About These Birds
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
Rhinoceros Auklet
Alca-de-chifre (Cerorhinca monocerata), 35–40 cm. Plumagem escura acima e branca abaixo, com filamentos faciais brancos no adulto reprodutor e protuberância basal no bico. Habita costas e ilhas do Pacífico Norte. Nidifica em tocas. Alimenta-se de peixes e crustáceos capturados por mergulho.
