Description

Tufted Puffins are around 35 cm (15 in) in length with a similar wingspan and weigh about three quarters of a kilogram (1.6 lbs). 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.

They are mostly black with a white facial patch, and, typical of other puffin species, feature a very thick bill which is mostly red with some yellow and occasionally green markings. Their most distinctive feature and namesake are the yellow tufts that appear annually on birds of both sexes as the summer reproductive season approaches. Their feet become bright red and their face also becomes bright white in the summer. During the feeding season, the tufts moult off and the plumage, beak and legs lose much of their lustre.
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
Myoglobin
Myoglobin is an iron- and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals. It is related to hemoglobin, which is the iron- and oxygen-binding protein in blood, specifically in the red blood cells. The only time myoglobin is found in the...

 strenuous wing-beat cadence, which they can nonetheless maintain for long periods of time.

Juvenile puffins resemble winter adults, but with a grey-brown breast, white belly, and a shallow, brown bill.

They have been known to nest in small numbers as far south as the northern Channel Islands, off southern California. However, the last confirmed sighting at the Channel Islands occurred in 1997.

Tufted Puffins typically select island

 or other invertebrates. Feeding areas can be located far offshore from the nesting areas. Puffins can store large quantities of small fish in their bills and carry them to their chicks.

Predators and threats

Tufted Puffins are preyed upon by various avian raptors such as Snowy Owls, Bald Eagles and Peregrine Falcons, and mammals like the Arctic Foxes. Foxes seem to prefer the puffin over other birds, making the bird a main target. Choosing inaccessible cliffs and entirely mammal-free islands protects them from terrestrial predators while laying eggs in burrows is effective in protecting them from egg-scavengers like gull

Conservation Status in Puget Sound

Many rules and regulations have been set out to try to conserve fishes and shorebirds in Puget Sound. The Department of Natural Resources (DNR) of Washington State has created aquatic reserves surrounding Smith and Minor Islands. Over 36000 acres (145.7 km²) of tidelands and seafloor habitat were included in the proposed aquatic reserve. Not only do these islands provide the necessary habitat for many seabirds such as tufted puffins and marine mammals, but this area also contains the largest kelp beds in all of Puget Sound. In addition, Protection Island reserve has also been off limits to the public to aid marine birds in breeding. Protection Island contains one of the last two nesting colonies of puffins in Puget Sound, and about 70% of the tufted puffin population nests on this island.
