Some of them move by flying. Examples of Aves are Picoides pubescens , which is a woodpecker, and Anas platyrhynchos , which is a duck. There are many examples of adaptation in the deciduous forest. Some birds are able to survive the winter by flying south where it is warmer and easier to get food. That way they have a greater chance of existing longer.
Trees shed leaves every fall because the chlorophyll in the leaves breaks down.
When leaves, fall it puts the tree to sleep for the winter, which helps it survive because, during the winter, there are not enough nutrients for it to feed on. When a dandelion pollinates, it spreads its seeds very far for a greater chance at reproducing. A big environmental issue in the deciduous forest is deforestation. Trees are cut down for paper, which destroys the habitat for many animals, which puts them at risk of extinction. Some endangered species in the deciduous forest disappeared for a while but are finally coming back because of conservation measures being taken to save the forest.
