BARC SUBMISSION Cory's Shearwater Calonectris Borealis
BARC SUBMISSION Cory’s Shearwater Calonectris borealis – Bremer Canyon ‘hotspot’, Western Australia, 5th January 2020 Machi Yoshida (prepared by Daniel Mantle & Plaxy Barratt) Submission note: we believe this sighting constitutes the 3rd time that one or more Cory’s Shearwater have been sighted in Australia (after a bird seen off Bremer Bay on the 19th January 2019 and up to four birds off Denmark, Western Australia six days prior to this record). Taxonomic notes: Cory’s Shearwater Calonectris borealis is a relatively recent split from Scopoli’s Shearwater Calonectris diomedea as accepted by the IOC (version 9.2; following Robb & Mullarney 2008, Howell 2012, and Sangster et al. 2012) and the HBW-Birdlife list of birds (version 3.0). However, other taxonomies such as Clements (2019) still consider these two taxa as subspecies (C. d. borealis and C. d. diomedea, respectively). All three of these major taxonomies accept Cape Verde Shearwater Calonectris edwardsii as a distinct species. Circumstances of sighting: a single Cory’s Shearwater was observed and photographed by Machi Yoshida at the Orca ‘hotspot’ at the head of the Bremer Canyon (near the shelf edge), Western Australia on the 5th January, 2020. This sighting was considerably more distant than the birds seen off Denmark six days previously by Machi and Billy Thom. Description (from photo): • A large shearwater with a thick, yellow bill, pale whitish underparts and dull beige to brown upperparts. • The yellow bill is notably robust, bright yellow, and with a darker tip (the fine detail is not apparent, but presumed to be a dark subterminal band rather than full dark tip). -

The Taxonomy of the Procellariiformes Has Been Proposed from Various Approaches
山 階 鳥 研 報(J. Yamashina Inst. Ornithol.),22:114-23,1990 Genetic Divergence and Relationships in Fifteen Species of Procellariiformes Nagahisa Kuroda*, Ryozo Kakizawa* and Masayoshi Watada** Abstract The genetic analysis of 23 protein loci in 15 species of Procellariiformes was made The genetic distancesbetween the specieswas calculatedand a dendrogram was formulated of the group. The separation of Hydrobatidae from all other taxa including Diomedeidae agrees with other precedent works. The resultsof the present study support the basic Procellariidclassification system. However, two points stillneed further study. The firstpoint is that Fulmarus diverged earlier from the Procellariidsthan did the Diomedeidae. The second point is the position of Puffinuspacificus which appears more closely related to the Pterodroma petrels than to other Puffinus species. These points are discussed. Introduction The taxonomy of the Procellariiformes has been proposed from various approaches. The earliest study by Forbes (1882) was made by appendicular myology. Godman (1906) and Loomis (1918) studied this group from a morphological point of view. The taxonomy of the Procellariiformes by functional osteology and appendicular myology was studied by Kuroda (1954, 1983) and Klemm (1969), The results of the various studies agreed in proposing four families of Procellariiformes: Diomedeidae, Procellariidae, Hydrobatidae, and Pelecanoididae. They also pointed out that the Procellariidae was a heterogenous group among them. Timmermann (1958) found the parallel evolution of mallophaga and their hosts in Procellariiformes. Recently, electrophoretical studies have been made on the Procellariiformes. Harper (1978) found different patterns of the electromorph among the families. Bar- rowclough et al. (1981) studied genetic differentiation among 12 species of Procellari- iformes at 16 loci, and discussed the genetic distances among the taxa but with no consideration of their phylogenetic relationships. -
FEEDING ECOLOGY of the CAPE VERDEAN SHEARWATER (Calonectris Edwardsii) POPULATION of RASO ISLET, CAPE VERDE (P1-B-11)
2nd World Seabird Conference “Seabirds: Global Ocean Sentinels” 26-30 October 2015 Cape Town, South Africa FEEDING ECOLOGY OF THE CAPE VERDEAN SHEARWATER (Calonectris edwardsii) POPULATION OF RASO ISLET, CAPE VERDE (P1-B-11) Isabel Rodrigues1,3; Nuno Oliveira 2 Rui Freitas 3 Tommy Melo1 Pedro Geraldes 2 1Biosfera I, Cabo Verde, www.biosfera1.com; 2SPEA, Portugal, www.spea.pt, 3 Universidade de Cabo Verde, www.unicv.edu.cv Raso Islet with only 5.76 km2, is an area of great importance to Cape Verdean Shearwaters as we find one of the largest colonies of the species there. The great biological value of this islet is even more remarkable for hosting very large populations of other species, such as the Brown Booby, Red-billed Tropicalbird and even the endemic Raso Lark, among others. Along with Branco Islet, also included in the Nature Reserve, both populations constitute about 75% of the nesting population of the Cape Verde islands (Fig. 1). The Cape Verde Shearwater (Procellariiformes, Procellariidae) (Fig. 2) is an endemic species of Cape Verde and has recently been separated from Calonectris diomedea species, due to their morphological and genetic differences, and pelagic habits; feeding mostly on the open sea (Hazevoet 1995). METHODOLOGY RESULTS The samples were collected between 14 October and 12 November, in two In total, 80 regurgitations from juvenile Cape Verde Shearwaters were collected; consecutive years, 2012 and 2013. We randomly obtained 80 samples of juvenile including 50 individuals sampled in 2012, and 30 individuals in 2013. regurgitation. Each juvenile was sampled only once. During or after handling, Based on knowledge of local fish populations and according to the current juveniles tend to regurgitate stomach contents without the need to resort to the description, the identified prey of Cape Verde shearwaters belonged to 5 species induced regurgitation method. -
Albatross Or Mōlī (Phoebastria Immutabilis) Black-Footed Albatross Or Ka’Upu (Phoebastria Nigripes) Short-Tailed Albatross (Phoebastria Albatrus)
Hawaiian Bird Conservation Action Plan Focal Species: Laysan Albatross or Mōlī (Phoebastria immutabilis) Black-footed Albatross or Ka’upu (Phoebastria nigripes) Short-tailed Albatross (Phoebastria albatrus) Synopsis: These three North Pacific albatrosses are demographically similar, share vast oceanic ranges, and face similar threats. Laysan and Black-footed Albatrosses nest primarily in the Northwestern Hawaiian Islands, while the Short-tailed Albatross nests mainly on islands near Japan but forages extensively in U.S. waters. The Short-tailed Albatross was once thought to be extinct but its population has been growing steadily since it was rediscovered in 1951 and now numbers over 3,000 birds. The Laysan is the most numerous albatross species in the world with a population over 1.5 million, but its trend has been hard to determine because of fluctuations in number of breeding pairs. The Black-footed Albatross is one-tenth as numerous as the Laysan and its trend also has been difficult to determine. Fisheries bycatch caused unsustainable mortality of adults in all three species but has been greatly reduced in the past 10-20 years. Climate change and sea level rise are perhaps the greatest long-term threat to Laysan and Black-footed Albatrosses because their largest colonies are on low-lying atolls. Protecting and creating colonies on higher islands and managing non-native predators and human conflicts may become keys to their survival.

Introduction Rat control at the Rdum tal-Madonna Special Protected Area (SPA) was carried out as part of BirdLife Malta’s ongoing project to protect the Yelkouan shearwater, Puffinus yelkouan (EU Life Project LIFE06/ NAT/ MT/ 000097, SPA Site and Sea Actions saving Puffinus yelkouan in Malta). These cliff-nesting birds are known to be at great risk from rat predation, with annual losses of eggs and chicks between 40 and 100%. Around one-third of Malta’s 1500 breeding pairs of P. yelkouan nest at this site, making it an obvious focal point for conservation efforts (references in EU Project Proposal). The relatively small size of the SPA (75.3ha), and that it is surrounded by the ocean on three sides, make it a good site for rat control. -

First two cases of melanism in Cory’s Shearwater Calonectris diomedea. Marine Ornithology 33: 19-22. Although aberrant colourations occur in a great variety of animal species, their frequency of occurrence is low. Here, we report the first two observations of melanistic Cory’s Shearwaters Calonectris diomedea, in the Azores archipelago and on the Canary Islands. Because dark plumages may be associated with subordinate status within petrel flocks and with increased conspicuousness, melanistic individuals would have increased difficulties in obtaining food compared with their normally coloured conspecifics. This phenomenon might explain why melanism seems to occur less frequently than other aberrant colour patterns in this group. Key words: Melanism, Cory’s Shearwater, Calonectris diomedea, Procellariiformes INTRODUCTION individuals were found in 2003. The first individual was found near a pier at San Andrés on 30 October. The second observation Aberrant colourations have a low frequency of occurrence in occurred in a street of Horta on 21 November. -
Status and Occurrence of Manx Shearwater (Puffinus Puffinus) in British Columbia
Status and Occurrence of Manx Shearwater (Puffinus puffinus) in British Columbia. By Rick Toochin and Louis Haviland. Introduction and Distribution The Manx Shearwater (Puffinus puffinus) is a small species of shearwater found year round along both sides of the North Atlantic Ocean (Onley and Scofield 2007). This species has breeding colonies in Iceland, France, Faeroe Island, Ireland, Scotland, England, Channel Islands, Azores Islands, Madeira Island, and the Canary Islands (Onley and Scofield 2007). In eastern North America, the Manx Shearwater breeds in Newfoundland and is found in the Gulf of St. Lawrence to the Gulf of Maine (Lee and Haney 1996). Some of these birds winter in the North Atlantic Ocean off North America from the Carolinas to Florida, but most birds are trans- equatorial migrants from July to March wintering in the South Atlantic Ocean off Brazil to Argentina and spread across the South Atlantic to South Africa (Lee and Haney 1996, Onley and Scofield 2007). The Manx Shearwater has been undergoing a somewhat mysterious range expansion over the past few decades with more and more birds turning up in the North Pacific Ocean (Roberson 1996, Mlodinow 2004). Though breeding is suspected it has yet to be proven (Mlodinow 2004). One bird was tape recorded at night in a nesting burrow on Triangle Island by Dr. Ian Jones in the summer of 1994 (Mlodinow 2004). The bird was never actually seen and the bird’s identity was left unidentified for many years (P. Jones Pers. Comm.). Another possible breeding record comes from Alaska on Middleton Island on May 12, 2005, when 2 birds were seen together possibly prospecting for a nest site (Gibson et al. -
