in some bushes. I secured it and found it was an adult male Red-faced Warbler, the first we had seen. We shot five more during the day. Painted Redstarts were fairly common. We saw a number of Aziz. Jays but as we got higher up in the mountains they became less and less common, and we saw more of the Song crested. Saw some Band-tailed Pigeons, a good many Bridled Chickadees, Pygmy Nuthatches and Townsend's Solitaire. Many of these birds seem to be migrating. We saw many Town- send's Warblers, but all were males. In one place we flushed a pair of Stephen's Whip-poor-wills out of the bushes but did not get a shot at them. Shot several Arizona Junco's and one Grey Headed. In the afternoon, while we were skimming birds we heard a bird close by, the note of which we did not recognize. After some trouble Rising secured it, and it turned out to be a Cores Flycatcher; a few minutes after, he shot another. The note was very similar to the Olive-sided Flycatcher. Apr. 28. Today we shot a number of Townsend's Warblers, all males, a Western Warbler, a Red-faced, and a Grace's Warbler, the first we have seen. Will went off alone and came back with a set of Painted Redstarts, but the birds of this kind do not seem to be breeding here yet. Apr. 29. Today we saw a great many Townsend's Warblers, the bulk of them being females, the first we have seen. Shot a male Hepatic Tanager, a Hammond's Flycatcher, and a Flammulated Screech Owl. I saw a pair of Bower's Sparrow which were evidently breeding but I could not find the nest.
