Phenotypic and environmental correlates of natal dispersal in a long-lived territorial vulture
Abstract Natal dispersal, the movement between the birth and the first breeding site, has been rarely studied in long-lived territorial birds with a long-lasting pre-breeding stage. Here we benefited from the long-term monitoring programs of six populations of Egyptian vultures (Neophron percnopteru...
