Mar. 15
Lake Merritt, Oakland, Alameda Co., Calif.
at 9:00 A.M. several of this species, among some
other species, were baited up to the shore about
15 feet from us. At this range the red eye was
easily seen. Their red, sloping head + white back
were also easily seen. None of them would come
up on the shore so that the legs could be
seen. Even when very near the shore so that they
could stand up in the water, they still seemed
reluctant to do so, keeping the body in the
water at all times. The female canvas-back has
a much duller colored head, but the distinctive
slope of the head was still present. The eye of
the female was almost black. The ♂ didn't seem to
be too interested in the ♀ yet.

April 2
Conaway Ranch, 2 mi. east of Woodland, Yolo Co., Calif.
An injured ♂ was seen in the company of
1 ♂ + 2 ♀ Mallard in a dirt-lined irrigation
ditch this morning. He was able to flop across
the water, but could not fly.
