Townsend's shearwater Townsend's shearwater The Townsend's shearwater, "Puffinus auricularis", is a rare seabird of the tropics from the family Procellariidae. Its relationships are unresolved.

Saba (IBA AN006 "Saba Coastline") by BirdLife International. Saba is home to about sixty species of birds, many of which are sea birds that use the holes and crevices of the steep cliffs and two small islands for breeding and feed in the waters around the island. Saba’s shoreline is home to the Caribbean’s largest breeding colony of Red-billed tropicbird ("Phaethon aethereus"). The Audubon's Shearwater ("Puffinus lherminieri") is another common bird, and is the national bird of Saba as well as being featured on their coat of arms. Being an island, Saba is home to a number of endemic species including
