Multicomponent shell traits are consistent with an individual recognition function of the appearance of common murre ( Uria aalge) eggs: A biological replication study
Abstract In dense breeding colonies, and despite having no nest structure, common murres (or guillemots: Uria aalge ) are still able to identify their own eggs. Each female murre's egg is thought to be recognized individually by the shell's avian‐perceivable traits. This is because the egg...
