About These Birds

Grey-backed Storm-petrel

Grey-backed Storm-petrel, 16–19 cm, breeds on sub-Antarctic islands across the Southern Ocean from Tristan da Cunha to the Antipodes. Pale grey back and rump distinguishes it from most other storm-petrels. Planktivore; flutters low over the sea surface picking up zooplankton.

White-vented Storm-petrel

White-vented Storm-petrel, 15–17 cm, is a small, poorly known storm-petrel of the eastern South Pacific. Dark above with white rump and white vent. Pelagic off the coasts of Peru, Chile, and Ecuador; breeding grounds discovered only recently on tiny Patagonian islands. Planktivore.
