A tame animal or bird is one that is not afraid of humans.

If you say that something or someone is tame, you are criticizing them for being weak and uninteresting, rather than forceful or shocking.

If someone tames a wild animal or bird, they train it not to be afraid of humans and to do what they say.

If you tame someone or something that is dangerous, uncontrolled, or likely to cause trouble, you bring them under control.
