Establishment of territories in two species of gull on Walney Island, Cumbria

Abstract

This study found that vegetation types were important in determining nesting dispersion of two closely related gulls on Walney Island: Lesser Black-backs preferred to nest among vegetation, while Herring Gulls preferred more open areas. The authors further consider the implications of this for nest spacing and related levels of aggression between neighbouring pairs. © 1980 Taylor & Francis Group, LLC.
