AVITOPIA - Storm-petrels

The family of Storm-petrels is widespread on all oceans of the earth and occurs partly in large numbers. With a body length of 14 cm to 25 cm, they are the smallest seabirds with webbed feet. Your weak legs are hardly able to carry their body weight without the support of the wings. They breed in colonies in caves or crevices, which they usually only attend at night. Although they usually breed on mammal-free islands, the greatest danger comes from introduced mammals. The Guadalupe storm-petrel was driven to extinction by feral cats.
