The Broad-billed Prion is a seabird with a broad bill. Comb-like edges in the bill help it filter small organisms from the sea.
It has a high forehead and broad bill. The upperparts are grey to dark, the underparts are white, and a dark M-shaped mark crosses the back.
At sea it filters small marine organisms with its broad bill. On breeding islands it nests in burrows or crevices.
