White-billed Diver vs Black-browed Albatross

The White-billed Diver (Yellow-billed Loon) and Black-browed Albatross are easily distinguished by their habitat and bill color. The diver has a large, pale yellow bill and inhabits freshwater lakes in the Arctic, while the albatross has a black brow and a yellow-orange bill, frequenting open ocean environments.

Bill color is the most reliable mark: White-billed Diver has a pale yellow bill, while Black-browed Albatross has a yellow-orange bill with a black tip. Habitat is key: divers are on freshwater, albatrosses are oceanic. Plumage: look for the black brow on the albatross and the more uniform grey-white of the diver. Size: albatrosses are larger with longer wings.

The White-billed Diver is a large loon, but the Black-browed Albatross is even larger, with a wingspan that far exceeds the diver's.

The White-billed Diver has a predominantly white and grey plumage in non-breeding season, while the Black-browed Albatross is mostly white with a distinctive black brow and dark upper wings.

The White-billed Diver is territorial and often seen alone or in pairs on freshwater lakes, whereas the Black-browed Albatross is more social, often seen gliding over the ocean in flocks.

White-billed Divers are found on Arctic lakes and rivers, while Black-browed Albatrosses are oceanic, found in the Southern Hemisphere's open seas.

The White-billed Diver is known for its eerie wailing calls, especially during the breeding season. The Black-browed Albatross is generally silent at sea but may make croaking sounds at breeding colonies.
