Objective(s): To determine the importance of gull and jaeger predation to the nesting success of brant and snow geese at Anderson River; to test the importance of colonial nesting by geese as an antipredator strategy; to determine why snow geese are less susceptible to avian predators; to study the foraging strategies of glaucous gulls that nest amongst the geese at Anderson River.
Project Description: This study will entail observing glaucous gulls as they prey on nesting black brant and lesser snow geese. The researcher will attempt to determine why the gulls seem to be more successful when attacking brant nests than snow geese. No birds will be killed or removed during this study.
