ABSTRACT.--We investigated the relationship between habitat and landscape characteristics and the abundance and species richness of breeding birds in 12 southern Rhode Island red maple (Acer rubrum) swamps of varying size (0.5-19.2 ha). Swamp size was the most important landscape variable explaining variation in species richness for the entire bird community and for individual habitat use groups (forest interior, interior-edge, and edge species). Richness increased log linearly with size. Increased richness appeared to be due to increased habitat ...
