Rhinoceros Auklet

Rhinoceros Auklet: Medium-sized seabird with black upperparts, dark gray underparts, and white belly. Eyes have long white plumes above and below. Bill is yellow with pale horn. Legs and feet are gray. Swims and dives for crustaceans and small fish. Fast direct flight with rapid wing beats.

● Song: Generally silent

● Foraging & Feeding: Rhinoceros Auklet: Feeds mainly on small fish, but sometimes takes crustaceans and squid; forages by diving from the surface and pursuing prey under water.

● Breeding & nesting: Rhinoceros Auklet: One white egg, often spotted, is laid in a burrow; nests in colonies, sometimes in large numbers. Incubation ranges from 39 to 52 days and is carried out by both parents.

● Similar species: Rhinoceros Auklet: In basic plumage, the smaller Cassin's Auklet, the whiter-bellied Parakeet Auklet, and larger-billed Tufted Puffin are all similar because they share the darker plumage.

Swift direct flight with rapid wing beats.
