June 28 Garfield Ph to Vidoe Ridge, Crater Lake Nat. Park (cont.)
individuals were retrieved. The q was lying face
down on a relatively level spot & may have suggested
a crouching q. A third male Rosy Finch of this
group was then collected. The above situation
suggests that the activities observed on the face
of Dyar Rock on June 26 involving falling dead
or dying birds may(?) also be explained in terms of
copulation & associated displays. A dead bird facing
downward, even though a male, elicited a similar
defense by another male even though no copulation
took place. The falling fluttering bird may have
suggested some portion of the q mating display
since the other male followed closely with evident
interest.
Near this same spot, a Fox, 2 Deer, &
a Red-breasted Nuthatch were seen prior to 10AM.
The beaks of the 2 or Rosy Finches (above - collected)
were muddy.
A Rosy Finch chirped from a White-bark Pine tree
top overlooking meadows. It then sat quietly looking
about. Twice it pecked at the needles on which it
was perched. I Clarke Nutcracker approached &
landed on the same perch. The Rosy Finch flew off
before the Nutcracker landed. It flew 100 yds &
lit in another tree top where it sat quietly, changed
perches once, pecked at the needles several times &
then preened for several minutes. It then flew to a
