Often seen where whales are actively feeding or behind a fishing boat that is cleaning fish. A sanctuary-led research team found that this seabird species, which “summers” on islands in the southern South Atlantic and along the Patagonian shelf off Argentina December-February, uses the Gulf of Maine as a “winter” nursery during the months of approximately July-November. Migration. Mature birds continue on to the Tristan da Cunha Islands for breeding, while juvenile, non-breeding birds stay behind on the Patagonian shelf and older immatures, but still not breeding birds, roam the South Atlantic, as far as South Africa. Upon leaving their breeding burrows within the Tristan Islands they will migrate west towards the Patagonian Shelf edge, where they will gorge on the abundant small fish and squid species that are found in the rich waters. The great shearwater is a large brown-above and white-below shearwater. Migration In April and May, the Greater Shearwater leaves the breeding grounds and migrates north crossing the ocean to vacation in the north west Atlantic including the Gulf of Maine where we see large numbers of them on Stellwagen Bank. This trip is 6,000 miles each way and, if they're lucky, Great Shearwaters will complete this round trip every year for a 60-year lifetime. Great Shearwater (South Georgia Island, 22 March 2006).

A great many people have engaged with the debate … Great Shearwaters are very long distance migrants, as they breed on a few islands in the South Atlantic, and then move to the North Atlantic during the Northern Hemisphere summer. Migrates later in fall than other jaegers, especially young birds, with juveniles rarely seen south of the Arctic before October. I joined Michael Brothers of the Volusia County Marine Science Center on a pelagic seabird trip that would also serve as the release party for a Great Shearwater. A great shearwater flies over the ocean waters off the coast of Virginia Beach. Sooty Shearwater appears to be closely related to the Great and Short-tailed Shearwaters which are blunt-tailed, black-billed species with long, dark, hooked top mandible, but its precise relationships with those shearwaters are obscure.

Western coasts might be more productive than eastern coasts. Day 9 Carlton. LC Least Concern. The last month has seen a gradual intensification to migration. A great deal about the lives of many of the varieties of Shearwater is still a mystery due to their pelagic lifestyle (they live entirely at sea outside of breeding season) and the fact that they migrate so far so fast. World distribution: Great Shearwaters breed mainly in the Tristan da Cunha group where +5 million pairs nest and up to 3 million pairs on Gough Island. It covers a distance of 1300 km.

See photos and read more about seabird migration. Some seabirds travel very far distances, like the sooty shearwater, which GPS trackers have followed for more than 40,000 miles, figure-eighting across the Pacific Ocean, within just a year. Great Shearwater sketch. Great shearwaters breed in the South Atlantic Ocean on Gough Island, Inaccessible and Nightingale Islands (Tristan da Cunha group) and there is a small colony in the Falkland Islands. The Great Shearwater or Petrel The great shearwater or petrel ( Puffinus gravis) has a wingspan up to 118cm and weighs up to 1.1kg. (Pelagic relates to the open ocean.) White wing linings and thin, black bill. Names (38) Species names in all available languages. Access to the birds here is easier, as the same small fish like sandlance and capelin that attract the birds also attract whales and whale watchers. The great shearwater's relationships are unclear.

Pomarine Jaegers (Stercorarius pomarinus), also known as Pomarine Skuas, are predatory and pirate-like seabirds that will often steal prey from other birds. During migration, these birds follow a circular pattern. The Great Shearwater is a large seabird which breeds on Nightingale Island, Inaccessible Island, Tristan da Cunha and Gough Island.

The Great Shearwater’s migration off the southern tip of South America takes it east and up into the North Atlantic. The majority of the stranded birds were Great Shearwaters, which follow the Gulf Stream along the eastern U.S. coast to migrate between their breeding and feeding grounds. When healthy, shearwaters can dive more than 50 feet (15 meters) beneath the surface in pursuit of fish, propelled by their webbed feet and the beating of half-folded wings, but a rehabilitated bird may not be able to dive so deep.

Penguins migrate by swimming and cover a considerable distance of few hundred miles. The electronic tags recorded birds diving to depths as great as 68 meters (225 feet) to capture their prey. With some luck, it will gain strength at its North Atlantic feeding grounds, return to its breeding grounds much farther south, and then repeat the journey for years to come. Written by Bob Sundstrom This is BirdNote! General. View a larger version of the above slideshow here. It is one of the largest shearwaters seen. While Stellwagen Bank National Marine Sanctuary’s research project primarily focuses on understanding prey distribution, the long-lasting technology allowed the team to continue tracking many of the birds on their southward migration during our winter (the southern summer). High collocation of sand lance and protected top predators: implications for conservation and management.

In fact, they are nearly as clumsy and cumbersome as penguins (though not quite as bad.) The research provides further evidence of the importance of the Stellwagen Bank ecosystem to the local food web and to some of the area’s most iconic species in their critical juvenile stage. Adults leave breeding islands in April and move north rapidly, mostly along western side of Atlantic, becoming common off east coast of North America in June. Sooty Shearwater appears to be closely related to the Great and Short-tailed Shearwaters which are blunt-tailed, black-billed species with long, dark, hooked top mandible, but its precise relationships with those shearwaters are obscure.
