Essential Black-browed Albatross Information
Habitat and Identification
The Black-browed Albatross is widely found in the sub-Antarctic region and is frequently seen at sea, especially during crossings to and from Antarctica. They have a wingspan of up to 2.4 meters (7 feet 10 inches) and weigh between 3.2 and 4.5 kg (7 to 10 pounds). This species is known for its distinctive dark brow above the eyes, giving it a unique appearance. Despite their presence in Antarctic waters, they breed primarily on the outer islands of the Falklands, where about a third of the world’s population resides.
Lifespan and Population
These birds are long-lived, with some individuals reaching up to 70 years of age. The total global population is estimated at around 1.2 million birds, with a significant portion breeding in the South Atlantic on the Falkland Islands.
Feeding and Behavior
The Black-browed Albatross primarily feeds on fish, squid, and crustaceans but is known to be an opportunistic feeder, occasionally stealing from other species. These albatrosses produce a waxy stomach oil, which serves as both a high-energy food source for their chicks and a defense mechanism against predators, as they can expel the sticky oil from their beaks.
Flight and Movement
On land, they may appear somewhat clumsy, but in the air, they are graceful gliders. They skillfully skim over the ocean waves with minimal wing flapping, showcasing their remarkable flying abilities. These birds are often seen during ocean crossings, making them a highlight for travelers on Antarctic cruises. Guides are usually on hand to help distinguish the Black-browed Albatross from other similar species.
