Hunting for food may differ between dragon species e.g Tundra eats vegetation not meat. So we can use the FR slang from the site here as well for food

Foraging: Getting plants for herbivores and omnivores.

Insect Catching: Getting insects for insectivores and dragons who also eat insects as well.

Hunting: Getting fresh kill/prey for meat eaters or omnivores.

Fishing: Getting seafood for piscivores and dragons who also eat fish as well.
