Birds

Waterfowl are those birds ecologically dependent or semi-dependent on wetlands for foraging, housing or reproduction. Dependent birds spend little time in dry places, and spend most of their lives in wet areas. Semi-dependent birds are those that even manage to spend a long time in dry areas, but their beak, feet and legs morphological characteristics are the result of a long process of adaptation to humid areas. They are among the most threatened ecosystems in the world, as they suffer from the action of pesticides, chemicals and effluents from industries and human communities that are discarded in these places, being considered priority areas for the conservation of biodiversity.
