Northern Gannet,Ganso Patola

Description:

Young birds are dark brown in their first year, and gradually acquire more white in subsequent seasons until they reach maturity after five years. Adults are 81–110 cm (32–43 in) long, weigh 2.2–3.6 kg (4.9–7.9 lb) and have a 165–180 cm (65–71 in) wingspan. Before fledging, the immature birds (at about 10 weeks of age) can weigh more than 4 kg (8.8 lb). Their plumage is white with black wing tips. The bill is light bluish. The eye is light blue, and it is surrounded by bare, black skin. During breeding, the head and neck are brushed in a delicate yellow

Habitat:

Their breeding range is the North Atlantic. They normally nest in large colonies, on cliffs overlooking the ocean or on small rocky islands. The largest colony of this bird, with over 60,000 couples, is found on Bonaventure Island, Quebec, but 68% of the world population breeds around the coasts of Great Britain and Ireland, with the largest colonies on the Bass Rock (whence the species' Latin name) and Boreray, St Kilda. In the United Kingdom, gannets are a protected species. However, a legal exception is made for the inhabitants of the district of Ness (also known as Nìs) of the Isle of Lewis who are allowed to kill up to 2000 gannets (locally known as guga) annually to serve as a traditional local delicacy—the taste is described as fishy. Many of these gannets are taken from Sula Sgeir, which is itself named after them http://www.google.pt/url?sa=t&rct=j&...
