Ewan Wakefield (Institute of Biodiversity, University of Glasgow, United Kingdom) and colleagues have published a grant report in the Seabird Group Newsletter (and on the grants page on the group’s website) on a study of the numbers and at-sea movements of globally Near Threatened Sooty Shearwaters Ardenna grisea at the Falkland Islands/Islas Malvinas*.

The authors report an estimate of “well in excess of 100,000 pairs” on Kidney Island, a population thought to be increasing in numbers. Birds tracked at sea from Kidney Island showed “the vast majority” foraged south of the island group in a region partly within an Argentinian Marine Protected Area (MPA).

At an estimated 67 years of age, Wisdom the globally Near Threatened Laysan Albatross Phoebastria immutabilis, the world’s oldest known breeding bird, hatched her latest egg (click here) on 6 February this year. Wisdom and her mate Akeakamai of 12 years breed on Midway Atoll in the North Pacific; both are colour-banded to aid in identification.

Wisdom has been breeding on Midway Atoll since at least 1956, when she was first banded by the late Chandler Robbins.

She has successfully raised an estimated 30-36 albatross chicks over the course of her life to date.

Vincent Bourret (CEFE, CNRS-Université de Montpellier, France) and colleagues have published open access in the journal Conservation Letters on a novel procedure to reduce the effects of disease on globally Endangered Indian Yellow-nosed Albatrosses Thalassarche carteri on France’s Amsterdam Island.

The paper’s abstract follows:

“Global change is contributing to unprecedented expansions of infectious diseases in wildlife. Recurrent avian cholera outbreaks are causing dramatic chick mortality and population decline in endangered albatross colonies on Amsterdam Island, a critical seabird breeding ground in the Southern Indian Ocean.We manufactured a killed vaccine using a Pasteurella multocida strain isolated from a dead albatross in the field. We used this same bacterial strain to establish a serological assay allowing the monitoring of antibody levels following bird vaccination. Using this vaccine on chicks 2 weeks posthatching caused 100% seroconversion and reduced the death risk by a factor exceeding 2.5, raising fledging probability from 14% to 46%. These results suggest that using a specifically tailored vaccine could be a key tool to effectively protect endangered seabirds from disease outbreaks threatening them with extinction.”

In February 2017 15 globally Near Threatened Black-footed Albatross Phoebastria nigripes chicks were translocated by air from the Midway Atoll National Wildlife Reserve for hand rearing in the James Campbell National Wildlife Refuge on the Hawaiian island of Oahu. Fourteen successfully fledged; the 15th chick died shortly before fledging. The aim is to create a new breeding colony less vulnerable to the effects of sea level rise and extreme weather events (click here).

This year 23 Black-foot chicks were collected from Midway and Tern Island within the Papahānaumokuākea Marine National Monument and brought back to the James Campbell National Wildlife Refuge on a five-day sea voyage. As in the previous year the chicks were taken from nests near the water’s edge and so deemed to be in danger of being washed away by storms. The chicks have now now settled into their home in the refuge and will be placed outside tomorrow, following an indoor quarantine period when they were inspected by a veterinarian.

“No Net Loss is an initiative of Pacific Rim Conservation, a non-profit conservation organization based in Hawaii that focuses on island bird restoration. We have partnered with landowners, non-profit organizations and government agencies to create a series of “mainland islands” (fenced, predator-free sites on inhabited islands) as well as completely predator-free islands that will serve as “Arks” for island species in Hawaii and the Tropical Pacific. We help to restore bird species to these mainland islands by using translocation or social attraction.”
