White-chinned Petrels can dive to 16 metres: relevance for mitigating longline bycatch

Dominic Rollinson and colleagues at the Percy FitzPatrick Institute of African Ornithology, University of Cape Town, South Africa have published in the journal Polar Biology on diving behaviour of the White-chinned Petrel Procellaria aequinoctialis.

The paper’s abstract follows:

“The white-chinned petrel (Procellaria aequinoctialis) is the seabird species most commonly killed by Southern Hemisphere longline fisheries.  Despite the importance of diving ability for mitigating longline bycatch, little is known of this species’ diving behaviour.  We obtained data from temperature–depth recorders from nine white-chinned petrels breeding on Marion Island, southwestern Indian Ocean, during the late incubation and chick-rearing period.  Maximum dive depth (16 m) was slightly deeper than the previous estimate (13 m), but varied considerably among individuals (range 2–16 m).  Males dived deeper than females, and birds feeding chicks dived deeper than incubating birds, but dive rate did not differ between the sexes.  Time of day had no significant effect on dive depth or rate.  Our findings will help to improve the design and performance of mitigation measures aimed at reducing seabird bycatch in longline fisheries, such as the calculation of minimum line sink rates and optimum aerial coverage of bird-scaring line.”

New Zealand’s Department of Conservation considers reports on albatross and petrel conservation efforts

The Conservation Services Programme (CSP) of New Zealand’s Department of Conservation works to reduce the impact of commercial fishing on protected species in New Zealand fisheries waters.  Direct commercial fishing impacts include species being caught, killed or injured in nets or on lines (bycatch).  Impacts may also be indirect through the modification of habitat or food availability.  The CSP monitors the effects of commercial fishing on protected species, studies species populations and looks at ways to limit bycatch (click here).

At regular meetings of the CSP’s Technical Working Group, reports on ongoing projects are considered, many of which deal with aspects of the biology and conservation of ACAP-listed albatrosses and petrels.  At its most recent meeting, held earlier this month, reports were considered for six species of albatrosses (Buller’s Thalassarche bulleri on The Snares, Campbell T. impavida and Grey-headed T. chrysostoma on Campbell Island, Gibson’s Diomedea antipodensis gibsoni on the Auckland Islands, Salvin’s T. salvini at sea and Southern Royal D. epomophora at the Aucklands).

Reports and presentations were also given on the Flesh-footed Shearwater Puffinus creatopus, on sea trials of the Kellian Line Setter and on characterising bottom longline operations in relation to risk factors for seabird capture.

Fluent in English and Spanish? American NGO seeks a Seabird Programme Director

"The American Bird Conservancy (ABC) is the only conservation group whose sole mission is to conserve native wild birds and their habitats throughout the Americas.  The ABC accomplishes its mission through direct action and by engaging the people, groups, resources, and strategies needed to succeed.  It undertakes the full spectrum of bird conservation issues using advocacy and habitat conservation strategies.

ABC's Seabird Conservation Programme advances the organization's mission by:

1. developing solutions to threats facing the oceanic birds of the Americas;

2. informing and educating policy-makers and resource managers about seabird conservation needs and solutions; and

3. influencing government agencies and multilateral institutions regarding policy, resource allocation, and international conventions that affect seabirds."

"The ABC is seeking a dynamic conservationist with the drive and entrepreneurial spirit to develop programmes and advance policies that will make a difference for seabirds.  The Seabird Program Director is responsible for implementing an ambitious strategic plan for seabird conservation in the Americas; developing and implementing on-the-ground conservation projects to counter threats faced by the hemisphere's imperilled seabirds; developing capacity in partner organizations abroad; reaching out to US and foreign governments and helping to ensure adequate funding for the programme."

ACAP Breeding Site No. 72: Nakodojima Island, where Black-footed and now Short-tailed Albatrosses breed

Nakodojima Island (1.37 km²) is located in the middle of the Mukojima Island Group of Japan’s Ogasawara (Bonin) Islands.  It lies five kilometres south of Mukojima where the Short-tailed Albatross Phoebastria albatrus restoration project is situated.  It takes three hours by boat to reach Nakodojima, travelling 50 km north from inhabited Chichijima Island.  In the early 1900s, colonists started to farm and ranch on Nakodojima but since World War II the island has been uninhabited.

Black-footed Albatrosses P. nigripes Albatrosses breed on Nakodojima, with 967 pairs recorded in 2006 according to the ACAP Data Portal.  On 7 May this year a Short-tailed Albatross P. albatrus chick close to fledging was found on the island.  The bird was colour banded and a feather sample taken for DNA analysis to aid in its positive identification (click here).

Around 30 years ago grazing by feral Domestic Goats Capra aegagrus hircus had seriously damaged the forest on the island resulting in serious erosion.  The Tokyo Metropolitan Government (TMG) successfully undertook a feral goat eradication programme that removed 417 animals on Nakodojima from 1997 to 1999, and has managed a forest restoration programme since then. The Black Rat Rattus rattus is now the last remaining introduced mammal on the island

Since 1978 the TMG has monitored the status of Black-footed Albatrosses breeding within the Mukojima Island Group.  In the 2004 breeding season the Institute of Boninology (NPO) joined the monitoring programme and started plastic colour banding birds for population analysis.  Following eradication of feral goats throughout the Mukojima Island Group the numbers of Black footed Albatrosses have increased gradually in all colonies, and their breeding area is expanding.  In May 2014 1040 Black footed and 12 Laysan P. immutabilis Albatross chicks were banded in the Mukojima Island Group.

The Ogasawara Islands were designated as a World Heritage Natural Site in June 2011, with Nakodojima Island being treated as its most restricted area.

A management plan and an action plan for protection and management of property are being implemented by the Ministry of the Environment (Ogasawara National Park, Ogasawara Archipelago National Wildlife Protection Area), Forestry Agency (Ogasawara Islands Forest Ecosystem Reserve), Tokyo Metropolitan Government and Ogasawara Village with the local community’s participation facilitated through a Regional Liaison Committee.

On Nakodojima commercial developments and usage are prohibited and recreational activities are not allowed.  Scientists and forest restoration programme managers visit under permit.  In order to avoid disturbance to the albatrosses, the forest restoration programme is limited to outside the albatross breeding season.

To improve conservation measures for the Short-tailed Albatross chick found on Nakodojima 2014, a local conference on albatrosses that was organized by local government agencies, NPO, fisheries, tourist group and scientists in 2008, will re-start to discuss implementing a ban of entering the STAL’s breeding site in the coming season.

Heinroth’s Shearwater more than one species?

Writing in the New Zealand journal Notornis Peter Harrison reports on the little-known Heinroth’s Shearwater Puffinus heinrothi of the Solomn Islands.

The paper’s abstract follows:

“This paper reports recent at-sea sightings of the little-known Heinroth’s shearwater (Puffinus heinrothi) within the Solomon Islands.  Feeding habits are described and compared to those of black noddy (Anous minutus).  Observations suggest that Heinroth’s shearwater occurs in dark, intermediate and pale forms, and may be better considered as a polymorphic species.”
