Males must perform a complicated courtship dance to win a mate. The females can afford to be picky, so if a male's sequence of honks, whistles, wiggles and neck thrusts doesn't impress her, she'll just move on to the next suitor.Ī courting Laysan albatross pair. And until the young males can master the choreography, they won't find a mate, he said. For the Laysan albatross, the dance has 24 separate, complex steps, and it takes years for males to learn them all, Tyler said. All species of albatross have some sort of complicated mating dance. Albatrosses mate for life, but aren't exclusiveīecause albatrosses mate for life, picking the right partner is a major decision. All seabirds have a gland above their eyes that functions like a miniature kidney, allowing them to drink salt water and excrete it through the tip of their beak, according to the Travis Audubon Society. It's possible the large bird just waits until a squid swims up to the surface, but a more convincing hypothesis is that the birds are actually eating squid bits that have been vomited up by whales, as described in a 1994 study published in the journal Antarctic Science.Īfter a meal of whale upchuck, an albatross might wash that down with some refreshing seawater. The wandering albatross can only dive about 2 to 3 feet (0.6 to 1 m) into the ocean, yet based on an analysis of its diet, scientists are pretty sure the wandering albatross eats squid that live deeper in the water, and are too big for an albatross to convincingly take down.

According to Breck Tyler, a lecturer at the University of California, Santa Cruz and retired research scientist who studied the Laysan albatross colony on Midway Atoll for decades, there are other Laysan albatrosses just a few years younger than Wisdom, so 'she's probably not an outlier.' That makes her at least 66 years old, but she's likely older, and she's still going strong - as of 2018 she was still raising chicks, NPR reported.

The oldest wild bird in the world is a Laysan albatross ( Phoebastria immutabilis) named Wisdom, who was tagged in 1956 at the Laysan albatross colony at Midway Atoll in the North Pacific Ocean when she was already a mature adult.

'It's an accepted fact because of their movements, they have to sleep.'Ī wandering albatross glides gracefully over the ocean. And, based on microchip-tracked movements of albatrosses, 'they can for hours on end, and so it is theorized that they do sleep on the wing,' Angel said. A 2016 study published in Nature Communications described how a distant cousin of the albatross, the frigatebird, has many, seconds-long periods of sleep while flying, suggesting that sleeping in the air is definitely possible for other long-distance traveling seabirds.

In fact, it's the tiny alpine swift, not the albatross, that holds the record for non-stop distance flying, as reported in a 2013 study published in the journal Nature Communications.Īs for sleep, Angel said that it's very likely that albatrosses sleep on the wing.

The birds also use something called 'dynamic soaring,' which involves changing the angle of their wings relative to the wind, to maximize the lift generated - a similar technique could help unmanned research aircraft stay aloft for months, the Independent reported. With near constant wind in their environment, albatrosses are able to 'lock their elbow joints and literally just fix their wings and just glide,' Angel said. This latitude range is 'called the 'roaring 40s' and 'furious 50s' for a reason,' said Andrea Angel, the Albatross Task Force manager with Birdlife South Africa, a nonprofit organization dedicated to bird conservation.
