h.m.nodorus scolopareus
23 June Meade River Coal Mine, 157025'W, 70929'N, Alaska
and in a hunched posture
closed just the 28's off
6-10 feet then closed to
7 over a distance of 8 to 10
feet. No copulation pressure
this, the two birds feeding close to each other.
I stopped writing to make notes at this point, and then,
within 5 to 10 seconds the males had hurried to the f.
On three occasions when I flushed this group
trying to get close, the flock got up and landed
about 10 to 30 feet off. When the f. associated
with any other
male, many "his" f. away so that none were within 10 feet
of the f. (One copulation was seen after the birds had
flushed the first time.). The impression that the f.
was defending a f. in the group was unmistakable.
One short song flight seen by an unnamed f. included
a song like the "peet-cep," song - "plee delada leb" -
and given from about 8 feet up, the wings open but flat
and the head lowered below the body level; then,
its song, raised slightly above otherwise, as in
normal flight.
