 abstract={As the breeding season progresses, the rhythmic periods of the little auks' presence and absence in a colony are subject to a gradual shortening (from several days to 24 h). The breeding season stage, behaviour of little auks and gulls, meteorological conditions and variation in zooplankton availability may exert an influence on the maximum number of little auks present in a colony during successive periods, as well as on the time of the day at which the peak numbers occur. There does not exist one superior lactor responsible for the attendance rhythm of the little auks. This rhythm is governed by the resultant of many intra-population, biocoenotic and environmental factors whose intensity of action varies with the breeding season stages.},
