Description
Summary:A conspicuous but incompletely studied activity of breeding Ancient Murrelets (Synthliboramphus antiquus) is the gradual increase in the number of individuals on the sea near the colonies from mid- to late afternoon until darkness each day during the breeding season. Ancient Murrelets fly from the foraging area to the "staging area" or "gathering ground" adjacent to the breeding colony, and spend up to several hours each day for more than 2 months each year engaging in social activities, possibly strengthening pair bonds and prospecting for mates. Here, Sealy discuss the breeding status of ancient murrelets attending gathering grounds near Langara Island in British Columbia.
