June 24. Howard and myself went up the canion. We collected the set of Rivoli Hummers that I found on the 16th, and shot the female. We saw five Rivoli Hummers, all females except one immature male which is the most we have yet seen in one day. We shot two Bridled Tit's and a Painted Redstart. Rising shot a Canion Towhee, and three Baird Wrens, an adult female and her immature. June 25. Will and Rising went to Fairbanks after supplies. Howard and I stayed in camp and did no collecting, but while after wood, found a nest of Hepatic Tanagers containing young. Also found a nest of Lead-colored Bush-tit, directly in back of the tail and almost touching it. I can't imagine why we have failed to find it. Howard shot a male Tanager and took a set of Chats near the camp. The chats come continually in the camp and eat the shells of any broken eggs we may have thrown away. June 26. We did not do any collecting today, except that in the afternoon we saw a set of Cassini's Kingbirds that Howard had found building and shot the female bird. Also found a nest of Scott's Oriole containing young in a scrubby oak tree. The others returned from Fairbanks with a set of Palmer's Thrasher. They shot three Sealed Quail, two Western Nighthawks, a Canion Towhee, and three Black-throated
