I've read about wolves that they eat only the meat they are taught to eat (and different pack of wolves in different places hunt different animals.) So a wolf may literally starve to death while sitting near a corpse of some animal if it doesn't know it can eat it. May happen to pups if their pack dies or to wolves who were brought up in captivity.

The source is in Russian from a zoologist who studied wolves: https://sovet.blocknote.info/articles/443/serdtse-volka-semy...

Some behaviors are instinctive, some are taught, some are the result of emotional conditioning (hence people taming and domesticating animals).
