Thalassarche melanophris, commonly known as the Black-browed Albatross, is a large seabird found in the Southern Hemisphere. These birds are characterized by their impressive wingspans and distinctive markings, making them a captivating sight for seafarers and bird enthusiasts alike.
Description & Characteristics
The Thalassarche melanophris is a robust albatross with a wingspan that can reach up to 2.1 meters (6.9 feet). Their plumage is primarily white, except for a distinctive dark gray to black band that extends from the eye to the base of the bill, giving rise to their common name. This band is particularly prominent in adults, helping to distinguish them from other albatross species. The beak of the Thalassarche melanophris is long and hooked, featuring a distinctive yellow tip. Additionally, they have a distinctive dark gray coloration on their upperparts, while their underparts are primarily white.
Habitat and Occurrence
The Thalassarche melanophris is a highly pelagic species, meaning they spend most of their lives at sea, far from land. They primarily inhabit the Southern Ocean, ranging from the South Atlantic to the Indian Ocean and the Pacific Ocean. This species can be found in a variety of marine zones, including the neritic zone, the oceanic zone, and even the abyssal zone. The Thalassarche melanophris is a particularly common sight in the Southern Ocean’s Subantarctic waters, where they breed on remote islands. These birds can be observed soaring effortlessly over the vast expanse of the ocean, gliding on wind currents.
Taxonomy
The Thalassarche melanophris belongs to the Class: Aves, Order: Procellariiformes, and Family: Diomedeidae. This classification places it within the group of birds known as seabirds, specifically within the order of tubenoses. The Diomedeidae family encompasses a diverse group of birds, all characterized by their long wings, strong flight capabilities, and their ability to utilize wind currents to their advantage.
Feeding
Thalassarche melanophris are opportunistic feeders, consuming a wide range of prey, including fish, squid, and crustaceans. They primarily rely on their keen eyesight to locate prey, often diving into the ocean to catch their food. They are known to dive to depths of up to 10 meters (33 feet) in pursuit of prey. Their foraging behavior can vary depending on the availability of food, and they may also scavenge for food opportunistically.
