Tufted Puffin
 (Fratercula cirrhata)
A large (780 g) species of Alcidae, this is perhaps the most ornate and beautiful member of the family. Unlike Cassin's and Rhinoceros auklets, Tufted Puffins have a diurnal pattern of activity on the colony, but like their smaller relatives, they too nest in earthen burrows in which the female lays a single white egg. Both parents incubate in turn for about 45 days, and each delivers a billfull of food to the chick once to several times per day.
Interestingly, while the adults themselves feed mainly on large zooplankton, they feed small forage fish such as sandlance to the chick. The chick fledges after 40 days or more in the burrow. Triangle Island supports about 30,000 breeding pairs of Tufted Puffins.
