July 18, 1947 - MacDonald Forest, 3 p.m. Little Flycatcher - Found a nest in ad. Firs at 18' on a NNE slope in rather deep woods, some 150' from a creek. July 20, 1947 12-mile Swamp, Bruce Station, Benton Co, 430-645 p.m. Clear and warm, with Donna. Pied-billed Grebe - one came up with 50' of us and swam zigzagging and slowly toward us as we stood on the bridge across the swamp; finally diving and swimming up a ditch, perhaps towards the nest. Blue Heron - only one 2/3 grown immature bird was seen in the south end. It flew from the swamp and lit in a small ash about 100 yards away. Anthony Green Heron - one adult flushed and flew into a grove of ash, and I thoroughly searched the clump for signs of a nest, but with no success. Mallards - flushed a couple of hens. Wood Ducks - flushed one immature male, an adult female, and also 4 others. Sharp-shinned Hawk - one flew over the swamp twice, chased by groups of Redwings. Marsh Hawk - female flew leisurely over the south end. Bobwhite - heard them calling most of the late part of the afternoon. Valley Quail - saw two of them, and heard others around the swamp. Virginia Rail - heard just one Killdeer - a couple of singles flew over the swamp. Mourning Doves - 2 pair were seen during the p.m. Kingfisher - a pair of them were around the west side of the swamp, and we watched them chase each other, hover together, and fly off; the male later returning and trying to catch fish from a perch 10 feet up in a small ash. Violet-green Swallows - a few adults and quite a few young in the area. Tree Swallows - a few adults and many young were seen flying at the edge of the swamp where they could perch in the ash tree tops often. Barn Swallows - adults and immatures common over the water, and dipping in it for drinks. Several perched on a wire fence over the water. Cliff Swallows - a few adults and quite a few young feeding high, and dipping down occasionally into the water. Several young perched in ash tree tops. W. Crow - heard and saw just one. Oregon Chickadees - a few heard Slender-billed Nuthatch - 2 adults and a couple of young working dying ash trees at the edge of the swamp. Tule Wren - heard several scolding, and others singing here and there over the swamp. Robin - a few seen. Russet-backed Thrush - heard in the thickets along the creek. Cedar Waxwings - quite a few in a small flock in the ash tree tops. Pacific Yellowthroats - a few seen, and several calling or singing here and there. W. Meadowlark - singing. Yellow-headed Blackbird - one adult male seen flying from south to north across the swamp road, and it headed towards a large flock of Redwings - sometimes scattered over relatively small areas of the swamp, and other times in large flocks of 50 to 250 birds, in the swamp, and a nearby field. Flocks composed mostly of females and immatures, although there were some adult males. Evidently this flocking habit persists at the close of the nesting season. Brewer Blackbirds - a few Purple Finches - immatures seen in tops of ash trees, softly warbling, and also chasing Willow Goldfinch - one male perched on a fence wire over water. Song Sparrows - in the fence rows around the swamp.
