Howell, T.R. 1949 S.v. daggetti Crowder Flat, 5200 ft, 38 mi. NNW of Alturas, Modoc Co, Calif. June 30 (cont'd) 7:40 P.M. at #12- tapping- cries of young, head out (adult?) drawn back, 7:43. Head out sporadically for next 1/2 min - I can't tell whether adult or young; I am sure of a young once, and almost sure of an adult other times. 7:50 tapping, then silence. 7:55 last burst of faint cries from young, 8:15 P.M.- too dark at nest to see; I leave. I forgot to mention that when I looked in nest #3 I could see light from a slit or crack to the right side. Possibly this serves as an air vent, but I don't remember seeing such in the other nests. The fact that a young bird was vigorously attacked by both parents at #6 is a fairly sure sign that it was not one of theirs even though it was so close to their nest. This shows the futility of trying to be certain of the source of a young bird by its position It is possible that some young came out of #6 today, but I don't think so. Some are sure to come out tomorrow, judging by their actions today. Unfortunately there is no way of counting the young other than going in the nest after them before they leave. Since they seem to depart over a period of two days, possibly even three, the only way to count them as they came out would be to watch the nest every moment of the two days, which is im- possible for one person. The young can easily fly out of sight as soon as they come out. July 1 - 4:00 A.M.- at #6- young cheeping; still too dark right at nest to see. Tattoos heard in the direction of the former- nest #3, other-birds noisy.
