Canon. I saw several Canon Towhees. Will shot a Poor Will in the evening. May 19. Will and myself stayed in camp while Howard and Rising went up the canon. They brought back an Olive-backed Thrush, and another, apparently, allied to the Hermit Thrush; a Long-crested Jay, and a female Hummingbird. They found the rest of the summer but were unable to get it. Will and I after skinning our birds, walked down the canon, to look for another Poor Will that he shot last night. We did not find it, and shot nothing else. Saw two Western Robins. In the evening Riety, Will and I, tried to get some Poor Wills; We saw several and Will shot at one but did not get it. May 20. Howard and myself went over to Millie's Canon. We collected a set of Painted Redstarts, by a spring and just a few feet from the water; and nearly, a set of Ariz. Jays. On coming up over the divide at the head of the canon, we saw three pigeons in some oak trees, and I managed to kill one with the cane-gun. I also shot a male Chestnut-backed Bluebird, and an Arizona Junco. I shot at what Howard thought was a Buff-breasted Flycatcher, and at what looked to be a Melanistic Audubon's Warbler, but got neither. On the divide we saw a number of Western Robins, Nuthatches, Mexican Crecpies, Violet-green Swallows, White-throat Swifts, and Chestnut-backed Bluebirds. Saw some Audubon's Warbler
