Pintado Petrel

Identification

The pintado petrel is a striking and relatively small seabird, measuring 35–40 cm in length with a wingspan of 80–90 cm. Its most distinctive feature is its bold pied plumage: a black head and neck contrasts sharply with a white belly and breast, while the underwing is predominantly white with a black border. The back and upperwings display characteristic black and white speckles, as does the tail, which bears a band of black. Two subspecies are recognized—the northern D. c. capense has a white back with black spots, while the southern D. c. australe is smaller with a solid blackish-brown back. As a member of the order Procellariiformes, pintado petrels share distinctive anatomical features including naricorns (nasal passages attached to the upper bill) and a unique ability to produce and spray stomach oil as both a defense mechanism and energy source.

Range & Habitat

This abundant seabird is endemic to the Southern Ocean, with a global population estimated at around 2 million individuals. Pintado petrels breed on circumpolar subantarctic and Antarctic islands, including the Antarctic Peninsula, South Georgia, the Kerguelen Islands, the Balleny Islands, and islands in the Scotia Sea, extending as far north as the Auckland Islands, Chatham Islands, and Campbell Island. During breeding season they feed at sea around Antarctica, but in winter they range considerably further north, reaching as far as Angola and even the Galapagos Islands near the Equator in cold currents. They nest colonially on cliffs or level ground within a kilometer of the ocean, constructing nests from pebbles and shells and sheltering them under overhanging rocks or in crevices.

Behaviour & Diet

Pintado petrels are highly gregarious birds, famous among mariners for following ships and scavenging edible waste and carcasses thrown overboard. Their diet comprises approximately 80% crustaceans, with krill being their preferred food, which they obtain both by surface seizing and by diving and filtering underwater. They also feed on fish and squid. These petrels are notably aggressive while feeding and will spit their potent stomach oil at competitors, even members of their own species, in defense of food resources.

Breeding occurs from November, when pairs lay a single clear white egg incubated for 45 days by both sexes. Chicks are brooded for ten days after hatching, then fledge approximately 45 days later around March. Like other fulmars, adults vigorously defend their nests by spitting stomach oil, though skuas remain a significant predatory threat to eggs and chicks.

Best Time & Places to See It

Pintado petrels are most reliably observed during breeding season (November to March) on subantarctic and Antarctic islands, particularly at major breeding colonies on the Antarctic Peninsula, South Georgia, and the Kerguelen Islands. Ship-based expeditions to these regions offer the best opportunities for sightings. Outside breeding season, they are widespread across Southern Ocean waters and can be encountered during seabird-watching cruises to high southern latitudes, particularly in cold-current systems.

Photography Tips

The pintado petrel's striking black-and-white plumage provides excellent contrast for photography. From ships, photograph birds in flight against open ocean to capture their distinctive pied pattern, particularly the white underwings with black borders and speckled back. When at breeding colonies, patient observers can document nesting behavior and the birds' characteristic defensive postures. Early morning and late afternoon light will best illuminate the sharp contrast between their dark and light plumage, making these abundant seabirds highly photogenic subjects for wildlife photographers working in polar regions.
