Abstract

Factors affecting the patterns of behavior of individual Glaucous-winged Gulls (Larus glaucescens) on Protection Island, Jefferson County, Washington were examined. Males were found to be present on territory often than females. Proportions of behavior varied by time of season. Gulls tended to be more alert (used upright and intermediate-upright displays) during the "chick" stage than earlier in the season. Attendance rates were very similar between individuals of the same gender, and a significant correlation was found between the attendance rates of members of a pair. However, sequences of territorial behavior varied significantly between genders.
