The white-chinned petrel also known as the Cape hen and shoemaker, is a large shearwater in the family Procellariidae. It ranges around the Southern Ocean as far north as southern Australia, Peru and Namibia, and breeds colonially on scattered islands. The white-chinned petrel was formerly considered to be conspecific with the spectacled petrel.
Region
Southern Ocean
Typical Environment
Pelagic over cold-temperate and subantarctic waters encircling the Southern Ocean, ranging north to the waters off southern South America, South Africa, Australia, and New Zealand. Breeds colonially on subantarctic islands in the South Atlantic, Indian, and southwestern Pacific sectors, nesting in burrows on slopes with tussock or peat soils. Forages widely over continental shelf edges, oceanic fronts, and productive upwelling zones. Frequently attends fishing vessels for discards and offal. Nonbreeding birds disperse across vast oceanic areas.

Also called the Cape hen or shoemaker, the white-chinned petrel is a large, dark procellariid that ranges widely across the Southern Ocean. Its small white patch on the chin can be faint or absent in some individuals. The species is highly vulnerable to bycatch in longline and trawl fisheries and was formerly lumped with the spectacled petrel. Like many petrels, it produces energy-rich stomach oil used to feed chicks and for self-defense.

Social Behavior
Breeds in large colonies, nesting in burrows or crevices and laying a single egg. Mostly nocturnal at colonies, likely to reduce predation. Adults show high site fidelity and long-term pair bonds. Outside breeding, gathers in loose flocks over rich feeding areas and behind fishing vessels.
Migratory Pattern
Seasonal migrant
Song Description
At colonies, emits moans, chuckles, and rattling notes, with gruff, rhythmical calls that inspired the name 'shoemaker.' At sea it is generally quiet, vocalizing mostly during nocturnal colony activity.
