Abstract

Arthropod population densities were evaluated from nests of colonial ring-billed gulls (Larus delawarensis). Each nest was considered as being an island microhabitat in which a measurable population was concentrated. Despite significantly greater numbers of arthropods in larger than in smaller gull nests, population densities per nest dry weight were similar.
