Wedge-tailed shearwater/Conservation status
Are shearwaters native to Hawaii?
Hawaiian Name: ʻUaʻu kani Wedge-tailed Shearwater colonies occur on almost every island in the Hawaiian Chain, where they nest at low-elevation sites in burrows under sand, soil, tree roots or in loose rocks. Wedge-tailed Shearwaters also breed sporadically on Lanaʻi, Kahoʻolawe, and Hawaiʻi.
Where do wedge-tailed shearwaters live?
Wedge-tails breed widely in the tropical and subtropical waters of the Indian and Pacific Oceans.
What do wedge-tailed shearwater eat?
Wedge-tailed shearwaters feed pelagically on fish, squid, and crustaceans. Their diet is 66% fish, of which the most commonly taken is goatfish.
What noise does a shearwater make?
These shearwaters fly quickly over land when flying to or from nesting areas; thus, in still air, a “whooshing” noise can be heard as they pass close-by. They also make noise as they crash-land in the usually thick vegetation near their burrow entrances.
Do shearwaters fly at night?
Many species spend the day feeding out at sea and only return to their nests at night. Some species, like the short-tailed shearwater, gather together in the afternoon before flying ashore at dusk.
Why are shearwaters endangered?
Serious population declines are attributed to degraded island habitat, depredation by introduced land predators, light pollution, and collisions with power lines. It is estimated that the Newell’s shearwater’s population has been declining at rates far exceeding 50 percent over the species’ last three generations.
What animals eat shearwaters?
Do Shearwaters have any natural predators? This depends on the species and where its breeding grounds are located. For example the Townshend’s Shearwaters breed on Socorro Island where they are vulnerable to feral cats. Other species and locations may also be vulnerable to rats, falcons, goats, or pigs.
Why are shearwaters called mutton birds?
Shearwaters earned their name by their ability to cut – or shear – the water with their wings, although until recently they were known as ‘muttonbirds’. This name was given to them by early European settlers, who killed the birds for food and found that their flesh tasted like mutton.
How do shearwaters sleep?
They are nocturnal at the colonial breeding sites, preferring moonless nights to minimize predation. They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg.
Which bird Cannot walk?
Loons and Grebes do not walk. It is physically impossible for these birds due to the fact that their legs are positioned towards the rear of their body. Their legs were built for swimming under water.

Wedge-tailed Shearwater. Wedge-tails are dark brown to brownish-grey above with white underparts, except dark wing margins and undertail-coverts. They have a wedge-shaped tail and a slender, slate-grey hooked bill. Legs and feet are flesh colored. Loud groans, moans and wails resulted in island residents giving them the name “moaning bird”.
What does a Shearwater bird look like?
Large but light-bodied shearwater with rather broad wings and a long, wedge-shaped tail often held closed in a point. Fairly common in warm tropical waters and at times visible from shore. Occurs locally in flocks of hundreds; elsewhere occurs in smaller numbers. Usually seen with feeding flocks of other seabirds.
