Crows are ordinary birds found all over the map, and they never attack you. They matter for two reasons: their meat sells at camp kitchens, and a flock overhead often means Freakers or a Horde are close.
A crowd of crows often gathers near danger, and that danger is often a Horde. When you see them, slow down and check with Survival Vision.
Crows are easy meat when you are short on credits. A quiet weapon keeps the shot from drawing Freakers nearby.
Bring the meat to any camp kitchen. Early on it also covers Boozer's meat errand, which accepts crow along with deer and wolf.

Bears are big, tough animals that charge, bite and claw for heavy damage. You meet the first one while escorting Lisa in Lots of Sick People. After that they can turn up anywhere, so carry a strong rifle or a throwable.
Deer
Deer are harmless game animals that run when they notice you. Hunt them for meat to sell at camp kitchens, and Copeland walks you through tracking and gutting one early in the game.
