KRE Pond, Aquatic Park, Berkeley, Alameda Co., Calif.
Aug. 8 — The pond is very much dried up at
this date with a heavy layer of scummy
green vegetation covering most of the water
that is left. On one small open spot there
were 2 phalaropes, one Northern and one
Wilson (Lebipes lobatus and Steganopus tricolor)
and a Bonaparte Gull (Larus philadelphia) in
winter plumage. The Wilson Phalarope was
pursuing some sort of flying insect which
alighted in swarms over the scum and
quiet water. The phalarope was very quick
and active in its feeding, attempting both
to snatch the insects from the surface as
well as catch them as they flew off.
It seemed to be moderately successful at
catching them by both methods. The Northern
Phalarope was much less inclined to feed
on the insects, and made only an occasional
pass at them. Even the Bonaparte gull
snapped at a few as it swam about. Four
Mallards (none drake-feathered) were present,
and numerous Barn Swallows, Forster
Terns, Bonaparte Gulls (both summer +
winter plumages), Western + California
Gulls, 3 Farallon Cormorants, and 9
White Pelicans were seen soaring over
at a good height.
