FIELD NOTES
Doug Bell
DATE: 22 April 1986
LOCATION: BERKELEY CAMPUS, ALAMEDA CA,
CALIF.
WEATHER: RAIN
TIME: 9:30-10:00
At lawn just east of Giannini Hall, south of
University House. Observing partial albino robin.
The bird is quite tame - foraging on lawn. Was at
first within ca. 2 meters of a normal male, also foraging.
The albino then left this bird, walking, foraging. No
real interaction took place. Another male flew up in
the tree to the west of this bird. No interaction, though.
I might guess the albino to be a female. It has
a pale yellow bill. Dark iris. White/dark flecked (patchy)
head, nape, back. Most primaries & secondaries dark, but
about 2 secondaries and possible primaries 1 & 2 are white,
on each wing. Tail mostly dark, with left outermost tertials
white (2?). Right outermost tertial whiteish. Wing & tail
covers flecked white/dark. Breast and belly is white,
with rust collar (about where the dark collar of a varied thrush
would be). Very light rust patches on each flank, and
one small rust spot on center of lower breast. Throat
white. Odd looking bird - like a large snow bunting
in mixed plumage. Came to within 2 meters of the bird.
After 1/2 hour of mostly unsuccessful foraging the bird flew
labored up into a tree. Very calm bird.
TIME: 2:00-2:30 PM White-flecked robin observed foraging
again. Came very close to me. Then flew up into a tree.
About 5 other robins were in this tree, but there was
no interaction between the white robin and the others.
