Description: Information on dispersali s critical for understandingt he population dynamicso f birds. We estimated breeding and natal dispersal in two studies of a population of the Puerto Rican Vireo (Vireo latimeri) that is in danger of local extirpation due to low reproductive success from 7.1-29% of adult males and 12.5 - 25% of adult females changed territories between breeding seasons. The median breeding dispersal distance of 12 birds (7 males, 2 females, and 3 of unknowns ex) was3 70 m (range 110-560 m). Four fledglings dispersed a median distance of 490 m from their natal nests to breeding territories (range 300-2030 m).The implications of these data for population trends of the vireo in Guanica Forest are discussed.
