Aim We assessed the independent and interactive effects of land use and other factors
on regional distributions of lake shore bird assemblages.
Location Analyses were restricted to lakes of the northeastern United States (New
England, New York, New Jersey).
Methods Lake shore bird and habitat data were collected from a regional sample of 186
lakes between 1991 and 1995. Local and regional gradients in environmental attributes
of the lakes and their watersheds, and in bird species composition, were characterized
using detrended correspondence analysis. Bird assemblages were also characterized
