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 species of animal).〔(), "Amazon", 3/14/2011〕 Over 1,300 of these species are types of birds, which accounts for one-third of all bird species in the world. The diets of rainforest birds greatly differ between species, although, nuts, fruits and leaves are a common food for many birds in the Amazon. Birds migrate to the Amazon rainforest from the North or South. Amazon birds are threatened by deforestation since they primarily reside in the treetops.〔(), "Biodiversity in the Amazon", 2011〕 At its current rate of destruction from deforestation, the rainforest will be gone in forty years.〔(), "Rainforest Facts", 3/20/2010〕 Human encroachment also negatively affects the habitat of many Amazonian birds. The production of agriculture and road clearings limits the areas that birds are able to reside in the rainforest. Birds in the Amazon are distinguished by which layer of the rainforest they reside in. Each layer or community has unique plants, animals and ecosystems.〔(), "Amazon Rainforest", 2003〕 Birds interact with other animals in their community through the food chain, competition, mating, altruism and symbiosis.〔(), "Amazon Rainforest Ecosystem", 2010〕
==Habitat==
The Amazon rainforest has four layers, each of which has its own unique ecosystem. The top layer is the emergent (or dominants) where the tallest trees are found (up to 200 feet tall). Many birds, such as eagles and parrots, also reside in the emergent. The primary layer of the rainforest is the canopy where about 70 to 90 percent of all rainforest life resides. Plants in this layer have a large amount of fruit, seeds and flowers. Birds such as the toucan live in the canopy. The understory is the next layer of the rainforest where very little sunshine reaches; only about 2 to 15 percent of sunshine reaches the understory. The darkest layer is the forest floor where most of the larger animals live.〔(), "Amazon Rainforest", 2001〕
With multiple environments, the Amazon rainforest is able to provide a home to thousands of birds with different survival needs.〔 Amazonia is commonly dived into eight areas of endemism (districts): Napo, Imeri, Guiana, Inambari, Rondonia, Tapahos, Xingu and Belem. Although each area is similar in ecological characteristics, their biotas were assembled differently.〔(), "The Fate of the Amazonian Areas of Endemism", 6/5/2005〕
