Abstract
Abstract We evaluated breeding season (May–July) bird species richness, abundance, and diversity in 21 restored wetlands and several associated habitats (woodlots, cultivated and uncultivated fields, and hedgerows) on Maryland's Eastern Shore over two years. Ninety-seven bird species were encountered over all habitats, while 72 of these species were found in wetlands. Of those birds found in wetlands, 35 species (49%) were wetland dependent and 13 species (18%) were breeding. Wetland-dependent, shorebird, and total species richness and bird abundance were lowest in fields and highest in restored wetlands. Total avian abundance and species richness in woodlots were similar to values in restored wetlands, but species composition differed. The density of individuals and of species was highest in hedgerows and restored wetlands. Bird abundance, species richness, and diversity were higher in restored wetlands in the second year of the study. Richness showed no regression relationship (p > 0.05) with either sit...
