The Northwestern Hawaiian Islands are home to 99.7% of the population. It nests on open sandy or grassy expanses of islands, with 94% of breeding pairs on Laysan Island and Midway Atoll, as well as on other small Hawaiian Islands, the bigger islands of Oahu and Kauai, and a few sites off Japan and Mexico. These species usually dwell in open water areas but move to islands during the time of mating. This species spends much time at sea, circling around for many years. These birds can fly for many days high in the sky and do not flap their wings once. During these four or five years, they form pair bonds with a mate that they will keep for life. This time investment by the parents may explain the long courtship; both parents want to be sure the other is serious. [18], The Laysan albatross feeds predominantly on cephalopods,[19] but also eats fish, crustaceans, and other invertebrates.[20]. This albatross has blackish-gray upperwing, mantle, back, upper rump, and tail, and its head, lower rump, and underparts are white. All but 0.3% of the breeding population is found among the Northwestern Hawaiian Islands, particularly the islands of Midway and Laysan. Once it leaves the nest and heads out to sea, a Laysan albatross stays at sea for 3-5 years, after which it returns to the nesting colony to search for a mate. They return only after five years or so in order to breed. [22] The species is still vulnerable to longline fisheries and the ingestion of floating plastics due to high rates of plastic pollution. [5] Males, which weigh 2.4 to 4.1 kg (5.3–9.0 lb), are larger than females, which weigh 1.9 to 3.6 kg (4.2–7.9 lb). The chick takes about 160 days to fledge. Your email address will not be published. Only during the time of mating, they stay on the ground. By nature, they are monogamous. In the sky, these birds tend to travel for long distances in a gliding movement. Fish and Wildlife Service estimated the total worldwide population for breeding pairs in 2003-2004 as 630,000 pairs. The Laysan albatross has a wide range across the North Pacific, with 16 nesting sites. It has a black smudge around the eye, and its underwing pattern varies between individuals, with some having narrower black margins and variable amounts of black in the und… Some Interesting Facts about Laysan Albatross. This helps them to locate residence on the ground during the night time, when they are awake, and also be aware of the predators at the same time. The Mexican population has been increasing since its inception.[4]. Long line fishing should be forbidden by laws to save these species. In the North Pacific, it is simple to separate from the other relatively common albatross, the all black black-footed albatross. It nests on islands in the tropical Pacific, but will feed in Japan, California or the Aleutian Islands. Occasionally, the birds form same-sex pairs consisting of two females. Current threats today are the longline fisheries. It is named for Laysan, one of its breeding colonies in the Northwestern Hawaiian Islands. The Laysan albatross averages 81 cm (32 in) in length and has a wingspan of 195 to 203 cm (77–80 in). These birds breed in colonies, which are sometimes large. Feral cats are known to prey on nesting birds and chicks on some of the more newly colonized islands. The Laysan albatross was first described as Diomedea immutabilis by Lionel Walter Rothschild, in 1893, on the basis of a specimen from Laysan Island.[3]. Juveniles have a gray bill and a dark upper rump. The young albatross take 160 days to fly. [citation needed]. The sex ratio comprising males out of females is 2-3.
