This migratory bird was chosen to be the bird of the year 2011 by PSSB, a distinction that is an alert to the drastic decrease of this specimen on the planet.
The shearwater can be recognized by its brown back, white belly and yellow beak, but what truly distinguishes it from other birds is the call that seems the raucous laughter of a hyena that swallowed a mixing console is the best way I have to describe the sound they reproduced. It sounds fun but it is not. Just listening to it and the perception is different, since in no way resembles the triple of a bird. If you doubt my word, just listen to his "calling" and assess for yourselves through the link of the Portuguese Society for the Study of Birds, which is at the end of this text. Continuing.
This bird travels long distances, to the point of spending most of his life flying over the oceans of temperate and cold water. The only period of your existence when in fact they spend more time on land is when they decide to nest. Every year the shearwaters choose the same partner and lay eggs on the same island or rock where they reproduced the first time, which creates a large concentration of these migratory birds. Now, imagine hundreds of them "screaming" at the same time.
The Portuguese territory is one of his favorite places for this purpose, inter alia, on the Deserted Islands located in the Madeira Archipelago, Berlengas and in large numbers in the Azores. These migratory birds arrive to the places of posture during the month of March where they build their nests in a kind of den that is visited by parents only during the night. Then, the offspring are born in May and leave the nest in October, its animal instinct dictates this march for the high seas.
The distinction of the Portuguese Society for the Study of Birds came in as an alert to the dramatic decrease of the specimen, due to human interference and increasing pollution of the oceans, as these birds feed exclusively on fish and cephalopods.
