Ragers are infected black bears and the toughest animals in the game, with well over twice a normal bear's health. Treat one like a boss fight: keep your distance, set it on fire and pour in shotgun or heavy rifle rounds.
A Rager charges hard and keeps coming through damage that would drop anything else. Its swipes and bites take big chunks of health. Its hearing picks up careless movement, so expect it to find you if you get loud.
Open with a Molotov or Napalm Molotov to stun and slow it. Use that window to back off and unload a shotgun or strong rifle. Keep a second firebomb ready for when it recovers. Grenades and pipe bombs help close the gap on its health bar.
The first Rager attacks a Militia patrol in Mayday! Mayday!, as you come over the ridge into the Diamond Lake valley. Another waits at the end of Nose Down, They Feed Ya, a hostage job for Copeland.
With Executioner, breaking out of a Rager's grab lets you finish it on the spot. That is one of the safer routes to This is a Knife.

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.
Crier
Criers are infected ravens that nest in trees and on power-line transformers in the south. They dive in erratic lines and keep coming from their nests, so destroy the nests before you waste ammo on the birds.
Crows
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.
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.
