Thursday June 1. Buford to Johnson. We left Buford at 7.15 for Culbertson, where we engaged a man to drive us out to Johnson Lake about 18 miles to the North. We arrived there shortly before noon, and arranged 4 traps at a ranch about a mile and a half S.W. of the lake. We are on a small creek called Stand Creek which flows into Muddy Creek which forms the eastern boundary of the Fort Peck Indian Reservation. In the afternoon we put out a line of traps and shook four birds. Took a few specimens of Merotia. A wild mallard has mated with a tame duck which the rancher calls an "English Gray Call" said to be used as a decoy. The male bird stays about the small creek which flows past the ranch and has become nearly as tame as the duck, and will stand unconcernedly while we walk past within a few feet. We found a nest of the Brewer Blackbird on the ground on a steep bank with 4 eggs. A Robin has young just from the nest. Nests of yellow warbler are just begun. Thursday June 2. Johnson Lake. Shots surviving when we awoke and it continued off and on all day sometimes heavily. We took quite a catch of Merotia, Peromyscus & Zapus, and more than 10 in the afternoon. We also shot a few birds. It was very cold and disagreeable all day.
