Abstract
The objectives of this study were to determine the effects of habitat, time of day and tide on the behavior of Glaucous-winged gulls nesting on Protection Island, Jefferson County, Washington. During the period of March - June, 1991, more gulls were present in the colony and their rates of behavior were greater during the morning and evening hours than during midday.
Though gull numbers and their rates of behavior in the colony tended to increase with tidal cycle, a plateau in these numbers and rates consistently occurred between +0.3m to +1.2m above mean tide.
More intrusion and courtship-related activity occurred in the short habitat than in the medium habitat, even though the nest density and reproductive success were not significantly different.
