Flightless bird more species of flightless birds (including the kiwi, several species of penguins, the takahe, the weka, the moa, and several other extinct species) than any other such location. One reason is that until the arrival of humans roughly a thousand years ago, there were no large land predators in New Zealand; the main predators of flightless birds were larger birds. Ratites belong to the superorder Palaeognathae birds, which include the volant tinamou, and are believed to have evolved flightlessness independently multiple times within their own group. Some birds evolved flightlessness in response to the absence of predators, for example on
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
