Puffins, the Parrot of the Sea

It’s August on the coast of Iceland, and the air is full of the deep garbled growls of tons of of puffins. The social birds have come to shore for the brief breeding season, and the rocky banks are dotted with their squat, football-shaped our bodies. From the ocean bursts a shiny five-year-old male carrying a dozen small herring in his beak. Flapping his wings mightily, he rises from the waves to the rocky cliffs the place a hungry chick waits silently in a burrow hidden within the rocks. The puffin circles the sky above the burrow a number of occasions, searching for herring gulls, which typically wait ashore to steal a puffin’s catch. However the coast is obvious and the puffin swoops down, getting into the darkish burrow with a flurry. Immediately the chick springs to life, demanding its meal with tiny squeals. Downy grey and plump, with a sliver of a beak, the chick hardly resembles its putting black and white father. Giant and colourful beaks, which can fall off after the season is over, have given these arctic birds their nicknames-the sea parrot.

It was as soon as questioned whether or not the pelagic puffin was a cross between a chook and a fish. Awkward and clumsy-looking on land, it definitely seems more proficient within the sea, the place its brief wings successfully propel it by means of the water after small herring and sand eels. Its webbed ft perform as a rudder, permitting the chook to maneuver sharp turns. Puffins can fly, and can truly beat their wings 100-400 beats per minute to turn into airborne. However due to the trouble required to take flight, puffins will nest on cliffs the place they extra simply swoop down into the ocean. Puffins fly low to the water, and may attain speeds as much as 55 miles per hour.

A puffin’s eating regimen comes from the icy depths of the ocean, and a mean dive can final twenty or thirty seconds, or extra. With their specialised beaks, puffins are capable of maintain a number of fish at a time. Their raspy tongues maintain fish towards spines on their palate whereas they open their beak for extra. A mean catch can be 10-12 fish, however one puffin reportedly introduced 62 fish in its beak at one time! Waterproof feathers present safety from the chilliness of even the coldest waters within the arctic area. Even its coloration lends to its survival within the sea. The puffin’s darkish coloring on its again make it troublesome for predators to differentiate it from the darkish waves because it floats on the ocean, whereas from under its white underside masks it from ocean enemies. This misleading coloring is known as counter shading.

Around the globe it’s estimated that 12-15 million puffins exist as three species: The horned puffin, named for its sexy projections above its eyes; the tufted puffin, which has conspicuous straw-colored feathers extending from its crown throughout mating season; and the Atlantic puffin, the one puffin to stay on the Atlantic Ocean, which has a steel-blue triangle on the base of its beak. Within the 1800s over-hunting obliterated a local inhabitants in Maine, which has since been restored. They don’t seem to be presently threatened. Puffin colonies are discovered breeding off the coasts of Alaska, Canada, North America, and North Asia; though Iceland is the breeding quarters of the most important inhabitants of puffins. Coastlines are full of hundreds of breeding pairs through the summer time months. Puffins are monogamous, and whereas companions might half for the winter, which they spend out on the open sea, they often return to the identical companion, and even the identical nest.

The rigorous mating ritual begins whereas the pair continues to be at sea. Breeding pairs interact in billing one another, skypointing (flying straight up), and strutting. By the point birds attain the shore, partnerships are well-established. The male digs the burrow utilizing his beak to chop into the soil and his ft to shovel the rocks and different unfastened materials away. Ideally, the burrow can be 2-Three ft lengthy and shielded from predators by rocks. Right here the feminine lays one egg per yr. Collectively, the pair incubates the egg, every taking a flip holding it underneath one wing and urgent it towards its physique. Cooperating on this means, each birds are capable of depart the nest to feed.

When the egg hatches 40-53 days later, the mother and father proceed to share duty for the chick. Feeding happens 4 to 5 occasions a day, and after the primary day of life the chick might be left alone within the burrow to attend for its subsequent meal. The chick stays within the burrow about 40-55 days, whereupon it waits till night earlier than independently approaching the opening of the burrow for the primary time. The fledgling units out to sea by itself, the place it should reside for the subsequent two years. Puffins attain sexual maturity at Three years previous, however won’t usually return to their nesting grounds to mate till Four-5 years previous. Puffins reside lengthy lives of 20 years or extra.

Traditionally people have used the puffin for meat and clothes (its pores and skin is waterproof and heat when worn with the feathers turned inside), however searching is usually discouraged in the present day. In some nations it’s forbidden by regulation. In the meantime, man has come to worth puffins as indicators of ocean well being. By observing the situation of the puffin inhabitants, scientists decide whether or not over-fishing or dangerous air pollution is happening. Oil spills threaten puffins by de-waterproofing their feathers, making them weak to chilly temperatures. One other unfavorable influence on puffin colonies has been the unintentional introduction of rats and foxes to summer time nesting areas.
