What other name is a shearwater commonly known?

What is a fluttering shearwater?

The fluttering shearwater, with its distinctive, ‘flutter-glide’ flight, is a ubiquitous seabird of inshore waters in the top half of New Zealand, especially in the northern-eastern North Island and Marlborough Sounds-Cook Strait regions. It is often seen in flocks, sometimes numbering thousands of birds, moving rapidly while foraging.

Why is Townshend’s shearwater endangered?

Townshend’s shearwater faces the greatest threat of extinction of all shearwaters, because it breeds in a single location, Socorro Island, where many individuals are preyed upon by feral cats. A population study performed in 2008 documented fewer than 100 breeding pairs on the island.

What do fluttering shearwater eat?

The fluttering shearwater’s diet consists mostly of schooling fish (such as pilchards, trevally, mackerel, pilchards, sprats, etc.), small pelagic crustacea (krill etc.) and squids. This prey is caught through two methods, either surface seizing and pursuit diving.

What time of year do fluttering shearwaters breed?

Fluttering shearwaters start to breed when 4–10 years old and breeding season date August and to January. The type of nest is burrow and the nest chamber is made of dead leaves, grass, feathers and shoots.

Where do fluttering shearwaters live in New Zealand?

Fluttering shearwaters breed on many offshore islands throughout northern New Zealand, with large colonies on Three Kings, Moturoa, Motuharakeke (Cavalli), Bream, north-west Chickens, Mercury and Alderman Islands. In the Marlborough Sounds there are large colonies on Trio and Long Islands.

Are there flesh-footed shearwaters in Australia?

the flesh-footed shearwater returns from the seas off Japan and Siberia to the same nesting burrows on Lord Howe Island – this species is listed as vulnerable in NSW short-tailed shearwaters breed on islands along the eastern and southern coastlines of Australia, from the central coast of NSW to Western Australia.

Is there a similar bird to the Hutton’s shearwater?

Similar species: fluttering shearwater is a very similar-looking, but slightly smaller bird which breeds in the Marlborough Sounds and further north, and has a range that completely overlaps the New Zealand range of Hutton’s shearwater.

What is Townsend’s shearwater?

Townsend’s shearwater ( Puffinus auricularis) is a rare seabird of the tropics from the family Procellariidae . Its relationships are unresolved.

Where is the first protected area for the marsh antwren?

The first protected area for the Critically Endangered Marsh Antwren was established in São Paulo state, Brazil, with ABC support. The new reserve spans 5,860 acres and was declared by the municipality of Guararema working with the local organization Guaranature and SAVE Brasil.

Are fluttering shearwaters monogamous?

However, it is known that fluttering shearwaters, like most birds, are monogamous in that they breed with one mate throughout their life. Fluttering shearwaters start to breed when 4–10 years old and breeding season date August and to January. The type of nest is burrow and the nest chamber is made of dead leaves, grass, feathers and shoots.

What does a fluttering shearwater look like?

Fluttering shearwater has pinkish-brown legs and feet with bark webs, feet extend beyond the tail in flight. The bill is long and thin with dark colour. The tail is fan-shaped and short in flight and it has mixed colour – dark brown and white. Moult start from late January and the dark upper surfaces fade to mid-brown quickly.

How does the Shearwater move?

It is often seen in flocks, sometimes numbering thousands of birds, moving rapidly while foraging. Fluttering shearwaters feeds in association with schools of fish (e.g. kahawai, trevally) or in massive groups at the surface on crustaceans; and at times, resting in large, dense rafts.

What is the habitat of fluttering shearwater?

The habitats of fluttering shearwater are marine and terrestrial habitats, including coastal and marine areas, scrubland and forest. They are most commonly found in subtropical waters and warm water (24 ℃) of intermediate to high salinity (35%). Common on inshore areas that are easy to enter harbours, inlets, bays and straits.

What is an Audubon Shearwater bird?

The Audubon’s Shearwater bird, (Puffinus lherminieri) also known as the dusky-backed shearwater, is a common seabird of the tropics from the family Procellariidae. Audubon’s Shearwater is a medium sized sea bird commonly seen from the yachts around the Galapagos islands.

Do Audubon’s shearwaters migrate?

Unlike the larger shearwaters, adult Audubon’s shearwaters are not thought to wander much or undertake great migrations. However, their young birds do so before breeding, and western Indian Ocean birds may gather in large numbers at the upwelling zone in the Arabian Sea.

How does the IUCN List A bird species as endangered?

If lawmakers establish regulations that bar the logging company from continuing to fell trees in the area, then the IUCN will list the bird species as “endangered” because they understand the reason for the decline, and it is stopped. A taxon’s population size is reduced by 30 percent or more over 10 years or three generations, whichever is longer.

Is the great hornbill a endangered species?

Hornbill populations are decreasing worldwide, and the great hornbill is classified as vulnerable on the International Union for Conservation of Nature’s Red List of Threatened Species.

Where do shearwater birds breed in Australia?

The only breeding site in eastern Australia is on Lord Howe Island. Populations in recent decades have been in decline. In 2005, marine biologist Jennifer Lavers discovered 79% of shearwater chicks had plastic in their stomachs, fed to them by their parents which scooped the plastic up as it floated on the surface.

When do Hutton’s shearwaters migrate?

Upon fledgling (mid-March to early April) chicks migrate with other Hutton’s shearwaters to the fish-rich coastal waters off Australia. Immature birds remain there until returning to Kaikoura to breed at 3-4 years of age.

Are there Hutton’s shearwaters in New Zealand waters?

The distribution of Hutton’s shearwaters within New Zealand waters is poorly understood as few at-sea observers attempt to distinguish Hutton’s shearwaters from the similar fluttering shearwater.

What can fishers do to protect Hutton’s shearwater?

Hutton’s shearwater feed on fish, so are vulnerable to becoming tangled in set nets and drowning. Fishers can help protect the seabirds by monitoring set nets closely.
