Howell, T.R. 1949 Journal Crowder Flat, 5200 ft., 38 mi. NNW of Alturas, Modoc Co., Calif. June 7 - Up at 3:05 A.M. again. I heard the first birds - Robins - at 3:30. At nest #1 I heard Olive-sided Flycatchers (singular?) at about 4:30 A.M. - I had seen one before, but this is the first time I heard one. The Steller Jays do not seem to get noisy until 5:00 A.M. Crossbills, I find, are very common in the area, going in flocks of 5 - 10. I fre- quently see them in the low deciduous trees in the meadows. During the day I heard lots of Olive-sided Flycatchers, which is a bit strange as I had not heard any before. At 3:45 P.M., by nest #6, I came on a Mourning Dove sitting on its nest on a flat place on a fallen yellow pine log, about 3 1/2 feet above the ground. The bird would not flush until I came within a yard of it. In the nest were two squabs sitting very quietly, about 2 1/2 inches long, dark grey skin, and almost completely covered with cream-colored down. At 6:30 P.M. I found a small rubber boa (Charina bottae) in the path just above the meadow by the ranger station. It is about 8 inches long, pinkish brown or cinnamon in color on the dorsum and more yellow ventrally. I am saving it alive. The skin is very soft and silky.
