Southern Giant-Petrel (macronectes giganteus)
This particular bird has an incredibly aerodynamic shape . The distance between the ends of both extended wings is up to 2m. An adult male can weigh up to 5 kg.The characteristic of the Family is that they are tubinares, that means that their tip adopt the shape of a unique nasal tube , but divided inside in two by a central partition.
They have just one egg and both parents alternate themselves during the incubation and the feeding process. The giant Petrel has a great sense of smell, being by this way able to find food on the coasts, they not always kills penguins or elephant seals to eat.In the sea they feed themselves with waste that hundreds of boats throw away, like tons of fishes wich are to good for humans. By these way we explain that the waste of human depredation is helping the Great Petrel to increase its survival capacity and doing the reproduction cycle more productive. Consequently these birds population are in bigger proportion than previous years. The giant petrel is under monitoring, wich has demonstrated that they can flight incredible distances. A bird fastened with rings in New Zealand has been seen one week later in patagonik coasts, wich implies that they flew more than 5000 km in 7 days!!!
