Natal and breeding dispersal of Canada geese Branta canadensis
Natal dispersal in Canada Geese Branta canadensis breeding in the English midlands is male‐biased; males are more likely to change sites between birth and breeding, and move greater distances when they do so. Breeding dispersal is confined to within‐site movements, and the evidence for a sex bias is...

Summary: | Natal dispersal in Canada Geese Branta canadensis breeding in the English midlands is male‐biased; males are more likely to change sites between birth and breeding, and move greater distances when they do so. Breeding dispersal is confined to within‐site movements, and the evidence for a sex bias is equivocal. It is suggested that the ability to exploit information on brood rearing areas may be an important selection pressure favouring female philopatry in wildfowl. |
