Staravia is a grayish-brown, avian Pokémon with black and white markings. Its head and upper body are primarily black with an "M"-shaped pattern over its white chest. On its forehead is a grayish-brown spot, which is smaller on the female. On its face is a white, mask-like marking with a pattern of spikes along the lower edge. It has small, black eyes with white pupils and a long, orange beak with a black tip. On the back of its head is a long tuft of feathers, which curves forward. The lower halves of its wings are black, and it has black tail feathers with a single white feather in the center. Its orange, anisodactyl feet have black talons.
Staravia lives near forests and fields, where it hunts for Bug Pokémon. Aware of its own weakness, it forms flocks of its own kind and cries noisily if left on its own. However, these flocks can be extremely territorial. When two different groups meet, they will have fierce territorial disputes.
In the Hoopa's Surprise Ring Adventures short Flying in the Air, Hoopa summoned multiple Staravia to create wind for Ash and Pikachu, but their combined Gust was too much for them and sent them blasting off.
