Tufted Puffin

Identification

Tufted puffins are around 35 cm (14 in) in length with a similar wingspan and weigh about three-quarters of a kilogram (1.6  lbs), making them the largest of all the puffins. Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females.<p>They are primarily black with a white facial patch, and, typical of other puffin species, feature a very thick bill, primarily red with some yellow and occasionally green markings. Their most distinctive feature and namesake are the yellow tufts (Latin: cirri) that appear annually on birds of both sexes as the summer reproductive season approaches. Their feet become bright red and their face is also bright white in the summer. During the feeding season, the tufts molt off and the plumage, beak, and legs lose much of their luster.<p>As among other alcids, the wings are relatively short, adapted for diving, underwater swimming, and capturing prey rather than gliding, of which they are incapable. As a consequence, they have thick, dark myoglobin-rich breast muscles adapted for a fast and aerobically strenuous wing-beat cadence, which they can nonetheless maintain for long periods of time.<p>Juvenile tufted puffins resemble winter adults, but with a grey-brown breast shading to white on the belly, and a shallow, yellowish-brown bill. Overall, they resemble a horn-less and unmarked rhinoceros auklet (Cerorhinca monocerata).

Taxonomy

The tufted puffin was first described in 1769 by German zoologist Peter Simon Pallas. The scientific name Fratercula comes from the Medieval Latin fratercula, friar, a reference to the black and white plumage which resembles monastic robes. The specific name cirrhata is Latin for "curly-headed", from cirrus, a curl of hair. The vernacular name puffin – puffed in the sense of swollen – was originally applied to the fatty, salted meat of young birds of the unrelated species, the Manx shearwater (Puffinus puffinus), formerly known as the "Manks puffin". It is an Anglo-Norman word (Middle English pophyn or poffin) used for the cured carcasses. The Atlantic puffin acquired the name at a much later stage, possibly because of its similar nesting habits, and it was formally applied to that species by Pennant in 1768. It was later extended to include the similar and related Pacific puffins.<p>Since it may be more closely related to the rhinoceros auklet than the other puffins, it is sometimes placed in the monotypic genus Lunda.<p>The juveniles, due to their similarity to C. monocerata, were initially mistaken for a distinct species of a monotypic genus, and named Sagmatorrhina lathami ("Latham's saddle-billed auk", from sagmata "saddle" and rhina "nose").

Range and habitat

Tufted puffins form dense breeding colonies during the summer reproductive season from Washington state and British Columbia, throughout southeastern Alaska and the Aleutian Islands, Kamchatka, the Kuril Islands and throughout the Sea of Okhotsk. While they share some habitat with horned puffins (F. corniculata), the range of the tufted puffin is generally more eastern. They have been known to nest in small numbers as far south as the northern Channel Islands, off the coast of southern California. However, the last confirmed sighting at the Channel Islands occurred in 1997.<p>Tufted puffins typically select islands or cliffs that are relatively inaccessible to predators, close to productive waters, and high enough that they can take to the air successfully. Ideal habitat is steep but with a relatively soft soil substrate and grass for the creation of burrows.<p>During the winter feeding season, they spend their time almost exclusively at sea, extending their range throughout the North Pacific and south to Japan and California.
