Late evening a number of Poor Wills were heard calling, and one came and hovered almost over the table while we were eating. June 10. Rising went over to Carr's Canon after some nests he found some time ago, and the rest of us went up Ramsey Canon. A short distance from camp Will got a set of (?) Hummingbird, and shot the female bird. Above the box canon Howard went up a pine tree to examine a Cow's Flycatcher nest that he found. There was nothing in it, but on a limb a little above, was a nest of Buff-breasted Flycatchers, containing four eggs. He had some difficulty in getting the nest as it was pretty well out on a limb about fifty feet from the ground, but with the aid of a rope, the set was secured, and the female bird shot. The male we shot on the 8th was probably its mate. Will secured a set of Rivoli Hummingbird in the same place and shot the female bird. A nest of Black-throated Grey Warbler was found nearby, containing young. Further up the canon, Howard climbed to a Black-throated Grey Warbler that he found on May 27th, but the joys had destroyed it. He took a set of three Hepatic Tanagers, the nest of which was also found on May 27th;
