Two pairs of mountain bluebirds are known to have nested near the camp on the rim during past years, but neither has been found this year. However, the activities of a pair indicate that a nest may be discovered near the Community House.
A flock of Brewer blackbirds is reported by Ranger Fisher on the rim near the Lodge.
A mating pair of golden eagles was observed southeast of Union Peak in a part of the park rarely visited.
A black-chinned hummingbird is reported from Wizard Island. An observer in the Park has stated that he has seen more humming birds in the park than he had ever seen elsewhere under similar circumstances.
Clarke's Crow. The young of this bird are now coming from their nests and the continual squalls are making the woods resounds. The fluffy fellows, as large as their parents, are common in the tourist camps. The Oregon or Grey Jays are not often seen near the rim and among the tourists the Clarke's Crow or Clarke's Nutcracker has taken the name of camp-robber.
The bird-list for the park for the past two years numbers seventy-five and many may be added.
