Keen Sight and Smell. The peryton has advantage on Wisdom (Perception) checks that rely on sight or smell.

Lore

Although this monstrous carnivore feeds on any creature, it prefers humanoids, especially elves, half-elves, and humans. When it kills a humanoid, a peryton rips out its prey's heart and takes it back to its nest to be devoured.
