About These Birds

Ainley's Storm-petrel

Ainley's Storm-petrel, 19–21 cm, is a recently described species breeding on the Channel Islands off California, present in winter — unusual among storm-petrels which typically breed in summer. Dark overall, white rump with central grey stripe. Vulnerable; small population and restricted range.

Markham's Storm-petrel

Markham's Storm-petrel, 22–23 cm, is a large all-dark storm-petrel breeding in the Atacama Desert of Chile and Peru — one of the few seabirds to nest in desert habitat far from the coast. Poorly known. Near Threatened. Pelagic over the Humboldt Current and cold eastern South Pacific waters.
