Sparrows. In the afternoon we saw a few Goldfinches (Arkansas?) near the camp. In the afternoon it rained very hard. June 27. Howard went up the canon collecting, and the rest of us stayed in camp, skinning birds, etc. Howard found a nest of Virginia Warblers, and one of Poor Will, each containing young. We shot one Broad-tail, and four Black-chinned Hummers, a Painted Redstart, an Olivaceous Flycatcher, and a Virginia's Warbler. June 28. Will and I went to the divide and as far as Miller's Canon on its divide, and returned by way of the Wisconsin Gulch. I found a nest of the Olivaceous Flycatcher, containing young. The nest was in a hole in a small tree, about 15-feet from the ground. It was right next to the trail, where we passed it almost every day, and yet we never even saw the birds. I also found a nest of Criz. Junco containing young, and one containing two incubated eggs. On the divide we saw a good many Grace's Warblers, and shot three, which were apparently breeding. We shot an Olive Warbler which was evidently nesting, but we did not find its nest. We also shot two Criz. Junco, a Blackbird, Vireo, a Song-crested Jay, a Chestnut-backed Pileated, and a Band-tailed Pigeon. The Pigeon we shot was a female with a well developed egg in its ovary. We saw a good many Pigeons
