Specific objectives were to collect photo-point and ground-truthing data at Campbell and grey-headed albatross colonies, repeat whole-island counts of breeding Northern giant petrels, collect GLS trackers from Southern royal albatrosses, use sound recorders to record burrowing petrel distribution and check the bands of all banded birds seen. Photo-points for Campbell albatross and grey-headed albatross (Thalassarche impavida and T. chrysostoma) were revisited to take a new set of photographs for population monitoring. These photo-points have been used for counts since 1987, but some colonies have been photographed since the 1940s.

  • 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.

  • Behavior and Attendance Patterns of the Fork-Tailed Storm-Petrel
    BEHAVIOR AND ATTENDANCE PATTERNS OF THE FORK-TAILED STORM-PETREL THEODORE R. SIMONS Wildlife Science Group, Collegeof Forest Resources, University of Washington, Seattle, Washington 98195 USA ABSTRACT.--Behavior and attendance patterns of breeding Fork-tailed Storm-Petrels (Ocea- nodromafurcata) were monitored over two nesting seasonson the Barren Islands, Alaska. The asynchrony of egg laying and hatching shown by these birds apparently reflects the influence of severalfactors, including snow conditionson the breedinggrounds, egg neglectduring incubation, and food availability. Communication between breeding birds was characterized by auditory and tactile signals.Two distinct vocalizationswere identified, one of which appearsto be a sex-specific call given by males during pair formation. Generally, both adults were present in the burrow on the night of egg laying, and the male took the first incubation shift. Incubation shiftsranged from 1 to 5 days, with 2- and 3-day shifts being the most common. Growth parameters of the chicks, reproductive success, and breeding chronology varied considerably between years; this pre- sumably relates to a difference in conditions affecting the availability of food. Adults apparently responded to changes in food availability during incubation by altering their attendance patterns. When conditionswere good, incubation shifts were shorter, egg neglectwas reduced, and chicks were brooded longer and were fed more frequently. Adults assistedthe chick in emerging from the shell. Chicks became active late in the nestling stage and began to venture from the burrow severaldays prior to fledging. Adults continuedto visit the chick during that time but may have reducedthe amountof fooddelivered. Chicks exhibiteda distinctprefledging weight loss.Received 18 September1979, accepted26 July 1980.

  • The Stormy Petrel (Procellaria Pelagica)
    THE 0.8~ O.SEMI-ANNUAL. 37 THE STORMYPETREL. Procellaria Pelagica. DY W. RAINE, TORONTO, CANADA This interesting little bird, though rare in North America, is plen- tiful on the British side of the Atlantic Ocean. It is supposed to be the smallest web-footed bird known, and seldom comes to shore ex- cept during the breeding season, when they resort to such places as the Stilly Islands, in the English Channel, and the islands of the Irish Sea; but their chief nesting places are in the Orkney and Shetland Islands, and St. Kilda and STORMY PETREL. the outer Hebrides. This bird is well known to sailors by the name of Mother Carey’s Chicken, and hated by them because it foretells an approaching storm. They are mostly seen in stormy weather, because the marine crea- tures, on which they feed, are tossed to the surface of the chopping waves, and can be easily picked up by the bird as it passes over the waves, pattering the water with its webbed feet, and flapping its wings so as to keep itself just above the surface. The name Petrel is given to these birds on account of its powers of walking on the water, as is related of St. Peter. This bird seems very happy during rough weather, and many a ship-wrecked sailor, while clinging half locausted to some floating wreckage, has envied this little bird of its powers of flight, as it traverses the rolling, seething billows with wonderful ease. It feeds on the little fish, crustaceaus and molluses which are found in abundance on the surface of the sea.

Report to NZ Deparment of Conservation. Parker Conservation, Dunedin pp 13. 1 Rexer-Huber | White-chinned petrels Summary The white-chinned petrel Procellaria aequinoctialis is one of the most frequently observed seabird species captured in fisheries bycatch, yet some populations remain virtually unstudied. In the New Zealand region, the priority programmes to fill key information gaps included surveying, tracking and collecting demographic data from white-chinned petrels in the Auckland Islands. Survey of the Campbell Island population and clarification of taxonomic uncertainty in the New Zealand region were secondary aims. The scope of this report is to summarise research findings, with focus on New Zealand populations of white-chinned petrels. An estimated 186,000 (95% CI: 131,000–248,000) white-chinned petrel pairs breed in the Auckland Islands, and the Campbell Island group supports around 22,000 (15,000–29,000) breeding pairs. The New Zealand region supports almost a third of white-chinned petrels globally, but population trends remain unknown. We establish population baselines that can be repeated for trend estimation. A tracking programme in the Auckland Islands has retrieved 40 geolocators from white-chinned petrels, which were analysed together with tracking data from all major island populations. NZ populations do not overlap at sea with populations from South Atlantic or Indian Ocean islands.

  • Geographic Variation in Leach's Storm-Petrel
    GEOGRAPHIC VARIATION IN LEACH'S STORM-PETREL DAVID G. AINLEY Point Reyes Bird Observatory, 4990 State Route 1, Stinson Beach, California 94970 USA ABSTRACT.-•A total of 678 specimens of Leach's Storm-Petrels (Oceanodroma leucorhoa) from known nestinglocalities was examined, and 514 were measured. Rump color, classifiedon a scale of 1-11 by comparison with a seriesof reference specimens,varied geographicallybut was found to be a poor character on which to base taxonomic definitions. Significant differences in five size charactersindicated that the presentlyaccepted, but rather confusing,taxonomy should be altered: (1) O. l. beali, O. l. willetti, and O. l. chapmani should be merged into O. l. leucorhoa;(2) O. l. socorroensisshould refer only to the summer breeding population on Guadalupe Island; and (3) the winter breeding Guadalupe population should be recognizedas a "new" subspecies,based on physiological,morphological, and vocal characters,with the proposedname O. l. cheimomnestes. The clinal and continuoussize variation in this speciesis related to oceanographicclimate, length of migration, mobility during the nesting season,and distancesbetween nesting islands. Why oceanitidsfrequenting nearshore waters during nestingare darker rumped than thoseoffshore remains an unanswered question, as does the more basic question of why rump color varies geographicallyin this species.Received 15 November 1979, accepted5 July 1980.

  • Management Plan for Antarctic Specially Protected Area No
    Measure 2 (2005) Annex E Management Plan for Antarctic Specially Protected Area No. 120 POINTE-GÉOLOGIE ARCHIPELAGO, TERRE ADÉLIE Jean Rostand, Le Mauguen (former Alexis Carrel), Lamarck and Claude Bernard Islands, The Good Doctor’s Nunatak and breeding site of Emperor Penguins 1. Description of Values to be Protected In 1995, four islands, a nunatak and a breeding ground for emperor penguins were classified as an Antarctic Specially Protected Area (Measure 3 (1995), XIX ATCM, Seoul) because they were a representative example of terrestrial Antarctic ecosystems from a biological, geological and aesthetics perspective. A species of marine mammal, the Weddell seal (Leptonychotes weddelli) and various species of birds breed in the area: emperor penguin (Aptenodytes forsteri); Antarctic skua (Catharacta maccormicki); Adélie penguins (Pygoscelis adeliae); Wilson’s petrel (Oceanites oceanicus); giant petrel (Macronectes giganteus); snow petrel (Pagodrama nivea), cape petrel (Daption capense). Well-marked hills display asymmetrical transverse profiles with gently dipping northern slopes compared to the steeper southern ones. The terrain is affected by numerous cracks and fractures leading to very rough surfaces. The basement rocks consist mainly of sillimanite, cordierite and garnet-rich gneisses which are intruded by abundant dikes of pink anatexites. The lowest parts of the islands are covered by morainic boulders with a heterogenous granulometry (from a few cm to more than a m across). Long-term research and monitoring programs of birds and marine mammals have been going on for a long time already (since 1952 or 1964 according to the species). A database implemented in 1981 is directed by the Centre d'Etudes Biologiques de Chize (CEBC-CNRS).
