June 18, 1948, 12-mile Swamp, 1215-1330, 30 /, NE 2-6, 75-78°F.
Blue Herons - several in area
Mallards - a few females flushed - no males seen.
Wood Ducks - one full male in spike-rush area, and in south end I flushed a family that had from 10-13 young, 1/3 grown - ran very fast on HOH
Hooded Merganser - flushed one immature or female.
Vultures - at least 15 seen over the swamp area.
Cooper Hawk - one circling with the vultures
Valley Quail calling
Pheasant - flushed pair adults and about 11 chicks that were 4-5" high.
Coots - none seen
Killdeer - 2 flew over Mourning Dove - 1 adult - young already gone
Little Flycatchers - in water-killed ash areas.
Horned Larks - singing from fields Crows heard
Raven - just one flew over
Tule Wrens - singing everywhere - mostly young birds -
Coots - Robin - a few
Cedar Waxwings - quite a few feeding over the water from thewaterkilled ash
Lutescent Warbler - heard just one
Yellow-throats - quite a few calling.
Meadowlark on grass island at south end.
Redwings plentiful. Area full of young birds. Second nestings really under way with many new nests, mostly in spirea and ash - the first nests are usually built in Carex obnupta, before these 2 shrubs leaf out. I banded 5 more nestlings, and there are 8 or so too young to band yet. I watched adults catching large dragonflies - Libellulids to take to the nestlings..
Brewer Blackbird - a few flew over
Willow Goldfinch - a pair seen
Vesper Sparrow in field along east side of swamp.
Song Sparrows - everywhere - many immatures present.
June 20, 1948, Avery Park, 1300, 15 Ovc RW-, SW -2-8.
Silver Pheasant female on new nest just 14" south of previous nesting, of which there was nothing left but a few pieces of broken egg shell! Hatched or eaten??? She was reticent to leave the nest, for it was cool, and I patted her head before she did. She uttered low, guttural chortles all the while. There were 6 eggs in the nest. Nest abandoned by June 30th. 6 eggs still intact.
Juncos - adults feeding nearly full-grown young that were brownish and light barred on the wings.
