Pintail - 25 or 30 pairs scattered over the area, and some in a flock of 24 - 30 or so. Green-winged Teal - few scattered pairs, and many in pretty large flocks yet. A total of about 350 birds were seen. Cinnamon Teal - one male seen with [illegible] wings at north end. At south end, we saw a female or immature that could be either this species, or the Blue-winged Teal. Shovellers - about equally divided sexes. about 50-75 birds in the area, many appeared to be paired up.

Marsh Hawk - pair over field just north of the swamp. Osprey - one down in sedges at south end. flushed with three sharp "jeep" 's and flew south a little before climbing. Dave and I were both fooled on it #or a while ! Sparrow Hawks - over damp pasture area on east side. Pheasants - crowing, especially when any blasting, near or far, took place. Virginia Rail - seem to be quite a few in the area. I'd estimate at least 10 pairs, and I'm sure we didn't hear or see them all. Nest begun last week still in same condition. Found another nest, near the cabin, in Carex obnupta. Plant material still wet. About 8" over water. Cup 3" deep and 4-5" in diameter. At NW corner we found a grass platform about 3 feet up in small ash, in Carex clump, which we can't figure out, unless it is a base for this species. (strikethrough)over too! Coots - still present in numbers, and small flocks - about 100 I'd say. Killdeer in wet pasture on east side. Greater Yellow-legs - 3 at usual place near horse barn.

Cliff Swallows - same habits, but not too many seen. Low over water, and fields. Purple Martin - Dave kept hearing them, and I thought I spotted a couple early in the p.m. but we didn't prove this till about 330 p.m., when one dropped down plenty low, from the very high altitude they had been circling and feeding on. Ravens - 3 flew over swamp. W. Crow - 2 in tree at south end, at edge of pasture area, others heard calling. Bush Tit - a single one in a brush clump, on south island, in pasture area.
