Howell, T.R. 1949 Journal Crowder Flat, 5200 ft., 38 mi. NNW of Alturas, Modoc Co., Calif. June 5. Weather clear, warm, windy at times. A new bird from the area noted today is the Nighthawk (Chordeiles minor), which I heard in the morning and later saw in the afternoon - 3 birds over Crowder Flat, very high up. While looking for more sapsucker nests near #6, I looked into a hole 4 ft up in a dead aspen. A sort of hissing, thumping noise began immediately and gray dust came rising out of the hole. This proved to be the doing of a Mt. Chickadee which remained on the nest. It seemed to be raising and lowering itself with some wing motion as well. See today's saps. species account for notes on a House Wren chasing a chipmunk. June 6 - up at 3:05 A.M., faint signs of dawn in east - clear with a few small clouds. At 3:20 I heard Chipping Sparrows singing, and by 3:45 most of the passerines were singing or calling - Juncos, Robins, Vireos, Warblers, Sparrows, Blackbirds, Flycatchers. At 3:45 at the Willow Creek Meadow I heard a Poor-will for the first time; it was getting pretty light by then. No woodpeckers were heard until a little after 4:00 A.M. At 8:00 A.M. I went out with Drake
