Adaptations in mammals. At some early stage during the evolution of viviparous mammals, eggs came to be retained in the oviducts of the mother. The embryo then was provided with nourishment from fluids in the oviduct; the yolk, which became redundant, gradually ceased to be provided, and the eggs became oligolecithal.
What do Anseriformes eat?
Most anseriformes feed on plants or their parts, such as leaves or seeds. Some of them can hunt for insects, plankton, or mollusks. Not only do waterfowl birds have many predators, both on land and in water, they also are threatened by human hunters, for most of these species are popular as game.
