Which seabird makes a transoceanic migration from the Falkland Islands to the North Atlantic?

The sooty shearwater makes a transoceanic migration from the Falkland Islands to the North Atlantic.

Sooty shearwaters breed in colonies on islands and coastal headlands around the Southern Hemisphere, including New Zealand, Australia, Chile, and the Falkland Islands. After breeding, many travel north through the Atlantic or Pacific to exploit productive northern waters during the opposite hemisphere’s summer.

The species is among the world’s great migratory seabirds. Researchers tracking individuals have documented annual journeys of roughly 64,000 kilometres in some populations, although routes differ by colony. The birds spend much of their lives at sea and are adapted for efficient gliding over waves.

Sooty shearwaters are often confused with the smaller Manx shearwater, especially where their ranges overlap at sea. Their dark brown plumage, pale throat, and strongly hooked bill help distinguish them. They return to land mainly to breed, usually nesting in burrows or natural cavities on predator-free islands.
