Rhinoceros Auklet (Cerorhinca monocerata)
This unusual member of the Alcidae is actually a puffin, not an auklet. It is medium sized (525 g), nocturnal, nests in burrows and feeds mainly on fish. It too lays a single white egg, which is incubated in turn by both parents for about 45 days.
Like Cassin's Auklet chicks, Rhinoceros Auklet chicks are usually fed once each night by each parent - one billfull of small fish, which might include Pacific sandlance, Pacific saury, and even some young Pacific salmon. They fledge at about 55 days of age. Triangle supports about 40,000 breeding pairs of Rhinoceros Auklets.
