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.

  • Foraging Behavior and Diet of Streaked Shearwaters Calonectris Leucomelas Rearing Chicks on Mikura Island

Birds spent 76–96% of of Japan 2012 their time at sea flying, 4–24% for landing on the water, and made a few (0.5–17.0 per day) shallow (<6 m) dives. Birds made many short (<2 days) and some long (4–10 days) trips. During short trips, birds stayed in the warmer Kuroshio and Kuroshio-Oyashio mixed regions, and fed on Japanese Anchovy Engraulis japonicus, Common Squid Todarodes pacificus and Flying Fish Cypselurus hiraii. During long trips, birds stayed in the colder Oyashio region and fed on anchovy and Pacific Saury Cololabis saira. Birds made more dives during short trips than they did during long trips. Streaked Shearwaters breeding on the island in low—productive Kuroshio water, therefore, adopted dual foraging strategies, and changed their diet and dive frequencies in relation to water masses.

  • Breeding Population of Streaked Shearwaters (Calonectris Leucomelas) and the Effect of Norway Rat (Rattus Norvegicus) Predation on Sasudo Island
    山 階 鳥 研 報(J. Yamashina Inst. Ornithol.), 33:142-147,2002 Breeding Population of Streaked Shearwaters (Calonectris leucomelas) and the Effect of Norway Rat (Rattus norvegicus) Predation on Sasudo Island Kyung-Gyu Lee* and Jeong-Chil Yoo* Abstract. To estimate the breeding population of Streaked Shearwaters (Calonectris leucomelas) on Sasudo Island, Jejudo, Korea, quadrat surveys were conducted during the hatching period in 1998, the early rearing period in 1999 and the early incubation period in 2000. In 2000, burrow density was 0.15/m2±0.02 (mean±SE). Burrow density was high in the abandoned field, rocky area and take off site of the birds in the island, where 71.3% of 595 burrows were occupied. The breeding population was estimated to be 7,486 ±3,000 pairs (mean±SE). Only 36.4% and 19.8% of burrows were occupied in 1998 (n=353) and 1999 (n=140), respectively. Burrow occupancy seemed to decrease through the breeding stages. Breeding failures were recorded in 31 out of 54 burrows (57.4%) in 7-29 August 1999. Predation by Norway Rats (Rattus norvegicus) was possibly the cause of mortality of eggs or chicks in 26 of these 31 unsuccessful burrows. Norway Rat predation may be the main factor affecting the breeding success of Streaked Shearwaters on the island. Key words: Breeding population, Burrow density.

  • Paleoceanographic Changes in the Late Pliocene Promoted Rapid
    Paleoceanographic changes in the late Pliocene promoted rapid diversification in pelagic seabirds Joan Ferrer Obiol1, Helen James2, R. Chesser2, Vincent Bretagnolle3, Jacob Gonzales-Solis1, Julio Rozas1, Andreanna Welch4, and Marta Riutort1 1Universitat de Barcelona Facultat de Biologia 2Smithsonian Institution 3Centre d’Etudes´ Biologiques de Chiz´e,CNRS & La Rochelle Universit´e 4Durham University Department of Biosciences October 12, 2020 Abstract In marine environments, paleoceanographic changes can act as drivers of diversification and speciation, even in highly mobile marine organisms. Shearwaters are a group of pelagic seabirds with a well-resolved phylogeny that are globally distributed and show periods of both slow and rapid diversification. Using reduced representation sequencing data, we explored the role of paleoceanographic changes on diversification and speciation in these highly mobile pelagic seabirds. We performed molecular dating, applying a multispecies coalescent approach (MSC) to account for the high levels of incomplete lineage sorting (ILS). We identified a major effect of the Pliocene marine megafauna extinction, followed by a period of high dispersal and rapid speciation. Biogeographic analyses showed that dispersal appears to be favoured by surface ocean currents, and we found that founder and vicariant events are the main processes of diversification. Body mass appears to be a key phenotypic trait potentially under selection during shearwater diversification, and it shows significant associations with life strategies and local conditions. We also found incongruences between the current taxonomy and patterns of genomic divergence, suggesting revisions to alpha taxonomy. Globally, our findings extend our understanding on the drivers of speciation and dispersal of highly mobile pelagic seabirds and shed new light on the important role of paleoceanographic events.

Here, we examined the foraging area of streaked shearwaters Calonectris leucomelas, breeding at Sangan (SA) and Mikura Islands (MK), Japan, from spring to summer during pre-laying and incubation periods. Those colonies are located at the north and south of the Northwestern Pacific’s Kuroshio-Oyashio transition area where high seasonal temperature changes are observed, and where, consequently, birds may show comparable responses to such changes. Our results showed that streaked shearwaters from both colonies shifted their foraging areas northwards as the season progressed. The seasonal shift of foraging areas appeared to coincide with the movement pat- tern of pelagic fishes that migrate northward in association with the increase in water temperature.
