  • Conservation Problems on Tristan Da Cunha Byj
    28 Oryx Conservation Problems on Tristan da Cunha ByJ. H. Flint The author spent two years, 1963-65, as schoolmaster on Tristan da Cunha, during which he spent four weeks on Nightingale Island. On the main island he found that bird stocks were being depleted and the islanders taking too many eggs and young; on Nightingale, however, where there are over two million pairs of great shearwaters, the harvest of these birds could be greater. Inaccessible Island, which like Nightingale, is without cats, dogs or rats, should be declared a wildlife sanctuary. Tl^HEN the first permanent settlers came to Tristan da Cunha in " the early years of the nineteenth century they found an island rich in bird and sea mammal life. "The mountains are covered with Albatross Mellahs Petrels Seahens, etc.," wrote Jonathan Lambert in 1811, and Midshipman Greene, who stayed on the island in 1816, recorded in his diary "Sea Elephants herding together in immense numbers." Today the picture is greatly changed. A century and a half of human habitation has drastically reduced the larger, edible species, and the accidental introduction of rats from a shipwreck in 1882 accelerated the birds' decline on the main island. Wood-cutting, grazing by domestic stock and, more recently, fumes from the volcano have destroyed much of the natural vegetation near the settlement, and two bird subspecies, a bunting and a flightless moorhen, have become extinct on the main island. Curiously, one is liable to see more birds on the day of arrival than in several weeks ashore. When I first saw Tristan from the decks of M.V.

  • DIET and ASPECTS of FAIRY PRIONS BREEDING at SOUTH GEORGIA by P.A
    DIET AND ASPECTS OF FAIRY PRIONS BREEDING AT SOUTH GEORGIA By P.A. PRINCE AND P.G. COPESTAKE ABSTRACT A subantarctic population of the Fairy Prion (Pachyprzla turtur) was studied at South Georgia in 1982-83. Full measurements of breeding birds are given, together with details of breeding habitat, the timing of the main breeding cycle events, and chick growth (weight and wing, culmen and tarsus length). Regurgitated food samples showed the diet to be mainly Crustacea (96% by weight), fish and squid comprising the rest. Of crustaceans, Antarctic krill made up 38% of items and 80% by weight. Copepods (four species, mostly Rhincalanus gigas) made up 39% of items but only 4% by weight; amphipods [three species, principally Themisto gaudichaudii made up 22% of items and 16% by weight. Diet and frequency of chick feeding are compared with those of Antarctic Prions and Blue Petrels at the same site; Fairy Prions are essentially intermediate. INTRODUCTION The Fairy Prion (Pachyptila turtur) is one of six members of a genus confined to the temperate and subantarctic regions of the Southern Hemisphere. With the Fulmar Prion (P. crassirostris), it forms the subgenus Pseudoprion. Its main area of breeding distribution is between the Antarctic Polar Front and the Subtropical Convergence. It is widespread in the New Zealand region, from the north of the North Island south to the Antipodes Islands and Macquarie Island, where only about 40 pairs survive (Brothers 1984). Although widespread in the Indian Ocean at the Prince Edward, Crozet and Kerguelen Islands, in the South Atlantic Ocean it is known to breed only on Beauchene Island (Falkland Islands) (Strange 1968, Smith & Prince 1985) and South Georgia (Prince & Croxall 1983).

We tried to clarifythese issues with 496bp sequencesfrom the mitochondrialcytochrome-b gene of 12 taxa representingthree putative subspecies of Pseudobulweria,seven species in six othergenera of the Procellariidae(fulmars, petrels, and shearwaters),and onespecies each from the Hydrobatidae(storm-petrels) and Pelecanoidi- dae (diving-petrels).We alsoinclude published sequences for two otherpetrels (Procellaria cinereaand Macronectesgiganteus ) and use Diomedeaexulans and Pelecanuserythrorhynchos as outgroups.Based on thepronounced sequence divergence (5 to 5.5%)and separate phylo- genetichistory from othergenera that havebeen thought to be closelyrelated to or have beensynonymized with Pseudobulweria,we conclude that the genusis valid, and that the MascarenePetrel (Pseudobulweria aterrima)

  • Conservation Services Programme Project MIT2015-02: Mitigating
    Conservation Services Programme Project MIT2015-02: Mitigating seabird captures during hauling on smaller longline vessels J. P. Pierre 6 April 2018 Executive summary ___________________________________________________________________________ Seabird captures in longline fisheries may occur on the set, soak or haul. Bycatch reduction measures are best developed, tested and implemented for reducing seabird captures occurring during longline sets. Measures affecting the nature and extent of haul captures, and mitigation approaches to reduce those captures, are not well-known. Further, the difficulty of accurately identifying captures as occurring on the haul means that live seabird captures are typically used as a proxy for haul captures in bycatch datasets. A global review shows four broad categories of mitigation used during longline hauling: physical barriers, measures that reduce the attractiveness of the haul area, deterrents, and operational approaches that are part of fishing. Of devices that operate as physical barriers to seabirds, bird exclusion devices, tori lines and towed buoys have been tested and proven effective in reducing seabird interactions with hauled longline gear. Discharging fish waste such that seabirds are not attracted to the hauling bay is another effective measure, and seabird abundance around vessels is reduced by retaining fish waste during hauling. While a number of deterrents and ad hoc or reactive approaches to reducing haul captures have been discussed in the literature (e.g. water sprays), these have generally not been empirically tested. Information collected by government fisheries observers on 73 bottom longline and 60 surface longline trips that have occurred since 1 October 2012 on New Zealand vessels < 34 m in overall length showed that most of these measures are in place here.
