  1. They cannot feel pain
  2. In nature, looking weak is dangerous ✔
  3. They get sick less than other pets

Why: In the wild, a bird that looks weak can draw predators. Pet birds keep this habit, so a sick bird may look normal until it is quite ill.

Huh, didn't know that: Merck says to learn how your bird usually acts so you can spot changes early.
