A Northern Giant Petrel Macronectes giganteus (globally Least Concern) has been found 40 years after it was banded as a chick with number 131-40970 on 23 January 1981 by the Australian Antarctic Division at Mawson Point, Macquarie Island.  Forty years later, on 5 February 2021, the bird was recovered “at the end of its life” by a New Zealand Department of Conservation Biodiversity Ranger at Waikanae Beach, about 50 km north of Wellington, New Zealand, over 2200 km from its banding location.  According to the Australian Bird and Bat Banding Scheme (ABBBS) the recovery is the oldest Australian-banded Northern Giant Petrel on record.

“This band represents the longest time elapsed between banding and recovery recorded for this species and is one of the oldest birds ever recovered under the Scheme.  The maximum longevity record of an Australian-banded bird is held by a Short-tailed Shearwater [Ardenna tenuirostris] which was recovered 48 years and 3.8 months after banding.  The ABBBS holds 13 400 banding records for Northern Giant Petrels, of which 564 have been recovered.  The average time elapsed between banding and recovery is 8 years and 7.6 months.”

Black-foots from USA to Mexico: first international albatross translocation is underway

Guadaupe translocation

A long-term conservation project: “Reintroduction of Black-footed Albatrosses (Phoebastria nigripes) from Midway Atoll National Refuge, USA to Guadalupe Island Biosphere Reserve, Mexico” has been initiated by the United States Fish & Wildlife Service (USFWS) and Pacific Rim Conservation (PRC), together with Mexico’s Comisión Nacional de Áreas Naturales Protegidas (CONANP) and the Mexican environmental NGO Grupo de Ecología y Conservación de Islas (GECI).  The globally Near Threatened Black-footed Albatross has been reported  breeding in the past (one chick in 1998) on Isla Guadalupe, some 260 km off the west coast of Baja California.  Since 2000 GECI biologists have recorded sightings of individual Black-footed Albatrosses on the island and its islets and many in surrounding waters, but no breeding has been recorded.  Introduced feral cats are now being removed from the island, thus helping the island’s existing populations of Laysan Albatrosses P. immutabilis and other seabirds.  According to GECI's Federico Méndez Sánchez cat eradication is close to completion; good news for all the island's seabirds, including  reintroduced Black-footed Albatrosses.

The project has recently produced a media release, parts of which follow describing the translocation activities to date and its plans for the future:

“Reintroduction of the Black-footed Albatross is being carried out through the transfer of eggs and chicks from Midway Atoll National Wildlife Refuge to the Guadalupe Island Biosphere Reserve.  The techniques used in the project are based on the most up-to-date ethical and scientific standards developed and adapted by Pacific Rim Conservation during previous similar projects in the Hawaiian Islands. The Black-footed Albatross eggs will be cross-fostered into Laysan Albatross nests, and the chicks will be hand-raised.  To minimize any impacts to the source population on Midway, the eggs and chicks were collected from nests next to the ocean, where they were at risk of being washed away by high waves."

"The first 21 eggs were flown from Midway to Honolulu by the USFWS on 17 January 2021, and then to San Diego, California by PRC. Then, they were imported into Mexico on 18 January and flown to Guadalupe Island by PRC, GECI and CONANP staff.  The eggs were placed in foster nests of Laysan Albatrosses in which the natural egg was infertile.  In early February, 18 of the 21 eggs hatched, representing an 86% hatching success rate, similar to the rate in natural Laysan Albatross nests on Guadalupe and in other inter-island translocation projects in Hawaii by PRC.

On 18 February, nine Black-footed Albatross chicks were imported from Midway and arrived in Mexico and were successfully released on Guadalupe, where they will be raised by a team of biologists and veterinarians from PRC and GEC.  The 27 Black-footed Albatross chicks are expected to fledge from Guadalupe in June.  For the next couple of years (2022-2023), the binational team aims to move up to 42 eggs and 25 chicks per year in order to have at least 100 individuals to form the new breeding colony on Guadalupe."

"Because Black-footed Albatrosses are faithful to the place where they hatched or were raised from a young age it is expected that this generation of chicks will return to nest on Guadalupe when they are mature.  The reintroduction of Black-footed Albatrosses is a long-term project because albatrosses are long-lived; they will spend their first few years at sea continuously and are expected to begin returning to Guadalupe in three to five years and to begin nesting there in eight to nine years.”

David Hyrenbach (Hawai‘i Pacific University) and Michelle Hester (Oikonos Ecosystem Knowledge) study Wedge-tailed Shearwaters or 'Ua'u kani Ardenna pacifica; Least Concern) in the Freeman Seabird Preserve on the Hawaiian island of Oahu. They write of the most recent breeding season in the Hawaii Audubon Society journal ‘Elepaio:

“We report on the ongoing monitoring and restoration efforts of the Freeman Seabird Preserve by Hawaii Audubon Society and Hawai‘i Pacific University since 2009, share findings from the 2020 breeding season, and briefly discuss the plans for future monitoring, habitat restoration, and predator control at the site.  This year we documented 358 active nests.  This year’s nest count is the highest to date, surpassing the previous peak documented in 2019.”

Breeding performance in occupied ceramic nests for the second year since their establishment was similar to that of existing natural and roof tile nests in the preserve (80.0 % (8/10) in the ceramic nests and 72.7% (48/66) in the control nests).  Additional restoration and management efforts in 2021 will involve monitoring the colony and enhancing breeding habitat.

Getting the hang of it: Amsterdam and Wandering Albatrosses develop adult foraging capacities within two months of fledging

Adrien Pajot (Centre d'Etudes Biologiques de Chizé, Villiers‐en‐Bois, France) and colleagues have written in the Journal of Avian Biology on development of foraging activity in juvenile Amsterdam Diomedea amsterdamensis and Wandering D. exulans Albatrosses.

The paper’s abstract follows:

“The first year of life is a period of high mortality in animals. Reduced foraging capacities of naive individuals might be the primary cause of their mortality. These capacities are supposed to be progressively acquired during the first months of life. In this study, we investigate the ontogeny of flight capacities, by day and night, of first‐year individuals, and compare it with adults from two closely related species of great albatrosses: Amsterdam Diomedea amsterdamensis and wandering Diomedea exulans albatrosses which forage in different environmental conditions. We used 71 tracks of 71 juvenile birds and 141 of 116 incubating adults to compare both age categories. In order to explore the effect of moon light on night activity, we elaborated a new formula which improves the precision of the proxy of moon illumination. By day, we found that juveniles of both species reach some adult foraging capacities in less than two months. By night, albatrosses have reduced activity increasing during the first weeks at sea for juveniles and changing in accordance with moon illumination for both juveniles and adults. A peak of flight activity at dawn and dusk was apparent for both species. Interspecific comparison underlined that Amsterdam albatrosses were more active than wandering albatrosses, suggesting a difference in food and foraging strategy. Overall, we highlighted how life history traits, environmental conditions and time of the day affect the foraging activity of two related species of seabirds.”
