Little Gull Overview, All About Birds, Cornell Lab of Ornithology

The first record of Little Gull in North America was in 1819, but the first nest was not discovered until 1962. After that time, numbers increased and sightings became more frequent. Whether the species had always been present in small numbers or if it newly colonized the continent in the 1960s is unknown.

In North America the Little Gull is most frequently observed during winter and on migration in groups of one to three, usually associated with larger flocks of Bonaparte's Gulls.
