Clangula hyemalis
June 27 (Barrow, Alaska) ridge there were 2 flocks of old
squares. One of these flocks consisted of one
drake and 12 hens. As I neared in the
weasel the flock flew up - circled low - and
landed 150 yards farther down (in the lake).
Then they climbed up on the bank. I approached
once more but very slowly. At 50 yards the
birds moved into the water; at 30 yards, I
out the motor. Some of the hens were preening.
I watched the drake scratch his face - he did
not reach over the wing (as magpie do). A couple
of hens appeared to be feeding; they dived for
periods of 6 to 25 seconds. Couldn't see
what they were bringing up - if anything.
The drake approached a hen - (to copulate?) in
this manner: swan low and stretched out in the
[illegible]
water. The hen shook her tail and swam off.
The drake never got closer than 6-8 in from her.
The hen did not permit copulation (if that was the
intent of the ?). The drake approached a 2nd hen
in the same way and was again rebuffed. The
appearance of a limning discontinued observations.
However at 0750 I observed a pair of old squaw
Together in a small pool near the bridge at the
camp entrance. This raised the question: Why.
