Sex differences in razorbill Alca torda parent-offspring vocal recognition

Razorbill (Alca torda) Science Article 9

abstract

We investigated differences in parent-offspring vocal recognition between males and females in a natural population of razorbills Alca torda, a long-lived and highly social species of auk (Family: Alcidae). Razorbills provide biparental care to their chicks while at the nest site, after which the male is the sole caregiver for an additional period at sea.
