Description: We studied microhabitat use, foraging and social behavior of Broad-billed (Todus subulatus)a nd Narrow-billed (T. angustirostrisT) odies in two areaso f sympatry in the Cordillera Central of the Dominican Republic. Solitary Broad-billed and Narrow-billed Todies occupied distinct microhabitats in both shade coffee plantations and native pine forest while generally sharing similar foraging strategies. In both habitats, Broad-billed Todies foraged higher in the vegetation and occurred in more outer horizontal positions with lower foliage density than did their congener. Movement rates and feeding rates differed significantly between the two species, with the Narrow-bill being the more active species. Changes in foraging behavior by both species of todies were observed when they associated with mixed-species flocks in pine forest. We noted a decrease in some measures of spatial
