a short time - until she spied the uphill ternaron again,
which was watching them from on top of a rock about
15 yds away. She chased it away and returned.
During subsequent feeding of several minutes, the
ternelle frequently ran from the rock, who threatened her
when she got too close. Then both ternarons
for some reason (perhaps he chasing her away?)
rone chased up hill for at least 20 yds and were
lost to men for a few minutes. One, however, soon
started calling from on top of a rock. Started with
the mellow, natural call, then gradually changed to the
sharp call. I think this was the red one, but it may
have been the uphill bird. It was soon answered
repeatedly by the q, who was downhill some 30 or
to yds. After several minutes of calling, the rock bird
jumped down into the grass and took out of sight, calling
only occasionally. After 5 minutes, the red one
squealed and flew from uphill to about about 30
yds above the nest. He may have flown voluntarily or
been pursued by the uphill bird. The q was still
calling about 40 yds beyond the nest. He walked
to the nest in about 20 minutes, worked a few feathers,
sat down, called once, then was quiet (5:40).
The q continued to call and moved about not being
looking for someone. At one time she passed 15 yds
from the or drumming but paid no attention, when
a bird (the bird?) uphill started calling she
moved quickly up towards it, finally came, and
