Population 150,000

A striking and energetic seabird that spends most of its life roaming the open oceans of the Southern Hemisphere. It gets its name from the pale collar that wraps around its neck, which contrasts sharply with its dark cap, back, and wings. This bold pattern makes it easy to recognize when it sweeps low over the waves. Medium-sized but powerful, the white-necked petrel is built for speed and endurance. Its long, narrow wings allow it to glide smoothly and then suddenly burst into rapid flight, a style perfectly suited for searching wide stretches of ocean.

Unlike smaller, more delicate-looking petrels, this species is robust and assertive. It breeds mainly on remote islands, often choosing steep, forested slopes where it digs burrows for nesting. These nesting sites provide protection from weather and predators but require strength and determination to access. White-necked petrels are also known for their loyalty to breeding areas, returning to the same islands year after year. During the breeding season, pairs form strong bonds and work together to raise a single chick, sharing duties such as guarding the nest and searching for food.

At sea, the white-necked petrel is an active and skilled forager. It feeds mainly on squid, fish, and other small sea creatures, often catching prey near the ocean’s surface. It uses a combination of sharp eyesight and a strong sense of smell to locate food across vast, seemingly empty waters. The bird’s flight style is fast and purposeful, with quick changes in direction as it follows wind patterns and ocean currents. It is not unusual for a white-necked petrel to travel enormous distances in search of food, sometimes crossing entire ocean regions during a single foraging journey.
