Mark Tasker, who resides in Scotland, is a retired Head of Marine Advice at the UK’s Joint Nature Conservation Committee (JNCC) and a long-time veteran of the international Agreement on the Conservation of Albatrosses and Petrels (ACAP).  He has served as head or as a member of the UK Delegation to all but one ACAP meeting since the Agreement's first in 2004, and to negotiation meetings prior to that, is a past Chair and Vice Chair of ACAP’s Advisory Committee and is currently Convenor of the ACAP Taxonomy Working Group.  Mark has worked with albatrosses primarily in the Falkland Islands/Islas Malvinas* and on South Georgia/Islas Georgias del Sur*, and he managed the work of the JNCC’s ACAP Coordinator for the South Atlantic. The Coordinator from 2008-2013 was Anton Wolfaardt, now the Manager of the Mouse-Free Marion Project that aims to rid the island of its albatross-killing House Mice during the austral winter of 2023.  In 2011/12 Mark and Anton worked together trapping rats on South Georgia/ Islas Georgias del Sur* - now thankfully rodent free following an eradication campaign by “Team Rat”.

Mark writes to ACAP Latest News: “Albatrosses are one of the pinnacles of evolution in harnessing the winds to search much of the world’s oceans for food.  Sadly, human activities are putting them at risk of extinction.  Among these (often accidental) activities is the introduction of non-native organisms; removing these from islands is among the most important things we can do to advance the conservation of these magnificent seabirds.”  With his experience and passion for procellariiform seabirds and the restoration of their island habitats by removing introduced predators, it is no great surprise, but nevertheless most welcome news, that he is now supporting the attempt to rid South Africa’s sub-Antarctic Marion Island of its alien predators.  Mark’s generous sponsorship will allow the project to treat 25 hectares of the 29 000-ha island come 2023.  So far 738 individuals have sponsored 1967 hectares, which is only 6.56% of the island’s total area - so there is still a long way to go to make the project a reality.  Mark D. Anderson, CEO of BirdLife South Africa, thanked Mark for his generous sponsorship, and the many others who have already contributed, saying that "these contributions will help us secure a significant conservation legacy for Marion Island's seabirds."

Sponsor a hectare planning

The Sponsor a Hectare scheme was first proposed by ACAP’s Information Officer, inspired by the crowd-funding success of the Million Dollar Mouse project to eradicate mice on New Zealand’s Antipodes Island.  His own sponsorship towards a Mouse-Free Marion does not come close to matching Mark’s but watch this space!

ProDelphinus Peru produces Spanish guides for the safe handling and release of marine megafauna, including seabirds

ProDelphinus infographic

Infographic in Spanish by ProDelphinus Peru describes the safe handling and release of bycaught seabirds

The environmental NGO ProDelphinus Peru has produced six videos for Spanish speakers that describe procedures for the safe handling and releasing of marine megafauna that get incidentally caught by fisheries in the south-east Pacific Ocean.  The animal groups covered in six separate videos are marine mammals, fish (sharks and rays), turtles and seabirds.  The video for seabirds is intended to decrease the post-release mortality after a bycatch event.

Este video fue preparado como una guia de buenas practicas para la manipulacion y liberacion de fauna marina de pesqueria incidental. El video sobre aves marinas busca aumentar la sobrevivencia de las aves luego de la captura y posterior liberacion. Este y otros materiales similares fueron preparados por ProDelphinus Peru, con el apoyo de National Fish and Wildlife Foundation, para promover pesquerias sostenibles en el Pacifico Oriental.

Joanna Alfaro of ProDelphinus Peru writes to ACAP Latest News:

“I am also attaching the link to a Guide for Assessing Small-scale Fisheries. This guide compiles information from our own experience in Peru, from assessing these fisheries, to identifying potential solutions.  We hope it may be useful for Spanish-speaking countries.  I am also sharing a Guide for Best Practices in Sustainable Small-scale Fisheries that includes information about improving commercialization of fish, reducing pollution, reporting bycatch, technologies to improve fisheries, and COVID health measures for safe fishing.”

ProDelphinus Peru has produced the various materials with the support of the National Fish and Wildlife Foundation.

Down we go. Christmas Shearwaters from Kure Atoll can dive to 24 metres

 Christmas Shearwater FWS

Ilana Nimz (Hawai‘i Pacific University, Waimanalo, Hawaii, USA) and colleagues have published open access in the journal Marine Ornithology on diving behaviour in Christmas Shearwaters Puffinus nativitatis.

The paper’s abstract follows:

“The Christmas Shearwater Puffinus nativitatis is an aquatic, tropical shearwater. While individuals of this species are known to forage by pursuit plunging and diving, there are no published reports quantifying their sub-surface foraging behavior. We obtained diving information from eight chick-rearing Christmas Shearwaters on Kure Atoll during June-August 2017. Over the 33 days during which instruments were deployed, 1521 dives were recorded. Individual deployments lasted three to eight days and were independent of the maximum depths recorded. Individual maximum depths were 10.7-24.1 m, averaging 15.4 m. While the deepest and longest recorded dive reached 24.1 m and lasted 31 s, the majority of dives were < 3.0 m deep (64%) and lasted ≤ 3.0 s (53%). Overall, deeper dives were longer. Almost all diving occurred during daylight, with peak diving activity (13%) occurring between 17h00 and 18h00 (dusk). Genetic metabarcoding identified digested prey items from regurgitations, distinguishing 11 species of fish and squid. This study highlights the way in which this species of concern uses the epipelagic foraging habitat within the Papahānaumokuākea Marine National Monument.”

Do fence me in. Translocating threatened Newell’s Shearwaters and Hawaiian Petrels

Newells Shearewater Lindsay Young

Lindsay Young (Pacific Rim Conservation, Honolulu, Hawaii, USA) and colleagues have published on hand rearing translocated chicks of the Critically Endangered Newell’s Shearwater Puffinus newelli and Endangered Hawaiian Petrel Pterodroma sandwichensis within a predator-proof fence on the Hawaiian island of Kauai as part of the Nihoku Ecosystem Restoration Project.

An extract from the chapter’s Introduction follows:

“The Critically Endangered Newell’s shearwater (Puffinus newelli) and the Endangered Hawaiian petrel (Pterodroma sandwichensis) are Hawaii’s only endemic seabirds.  Both species are rapidly declining due to collisions with power lines, light attraction, predation by invasive feral mammals and introduced Barn owls and habitat degradation by feral ungulates and invasive plants. Given the challenges in protecting nesting birds in their rugged, montane habitat, it has long been desirable to create protected populations of both species in more accessible locations. Translocation has been part of recovery planning since 1983 and translocation to predator exclusion fences was ranked as the highest priority action in the interagency five year Action Plan for Newell’s shearwater and Hawaiian petrel.”

The publication concludes:

The translocation aspect (removal of chicks from natal burrows and hand rearing until fledging) was highly successful, with fledging rates of 100% for Newell’s shearwater (N=67/67) and 98% for Hawaiian petrel (N=87/90).  It is still too early to determine ultimate success, which would entail recruitment of breeding individuals to the release site.”
