New animals for biomes to replace the cows, sheep, chickens, and pigs.

I would like to see the Cows, pigs, sheep, and chicken removed from biomes, and only spawning in, or near villages as domestic animals, and be replaced with-

Deer, squirrels, songbirds, and raccoons.  These would be for all the forest biomes, plains, mountains, rivers, lakes, snow (but not ice).  They will NOT spawn in savannahs, swamps, deserts, mesa, jungle, or ice biomes, because I have new ideas for those :) 

Deer are obvious, and can be a potential food source. Shy of players. 

Squirrels are mischievous, and like nuts.  If you feed them, they will hold them in their cheeks.  They can also steal your food.  Chattering sounds.

Songbirds are a variety of different types, and eat berries, and seeds.  Make pretty songs for ambiance.

Raccoons are curious, and mischievous.  Can follow you around.

All are hunted by predators like wolves, and polar bears.
