R.E. Johnson 1967 43 Journal June 28 Garfield Peak to Vidale Ridge, Crater Lake Nat. Park, Oregon (cont.) lower limb chirping & disappeared (probably flew off). Shortly a bird (same?) approached the same area & landed to feed at a snow margin where I collected it at 10:30AM (♂). (rosy finch) Another bird was observed hopping from upright limb tip to limb tip pecking at needles. There were numerous insects flying around it but it did not flycatch. (rosy finches) Two birds were observed at 11:15AM on the cliffs on the no. face of Applegate Pk. They were facing each other with bodies very erect & breast out. The one most conspicuously in this posture flew up, hovered over the other & relanded. It then flew down from the rock to a lower spot with its wings partly spread & tail up at 45°. The behavior of the two birds suggested both hostility & mating. It appeared that the displaying bird was chased prior to the display. Both birds gradually moved down the cliffs, always the same bird leading & occasionally displaying. No sounds heard, but the birds were considerable distance away. (rosy Finch) a bird flew up from the no. face rim cliff face and lit in a tree, then flew to another & sang high inquiring (uprising) chirps; then suddenly a rapid series of hoarse chirps with a higher overtone as if excited. It then flew to the ground to feed.
