On one of the worlds of Brandon Sanderson’s Cosmere, magic is only found in animals, but fortunately these animals are generally restricted to a single archipelago. Said archipelago is basically a hellscape of horrifying predators that can hunt you down by detecting the presence of thoughts, have lethal poisons, and so forth - and it’s made worse by the fact that the few humans who do live there have a bizarre culture of trying to murder each other with traps. Said humans have learned to tame the less-violent birds to work symbiotically with them; the main character has one that makes thoughts undetectable within a given radius, and another that can show whomever it’s in physical contact with visions of their death, by way of warning (so if he’s likely to trigger a pit trap, he’ll see a superimposed image of the pit broken through and himself impaled at the bottom). These symbiotic birds appear to be the only way native humans can use magic.
