Felipe, the Waved Albatross

A Critically Endangered Waved Albatross Phoebastria irrorata found by a villager within the Pantanos de Villa Wildlife Refuge in the district of Chorrillos on the coast of Peru near Lima on the 14th of last month was collected and taken into care in the Parque de las Leyendas (Legends Park Zoo) in Lima.  The bird, given the name “Felipe”, was X-rayed for injuries and checked for disease by veterinarians from the Escuela de Medicina Veterinaria (School of Veterinary Medicine), Universidad Ricardo Palma and found to be in good health after two weeks in captivity.   Following being banded by the environmental NGO Pro Delphinus the bird was transported by staff from the Servicio Nacional de Areas Protegidas por el Estado (Peruvian Service for Natural Protected Areas; SERNANP) and Servicio Nacional Forestal y de Fauna Silvestre (National Forest and Wildlife Service; SERFOR) to the coastal town of Ancon a few tens of kilometres north of Lima.  Felipe was then taken out to sea and released on 3 March, as depicted by video.

Felipe gets weighed

The Waved Albatross, along with the equally Critically Endangered Tristan Albatross Diomedea dabbenena, has been chosen as a “feature species” to support this year’s World Albatross Day on 19 June, with its theme of “Ensuring Albatross-friendly fisheries”.  Specially prepared posters and an infographic featuring both albatrosses are available for viewing and downloading on this website.  Versions have been produced in both English and Spanish.  Click here to view the ACAP Species Summary for the Waved Albatross.

Francesco Ventura (Departamento de Biologia Animal, Universidade de Lisboa, Portugal) and colleagues have published in the journal Polar Biology on chick mortality events in the Black-browed Albatross Thalassarche melanophris on New Island in the South Atlantic.

The paper’s abstract follows:

“In the context of environmental change, determining the causes underpinning unusual mortality events of vertebrate species is a crucial conservation goal. This is particularly true for polar and sub-polar colonial seabirds, often immunologically naïve to new and emerging diseases. Here, we investigate the patterns of black-browed albatross (Thalassarche melanophris) chick mortality events unrelated to predation recorded between the 2004/05 and 2019/2020 breeding seasons in four colonies across the species range in the Falklands. The prevalence of these mortality events was highly variable across years, causing the death of between 3 and 40% of all chicks in the studied plots. With few exceptions, mortality was patchily distributed. Using clustering methodologies, we identified the spatio-temporal mortality clusters based on the nest locations and chick death date. Using generalised linear models and generalised additive mixed-effects models we found that chicks nearer the first mortality event were predicted to die before those in more distant nests. The probability of death increased with age and was highest for chicks close to nests where a chick had died previously. Our findings, along with the symptoms consistently exhibited by most deceased chicks in the study, strongly suggest the prevalence of a widespread infectious disease, potentially with a common aetiology, both in areas with regular and with very rare human presence. Understanding the causes driving these disease-related mortality events, which seem different from the outbreaks documented in the literature, is a conservation priority for the Falklands black-browed albatross population, which comprises over 70% of the species global population.”

One of the species in the study: Black Petrel  at sea by Griselle Chock in gouache, from a photograph (see below) by Virginia Nicol 

Martin Beal (Marine and Environmental Sciences Centre, University of Lisbon, Portugal) and many co-authors from 16 countries have published open access in the journal Science Advances showing from at-sea tracks of 39 species of albatrosses and large petrels breeding  at 87 localities that their conservation is dependent on international action on the high seas.  The data used in the analysis came from BirdLife International’s Seabird Tracking Database that facilitates collaboration between researchers working on the conservation of seabirds.

The paper’s abstract follows:

“Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.”

Two Black-footed Albatrosses display  at Kaena Point (see text for details)

The Kaena Point Natural Area Reserve on the Hawaiian Island of Oahu is the site of breeding colonies of Laysan Albatrosses Phoebastria immutabilis (Near Threatened) and Wedge-tailed Shearwaters Ardenna pacifica, protected by a predator-proof fence.  As well as the breeding Laysans, the reserve has since at least 2006 been visited by Black-footed Albatrosses Phoebastria nigripes (Near Threatened), helped by the presence of decoys and a sound system; but as up to now breeding has not been recorded.

This seems likely to change as the non-profit organisation Pacific Rim Conservation has stated recently on its Facebook page: “The last two years have seen a huge increase in the number of Black-footed Albatross visiting Kaena Point.  Pictured … is V541 (male) who we banded in 2018, and his new companion, V949 (female) who we banded earlier this year. These two have been seen visiting the colony daily and doing their courtship dance.  While it is too late for them to breed in 2021, we are hopeful that this pair will nest next year and become the first ever Black-footed Albatross pair on Oahu.”

Meanwhile the last year’s cohort (of five) of Black-footed Albatross chicks relocated under permit from the Midway Atoll National Wildlife Refuge (taken from nests at risk of being washed away by storms) to the James Campbell National Wildlife Refuge on Oahu are out of in-door quarantine and doing well in their outside homes, according to Pacific Rim Conservation.  In the first four cohorts 86 out of 90 hand-reared chicks successfully fledged (click here).

So will it be James Campbell or Kaena Point that becomes the first-ever breeding site for Black-footed Albatrosses on Oahu – safe from predicted sea level rise?  Time will tell!
