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. -

Wedge-tailed Shearwater Ardenna pacifica fallout patterns inform targeted management. Marine Ornithology 48: 245–254. Seabird fledglings are often attracted to artificial, bright lights, leading to their grounding. This phenomenon is termed “fallout” and is associated with an increased risk of mortality from land-based threats. This study evaluated temporal trends and spatial factors, such as fallout clustering near lights and proximity to colonies, to inform targeted management actions. Standardized surveys were conducted from 2002 to 2010 for Wedge-tailed Shearwater Ardenna pacifica (WTSH) fallout on the island of O‘ahu, Hawai‘i, USA. First, yearly fallout counts along the transect showed a two-year cycle and identified 25 November as the date with the highest fallout across years. Second, artificial lights and utility lines were present in 94% and 83% of fallout locations, leading to significantly higher fallout rates at these locations compared to random points along the transect. Third, fallout decreased significantly as the distance from the colonies increased and was negligible farther than 5 km from the nearest colony. -

Rare Birds in Iran in the Late 1960S and 1970S
Podoces, 2008, 3(1/2): 1–30 Rare Birds in Iran in the Late 1960s and 1970s DEREK A. SCOTT Castletownbere Post Office, Castletownbere, Co. Cork, Ireland. Email: [email protected] Received 26 July 2008; accepted 14 September 2008 Abstract: The 12-year period from 1967 to 1978 was a period of intense ornithological activity in Iran. The Ornithology Unit in the Department of the Environment carried out numerous surveys throughout the country; several important international ornithological expeditions visited Iran and subsequently published their findings, and a number of resident and visiting bird-watchers kept detailed records of their observations and submitted these to the Ornithology Unit. These activities added greatly to our knowledge of the status and distribution of birds in Iran, and produced many records of birds which had rarely if ever been recorded in Iran before. This paper gives details of all records known to the author of 92 species that were recorded as rarities in Iran during the 12-year period under review. These include 18 species that had not previously been recorded in Iran, a further 67 species that were recorded on fewer than 13 occasions, and seven slightly commoner species for which there were very few records prior to 1967. All records of four distinctive subspecies are also included. The 29 species that were known from Iran prior to 1967 but not recorded during the period under review are listed in an Appendix. Keywords: Rare birds, rarities, 1970s, status, distribution, Iran. INTRODUCTION Eftekhar, E. Kahrom and J. Mansoori, several of whom quickly became keen ornithologists. -

Seabirdswithin 370 km of the southern Hawaiian Islands (hereafterreferred to as Hawaiian waters)were studiedintensively by the PacificOcean BiologicalSurvey Program (POBSP) during 15 monthsin 1964 and 1965 (King 1970). Theseresearchers replicated a tracklineeach month and providedconsiderable information on the seasonaloccurrence and distributionof seabirds in these waters. The data were primarily qualitative,however, because the POBSP surveyswere not basedon a strip of defined width nor were raw counts corrected for bird movement relative to that of the ship(see Analyses). As a result,estimation of density(birds per unit area) was not possible. From 1984 to 1991, using a more rigoroussurvey protocol, we re- surveyedseabirds in the southeasternpart of the region (Figure1). In this paper we providenew informationon the occurrence,distribution, effect of oceanographicfactors, and behaviorof seabirdsin southeasternHawai- ian waters, includingdensity estimatesof abundant species. We also document the occurrenceof six speciesunrecorded or unconfirmed in thesewaters, the ParasiticJaeger (Stercorarius parasiticus), South Polar Skua (Catharacta maccormicki), Tahiti Petrel (Pterodroma rostrata), Herald Petrel (P. heraldica), Stejneger's Petrel (P.

Today we continue to be awestruck by this constantly changing archipelago. As the Nazca Plate moves and new islands are formed, evolution is illustrated up close and personal. Visiting the Galápagos archipelago is a dream for all naturalists. From Quito we will fly to the island of Baltra. We then will make our way to our home for the next eight days, the Samba, a spacious and luxuriously designed motor sailing yacht with wide open and shaded sun decks, a fully stocked bar, and a library. The abundant marine life that visits these waters year-round, the Marine Iguanas that rule the rocky coastlines, and of course a unique group of birds make it easy to understand why this trip is a must for birders and natural history buffs. Some of the Galápagos specials that we hope to find on this trip include Galapagos Penguin, Waved Albatross, Galapagos Shearwater, Wedge-rumped and Elliot’s Storm Petrels, Magnificent Frigatebird, Nazca, Red-footed, and Blue-footed Boobies, Lava Heron, Galapagos Hawk, Lava Gull, Galapagos Martin, Galapagos Flycatcher, Vermilion Flycatcher, Galapagos, Floreana, San Cristobal, and Espanola Mockingbirds, Vegetarian Finch, Woodpecker Finch, Common Cactus Finch, Green Warbler-Finch, Large and Small Tree Finches, Small and Medium Ground Finches, and Mangrove Finch. -
Systematic List of the Birds
59.82(66.53) Article III.-THE MARINE ORNITHOLOGY OF THE CAPE VERDE ISLANDS, WITH A LIST OF ALL THE BIRDS OF THE ARCHIPELAGO BY ROBERT CUSHMAN MURPHY CONTENTS PAGE. INTRODUCTION........................................................... 211 HISTORICAL SKETCH OF CAPE VERDE ORNITHOLOGY .............. .......... 212 THE VISITS OF CORREIA AND THE AUTHOR.................................. 213 THE GEOGRAPHIC ENVIRONMENT....................... 216 OCEANOGRAPHY AND CLIMATE............................................ 221 GEOGRAPHIC RELATIONSHIPS OF THE BIRDS ............................... 226 BIBLIOGRAPHY......................................................... 232 SYSTEMATIC LIST OF THE BIRDS............................................ 233 INTRODUCTION The present paper is an indirect result of a brief visit which the writer made to the Cape Verde Islands in September 1912. It is more immediately linked, however, with a collecting trip undertaken during part of the spring and summer of 1922 by Mr. Jos6 Gongalves Correia, of New Bedford, Mass., whose specimens, numbering some three hundred skins of twenty species, have all been received by The American Museum of Natural History. As Correia's predominant object was to acquire adequate series of water birds, the terrestrial species of the Cape Verdes are but scantily represented in his collection, which is supplemented, to a certain extent, by a small number of specimens obtained by the writer in 1912. Notwithstanding the relatively limited material available for study, it has been thought advisable to include within this paper a systematic list of all the birds known from the Cape Verde Islands. The latest faunal contribution is that of Salvadori (1899). Not only have addi- tions to the avifauna been made since that date, but also forms new to science, including several endemic races, have been described. More- over, numerous nomenclatural changes made necessary because of the researches of Hartert ('V6gel der palaarktischen Fauna,' 1910-22) and other workers increase the need for a new list.
