Howell, T.R. 1949 S.v. daggetti 81 Crowder Flat 5200 ft. 38 mi. NNW of Alturas, Modoc Co., Calif. June 12 (cont'd.) - There seems to be little deviation in the pattern of care of young in any of the pairs. All during the day food is brought at least every 10 minutes, usually every 7, or oftener. There are no apparent slack or hyperactive periods. Possibly nest sanitation is carried out largely by one of the pair, perhaps the F. More or less stereotyped behavior and pathways to the nest are the rule. Much flycatching is done. The watching is extremely boring as there is so little variation of activity.
