Abstract: | The nest-site preferences of sympatrically breeding Adélie (Pygoscelis adeliae), Chinstrap (P. antarctica) and Gentoo (P. papua) penguins were quantified in rookeries at Point Thomas, South Shetland Islands. Adélies nested in larger, denser, more open colonies, at higher elevations and farther from landing beaches than those of its congeners. Chinstraps nested in steeply sloped areas; Adélies and gentoos nested generally in flat and gently sloped areas. It is suggested that differences in pygoscelid nest-site preferences may be partially attributable to differences in the degree of coloniality evident in each species. |
