  • History and Causes of the Extirpation of the Providence Petrel (Pterodroma Solandri) on Norfolk Island
    246 Notornis, 2002, Vol. 49: 246-258 0029-4470 O The Ornithological Society of New Zealand, Inc. 2002 History and causes of the extirpation of the Providence petrel (Pterodroma solandri) on Norfolk Island DAVID G. MEDWAY 25A Norman Street, New Plymouth, New Zealand [email protected] Abstract The population of Providence petrels (Pterodroma solandri) that nested on Norfolk Island at the time of 1st European settlement of that island in 1788 was probably > 1 million pairs. Available evidence indicates that Europeans harvested many more Providence petrels in the years immediately after settlement than previously believed. About 1,000,000 Providence petrels, adults and young, were harvested in the 4 breeding seasons from 1790 to 1793 alone. Despite these enormous losses, many Providence petrels were apparently still nesting on Norfolk Island in 1795 when they are last mentioned in documents from the island. However, any breeding population that may have survived there until 1814 when Norfolk Island was abandoned temporarily was probably exterminated by the combined activities of introduced cats and pigs which had become very numerous by the time the island was re-occupied in 1825.

TAYLOR Research & Development Group, Department of Conservation, P.O. Box 10420, Wellington 6143, New Zealand Abstract An appraisal of the conservation status of the post-1800 New Zealand avifauna is presented. The list comprises 428 taxa in the following categories: ‘Extinct’ 20, ‘Threatened’ 77 (comprising 24 ‘Nationally Critical’, 15 ‘Nationally Endangered’, 38 ‘Nationally Vulnerable’), ‘At Risk’ 93 (comprising 18 ‘Declining’, 10 ‘Recovering’, 17 ‘Relict’, 48 ‘Naturally Uncommon’), ‘Not Threatened’ (native and resident) 36, ‘Coloniser’ 8, ‘Migrant’ 27, ‘Vagrant’ 130, and ‘Introduced and Naturalised’ 36. One species was assessed as ‘Data Deficient’. The list uses the New Zealand Threat Classification System, which provides greater resolution of naturally uncommon taxa typical of insular environments than the IUCN threat ranking system. New Zealand taxa are here ranked at subspecies level, and in some cases population level, when populations are judged to be potentially taxonomically distinct on the basis of genetic data or morphological observations.

  • Avifauna from the Emily Bay Settlement Site, Norfolk Island: a Preliminary Account
    © Copyright Australian Museum, 2001 Records of the Australian Museum, Supplement 27 (2001): 85–100. ISBN 0 7347 2305 9 Avifauna from the Emily Bay Settlement Site, Norfolk Island: A Preliminary Account RICHARD N. HOLDAWAY1 AND ATHOLL ANDERSON2 1 Palaecol Research, PO Box 16569, Christchurch, New Zealand [email protected] 2 Department of Archaeology & Natural History, Research School of Pacific and Asian Studies, Australian National University, Canberra ACT 0200, Australia [email protected] ABSTRACT. The avifauna of the Emily Bay settlement site, Norfolk Island, southwest Pacific, is described. Most of the remains, which consisted of nearly 10,000 identifiable bones (mostly fragmentary) and several thousand unidentifiable elements and fragments, were of several species of petrel and shearwater (Procellariiformes) and boobies (Sulidae), but some land birds were also represented in small numbers. Two species of migratory wading bird (Charadriiformes) were identified in the deposits, but no terns, which are dominant members of the present avifauna. The taphonomy of the remains indicates intensive use of birds as food, but some material of other than cultural origin was also present. Remains were not distributed evenly throughout the excavated parts of the site, and were concentrated in areas where other evidence such as post holes and fires scoops indicated points of occupation. Some species that are present on the island and palatable were not represented in the collections: possible reasons for their absence are canvassed. An estimate of the biomass is presented, with the proviso that the variation in density of deposition made extrapolation to the remainder of the site problematic. The size of the sample, the preservation of elements such as vertebrae of small petrels, and the good condition of material of apparent natural (non-cultural) origin indicate that the collection represents a good sample of the avifauna used as food by the Polynesian inhabitants of Emily Bay.

  • Status and Occurrence of Murphy's Petrel (Pterodroma Ultima) in British Columbia. by Rick Toochin and Louis Haviland. Submitte
    Status and Occurrence of Murphy’s Petrel (Pterodroma ultima) in British Columbia. By Rick Toochin and Louis Haviland. Submitted: April 15, 2018. Introduction and Distribution The Murphy’s Petrel (Pterodroma ultima) is a seldom seen seabird species that is listed by Bird Life International (2016) and IUCN (2016) as Near Threatened. This species breeds on islands of the Tropical Pacific Ocean from the Pitcairn Island group (Henderson Island, Oeno Island, and Ducie Island) (Murphy and Pennoyer 1952); the Tuamotu Island group (Mururoa Island and Fangataufa Island); islets of Rapa (Austral group) (Garnett 1984); and Manui in Gambier group (Thibault 1988); Easter Island and Salas y Gomez, Chile (Flores et al. 2014); and possibly on Cook Island (Gill 1996); and the Juan Fernandez Islands (Flood et al. 2016). In the Pitcairn Islands, an estimated 2,500 (± 500) bred on Henderson, 12,500 (± 2,500) on Oeno, and 250,000 (± 29,000) on Ducie (Brooke 1995). Following rat eradication on Oeno in 1997, the population there had grown to at least 25,000 pairs in 2013 (IUCN 2016) In the Tuamotu Islands, colonies occur on Mururoa and Fangataufa (Holyoak and Thibault 1984), although these may have disappeared owing to nuclear tests and the recent construction of an airstrip (IUCN 2016). In the Austral Islands, it breeds only on a limited number of islets off Rapa where the population was estimated at 10-100 pairs in 1990 (Thibault and Varney 1991). In the Gambier Islands, proof of breeding was found for the first time on Manui and numbers were estimated at 5-10 pairs (Thibault and Bretagnolle 1999).

Reproductive success of the Providence Petrel Pterodroma solandri on Lord Howe Island, Australia. Marine Ornithology 35: 21–28. The only significant breeding locality of the Providence Petrel Pterodroma solandri is Lord Howe Island, Australia, where the population is considered Vulnerable. During the 2000 and 2001 breeding seasons, data were collected on hatching, fledging and breeding success, and on egg and chick mortality. Annual breeding success was 34%–36% in burrows that were visited repeatedly and among adults and chicks handled at least once, and 54% in burrows that were visited only twice and contents not handled. The breeding success of individual adults was positively correlated with body condition, the relationship being stronger for males than for females. Egg losses occurred throughout the incubation period, but chick losses were concentrated within the first four weeks from hatching. Egg and chick mortality were strongly correlated with the distance of the nest from the burrow entrance, with more losses occurring in nests close to the entrance.

    COORDINATED CONSERVATION PLAN Lord Howe Island 1 Description Lord Howe I. Group, a volcanic island chain in the Tasman Sea. Formerly connected, via the Lord Howe Rise, to New Zealand and also has close affinities to Norfolk I. The vegetation is rainforest and cloud forest and scrub, swamp forest, mangrove forest coastal and cliff-top scrub, inland scrub and herbland, tussock grassland, and shoreline and beach vegetation (Pickard, 1983). Ten species of bird have become extinct as a result of hunting , introduced predators and competitors. 2 IBRA Regions Not applicable. crowned Parakeets were hunted to extinction. The 3 Core taxa self-introduced Sacred Kingfishers and endemic Pied Currawongs, killed as they were believed to kill Extinct poultry, have proved more resilient. White Gallinule A second suite of species, Lord Howe Gerygone, Grey White-throated Pigeon (Lord Howe Island) Fantail, Vinous-tinted Thrush, Robust White-eye and Red-crowned Parakeet (Lord Howe Island) Tasman Starling, and probably Pycroft's Petrel, which Southern Boobook (Lord Howe Island) is known only from subfossils, became extinct after Lord Howe Gerygone Black Rats Rattus rattus were accidentally introduced Grey Fantail (Lord Howe Island) from a wrecked ship in 1918. Rats are also thought to have eliminated Kermadec Petrels, Little Shearwaters Vinous-tinted Thrush and White-bellied Storm-Petrels from the main island Robust White-eye but they persist on Ball's Pyramid, Roach I. and Tasman Starling (Lord Howe Island) associated islets. Attempts to control the rats by Locally Extinct introduction of the Masked Owl possibly contributed Pycroft's Petrel to extinction of the local subspecies of Boobook.
