What is a Black-footed Albatross and what does it look like?

Watching an albatross fly is a breathtaking sight. These giant feathered seabirds have the largest wingspan of any known bird on the planet. Wingspan is measured with the bird in flight and wings fully extended, from the tip of one wing across the body of the bird to the tip of the other wing. The extended arm/wingspan of the average fifth grader, from fingertip to fingertip, is roughly 1.4 m (4.6 feet). The arm span of basketball star Michael Jordan is 2.1 m (6.9 feet). The wingspan of the Wandering albatross, the largest species of albatross, is 3.5 m (11.5 feet). The wingspan of the Black-footed albatross, one of the two dozen different species of albatross, is shorter, only measuring the distance of Michael Jordan's arm span. The formidable wingspan of these giant birds allows them to ride the wind currents above the ocean for hours at a time, without landing or even flapping their wings.

The Black-footed albatross has dark brown feathers (plumage) with a white area around the base of the bill. Its wings are long and narrow and it has a wingspan of about 1.9m-2.2m (76-85 inches). The males are slightly larger and have a longer bill. They have a keen sense of smell and can find food far across the ocean. As the Black-footed albatross nests in hot climates, it has developed ways of staying cool. The head of a Black-footed albatross has a large network of blood vessels which dilate to keep it cool. Similar to school children everywhere, they deal with the hot, sandy beaches by hopping from one foot to the other. There is a valve in its nose that stops water from passing into its airways when it dives in the ocean. It acts like a nose plug. They are clumsy in takeoff from land, running downhill with their wings outstretched into the wind. If the wind is not right, they may be stranded on the islands for a while. They also need a strong wind when taking off from the surface of the ocean.

Where do Black-Footed Albatross Live and Breed and What do they Eat?

This seabird spends most of its life soaring and gliding in the sky or floating on the North Pacific Ocean, coming to land only to breed in large colonies on the Northwestern Hawaiian Islands. They mate for life, but if a mate dies, they will find another. Nests are made up of pieces of grass, sand, and shrubs and are built in open spaces near beaches. On some islands plants are taking over these open sandy spaces and reducing the nesting areas for the birds. The breeding pairs lay a single egg and the parents take turns incubating it for 9-10 weeks. During this time, they sometimes fast for 2-3 weeks at a time and during incubation drop one quarter of their body weight. After the chicks hatch in late January or early February, both parents will take turns feeding at sea and returning to feed the chick every week or so. Some of their breeding islands are infested with rats and the rats eat the eggs and small chicks. When the chick is approximately 4 months-old, they lose weight, as they start to put more body energy into growing feathers and learning to fly. The Black-footed albatross must be 5-7 years-old before breeding, and they are at sea all that time.

Black-footed albatross eat the eggs of the flying fish, as well as squid. They sometimes follow ships, with the hope of getting a handout or finding garbage.

What are Some Threats to the Black-Footed Albatross Population?

As they are surface feeders, Black-footed albatross are affected by marine plastic pollution, eating other things floating in the ocean, such as plastic bottle caps, discarded cigarette lighters, six-pack plastic rings, rubber bands, balloons, and plastic toys. Ocean currents collect this garbage in various places in the world's oceans. One such place is north of the Hawaiian Island - the middle of the feeding ground for the Black-footed albatross. They fly as far as the west coast of California to feed, and they feed during the day, as their eyesight is too poor to see at night. The Black-footed albatross drinks sea water and gets rid of the extra salt through glands located above their eyes. They frequently are caught on the longline hooks set out for catching swordfish in Hawaii. In the 1800s all the albatrosses were hunted for their feathers and down which were used in the making of women's hats. The Albatross is commemorated in a famous poem "The Rime of the Ancient Mariner" by Samuel Taylor Coleridge.
