Winter-ground microhabitat use by differently coloured phenotypes affects return rate in a long-distance migratory bird.

Abstract excerpt

Migratory bird populations are declining globally at alarming rates. Non-breeding site conditions affect breeding populations, but generalising non-breeding habitat conditions over large spatial regions cannot address potential fine-scale differences across landscapes or local populations. Plumage characteristics can mediate the effects of environmental conditions on individual fitness. However, whether different...
