature Shrike, presumably of this species. It flashed so much white in the wings and in the outer tail feathers that our first thought was of a Mockingbird. The black wings and slightly hooked bill soon dispelled that hope. The general body color was a dark gray, lighter below, but not white, as on the adults. It perched in low trees, and on fence posts, and gave chase to passing insects, and when we first saw it, went to the gravel in the road several times. 15 minutes later it did the same thing, while under fire from my "wide-of-the mark" Bee Bee gun. Sorry, I couldn't collect it. Pipits - heard quite a few and a flock or two of 8 or 10 birds flew over. Audubon Warblers - perhaps about 100 of them working through the ash, and on the brush and grass in flooded pasture areas. One group of them was work- ing through a flooded pasture in company with Western Bluebirds. W. Meadowlarks - a few seen and heard. Northwestern Redwings - when we first hit the swamp, there were none to be seen or heard, , but about 3 p.m., the first ones arrived, and by the time we left, the stragglers may have amounted to over 100 birds in the area. Brewer's Blackbirds - a few flew over singly and in small groups. Savannah Sparrow - at least 2 and probably more seen in fields on road into the swamp. Gave call notes from the grass, or small trees wherever they were Towhee - pairs seen over more or less equally divided areas around the swamp. Juncos - small groups seemed to be working the brush everywhere. Golden-crowned Sparrows - about 6 of them feeding in the mud at the edge of pool. Song Sparrow - in all the fence rows, and with the Tule Wrens and Towhees around The swamp.
