DEFORESTATION AND
THE BIRDS OF THE
ATLANTIC RAINFOREST
The Atlantic Rainforest is a biome with a high number of species that live in very small areas, called endemism. When these forests are cleared, even sometimes small forest areas, these species lose their chance to survive and become extinct.

The Atlantic Rainforest is home to the largest number of endemic species of the Brazilian biomes. There are 231 bird species endemic to the Atlantic Rainforest.
Dozens of them occur in very restricted areas. This makes them especially vulnerable because a stochastic event such as a fire, a disease, a flood or storm, or the invasion of an exotic species can suddenly put an end to a species.
An example is the Alagoas antwren (Myrmotherula snowi). There are 35 known individuals of this species in all the world, all restricted to a small reserve.
On top of that are added other threats such as trafficking and hunting of animals. Consequently, there are 120 species and subspecies of Atlantic Rainforest birds threatened with extinction. And this number continues to grow.
41% of the bird species threatened with extinction in Brazil are native to the Atlantic Rainforest.
