... 2 ) in emperor penguins ( Aptenodytes forsteri ) equipped with backpack P O 2 recorders. Cervical air sac P O 2 values at rest were lower than in other birds, while the cervical air sac to posterior thoracic air sac P O 2 difference was larger. Pre-dive cervical air sac P O 2 values were often...

... of this behaviour in emperor penguins ( Aptenodytes forsteri ), whose failed breeders often kidnap chicks. We experimentally tested the hypothesis that kidnapping behaviour was the result of high residual levels of prolactin (PRL), a hormone involved in parental behaviour. Penguins with artificially decreased PRL...
