Orr 1932 SW slope Cuddy Mtn., 4600 ft., Washington Co., Idaho. June 30, 1932 The openings in the bank were from 2" to 4" or 5" in diam- eter and extended usually straight into the bank for from 12" to 20". The inner portion of the cavity was lined in most cases with a small amount of grass and feathers of other birds. The number of young varied from 5 to 6 per nest. Before we came close they were out at the very end of the tunnels, but when approached they would back up, keeping their heads towards the front. When taken from a hole the young birds would not go back when placed in the cavities. They would fly off, apparently able to balance themselves in the air, although not as ably as the adults. The adults after being scared away flew up and down the river, uttering a call similar to Rough-winged Swallows. Two Night Herons were seen along the river. Eastern Kingbirds were seen near Weiser, not being as abundant however as the Arkansas Kingbird. A nest of the latter was noted on a telephone pole. From Weiser we went NW to Cuddy Mountain, camping above the old tours of Heath, 1 mi. above Brownlee Ranger Station. I set out ½ doz. mouse traps about camp at 10 p.m. July 1, 1932 Caught 2 Peromyscus maniculatus in the 6 mouse traps last night. Olive-backed Thrushes heard sing- along the E. fork of Brownlee Creek among the Willows, Alders and other riparian growth. Shot one at
