White-tailed eaglePrior to experiments done with this bird of prey pheromones exist in larger numbers in nature. Amid an intense conservationists working populations in eastern Europe have returned. For the future it is planned to colonizate the other traditional breeding areas in Europe.
The mandarine smurf
Many monkeys of the species living in areas of Karnataka, Kerala and Tamil Nadu. Natural habitat of this species is composed of tropical forests of India, forests have largely been cleared to make way for plantations of tea and coffee. Currently the main factor underlying the extinction of species as in other mammalian species disappearance of their natural habitat. Poachers and they contribute to species extinction by capturing mostly the offspring of macaques in order to export them to collectors of exotic animals. The species is also hunted for their fur and meat. As one of the most endangered monkey species on Earth at present there are about 4000 copies to live in freedom.
The donkey penguin
This large bird was once one of the most common on the coast of South Africa. At present the only existing species of penguin in Africa. Because I live in the Northern region, these penguins are vulnerable to human activity took place there, due to reduced food resources seals have started to hunt to feed. The species is also threatened by oil spills and the sea and the fact that their eggs are taken to be consumed or destroyed.
The montain Gorilla
Mountain gorillas live in eastern Zaire, Uganda and Rwanda. Today has become an endangered species. Central causes disappearance of these gorillas are pitfalls, mainly intended for other animals, leading to massive deforestation of their natural habitat and the disappearance of many common diseases and man. The existence of the species depends on a host of massive forests, forests that unfortunately are cleared to make way for crops and pastures to be replaced. Because humans and gorillas are just 98% of genetically at risk of the same disease. Currently there are approximately 700 wild specimens of this species.
The only place in nature where this species lives is Western Australia, particularly in forested areas in this part of the world. At present the species is almost entirely disappeared, the only place where one can find a few copies is south-west Australia. With the arrival of human predators have been introduced animals like cats, foxes and dogs that have hunted and eaten numbatul. Their number is continuously decreasing because their habitat is transformed into mines and fields.
The Weasel with black paws
This mammal is one of the most endangered in North America isthe extinction in the wild frontier. The main cause of extinction of thisspecies is habitat occupation by human activity. Colonies of prairiedogs are being left in small and fragmented, separated byfarmlands and other areas of human activity. By the end of 2010biologists hope to reach a total of 1,500 copies in the wild and ineach population to be at least 30 breeding adults fit.
