| Abstract: | Capsule?Body mass of Whiskered Tern chicks from the central parts of subcolonies grew at a higher rate in comparison to chicks hatched in the peripheral zones. Growth rates of both body mass and head length correlated positively with nest density. We suggest that spatial distribution of pair quality within the colony of Whiskered Terns follows a central–periphery gradient. |
