  In calm weather the Sooty Shearwater flies low over the ocean with quick, stiff beats of its narrow wings; in windy conditions, it glides and scales effortlessly over the waves. Sociable at sea, it is often seen in gatherings of hundreds or even thousands, flying in long lines or resting in dense rafts on the water. Although it is often the most abundant seabird off the coast of California. The sooty shearwater (Ardenna grisea) is a medium-large shearwater in the seabird family Procellariidae. Ardenna was first used to refer to a seabird by Italian naturalist Ulisse Aldrovandi in , and grisea is medieval Latin for "grey".. In New Zealand, it is also known by its Māori name tītī, and as muttonbird, like its relatives the wedge-tailed shearwater (A. pacificus) and the Class: Aves. Voice: sooty shearwaters are usually silent at sea; most calls are given by birds at night on the breeding colonies, though occasional calls are given by birds flying over breeding colonies at night. The main call is a loud, rhythmically repeated slightly hysterical coo-roo-ah which is generally given by duetting birds from within burrows or on.   Sooty shearwater km (39, miles) in a roundtrip journey each year. It is the longest recorded animal migration. Contrary to previous assumptions, sooty shearwaters do not make a big pan-Pacific sweep to cover all of the feeding areas in the Northern Hemisphere.

Its bill is dark and when seen close up, there is a pale band along the underneath of the wings. This Sooty Shearwater is taking off with little wind (notice the smooth sea) forcing it to run further. Even flying in an almost straight line the shearwater alternates flapping with gliding. Watch closely and you may notice a shearwater catch up and pass a boat going 25 knots. One study found Sooty shearwaters migrating nea km (40, mi) a year, which would give them the longest animal migration ever recorded electronically. Short-tailed shearwaters perform an even longer "figure of eight" loop migration in the Pacific Ocean from Tasmania to as far north as the Arctic Ocean off northwest Alaska. Sooty shearwater Smaller than great shearwaters are sooty shearwaters, which we most often spot in the Falklands and around Tierra del Fuego. Daphne du Maurier and Alfred Hitchcock received inspiration for their respective story and film, The Birds, from a reported incident of thousands of sooty shearwaters flying into objects and dying in the.

Dark brown seabird with silvery flashes on underwings. Smaller than most gulls. Wingbeats are quick and snappy but deep. In the North Pacific, very similar to Short-tailed Shearwater but slightly larger with longer bill and more gradually sloping forehead. Brown plumage reminiscent of Flesh-footed Shearwater but narrower-winged. Where common, seen from shore more frequently than other. But the occasional short-tailed shearwater strays across the Tasman Sea into New Zealand’s waters and is seen off Kaikoura over the summer. They look very similar to the sooty shearwater, but you can distinguish them by the colour of their underwing: the sooty shearwaters has a white underwing; the short-tailed shearwater greyish. 7 Stunning Shearwater Facts. The name “Shearwater” comes from the birds’ flight style of shearing across the fronts of waves with their wings held stiff. A study on Sooty Shearwaters found that they migrate in the range of 64, km in a single year, which gives them the longest migration ever recorded electronically of any animal on Earth.
