Birds of the Amazon roads and logging deters birds and other animals from living in those sections of the forest. It can be observed that there is a lot less bird movement near areas with roads and lodging than those without. Understory species are especially vulnerable to effects of road clearing. Even roads that are narrow with less traffic can have a significant impact on the movements of insectivorous birds in the Amazon. Birds of the Amazon An immense number of bird species live in the Amazon rainforest and river basin (an area which is nominally home to one out of every ten known
