This study examines relationships between natal dispersal and intrasexual competition, the mating system, inbreeding, inheritance and social status in five cohorts of song sparrows, Melospiza melodia, resident on Mandarte Island, B.C., Canada. The role of natal dispersal in population regulation is also considered. Several hypotheses of natal dispersal were tested with experimental and observational data. Dispersal distances were similar among the sexes, but distances depended strongly on point… CONTINUE READING
