Logopus lagopus
25 May About
with the ripping flight and glide
and the cockle left their tones
did not seem to be defended.
There seemed to be some
interaction going on between
the willow and rock ptarmigan
(3 or 4 of latter in the
same area). Once when a
willow ptarmigan flew and
displayed at the end, a rock
ptarmigan got up and flew
towards the willow. Later, a
rock ptarmigan flew to a conspicuous
roof on the right limit of
the creek - granite ridge - soon a
willow ptarmigan flew down
the creek and landed in display
flight about 10 yds from that
spot. The latter took
off and flew over the ridge.
28 May
Ptarmigan - two males were seen
in the creek bottom ca 1 mile
inland from the view. Again they
were in close proximity to limitus
and there appeared to be some display
between the two forms.
