Jaimie Cleeland (Institute for Marine and Antarctic Studies, University of Tasmania, Battery Point, Tasmania, Australia) and colleagues have published open access in the journal Scientific Reports on influence of introduced European Rabbits Oryctolagus cuniculus (now eradicated) and extreme weather patterns on the breeding albatrosses of Australia’s sub-Antarctic Macquarie Island.

The paper’s abstract follows:

“Invasive species present a major conservation threat globally and nowhere are their affects more pronounced than in island ecosystems.  Determining how native island populations respond demographically to invasive species can provide information to mitigate the negative effects of invasive species.  Using 20 years of mark-recapture data from three sympatric species of albatrosses (black-browed Thalassarche melanophris, grey-headed T. chrysostoma, and light-mantled albatrosses Phoebetria palpebrata), we quantified the influence of invasive European rabbits Oryctolagus cuniculus and extreme weather patterns on breeding probability and success.  Temporal variability in rabbit density explained 33–76% of the variability in breeding probability for all three species, with severe decreases in breeding probability observed after a lag period following highest rabbit numbers.  For black-browed albatrosses, the combination of extreme rainfall and high rabbit density explained 33% of total trait variability and dramatically reduced breeding success.  We showed that invasive rabbits and extreme weather events reduce reproductive output in albatrosses and that eliminating rabbits had a positive effect on albatross reproduction.  This illustrates how active animal management at a local breeding site can result in positive population outcomes even for wide ranging animals like albatrosses where influencing vital rates during their at-sea migrations is more challenging.”

“Albatrosses face multiple threats both on land and out at sea.  World Albatross Day represents an excellent opportunity to draw attention to the issues we must address to protect these extraordinary birds, as well as the opportunities and challenges associated with each of these threats.”

“Albatrosses already face so many threats at sea.  On some of the islands they breed on, they face existential threats from introduced predators as well, so the populations are getting squeezed from both land and sea.  World Albatross Day is a great opportunity to highlight not only the threats faced by these normally long-lived birds, but also some of the measures that can be taken to reduce the risks to them.  Without actions to reduce fishing mortality and introduced predators on their breeding islands, we face the sad but very real possibility of a world without albatrosses.”

“Having a World Albatross Day is a great idea.  I have dedicated a lifetime to the conservation of albatrosses and petrels, so having a World Albatross Day, as recognition of the global importance of those magnificent birds and the threats they face, is important in increasing global awareness of the importance of actions to prevent their extinction.”

“Ter um Dia do Albatroz é uma ótima ideia.  I tenho dedicado todo uma vida para a conservação de albatrozes e petreis, e ter um Dia do Albatroz, como um reconhecimento da importância global para essas aves magníficas e das ameaças que elas enfrentam, é crucial para aumentar a consciência global sobre a importância das ações para prevenir sua extinção

COVID-19 gets in the way of the World Albatross Day Banner Challenge at New Zealand’s Pukekura/Taiaroa Head

WAD Royal Albatross Centre 

A pair of Northern Royal Albatrosses on their nest on Pukekura/Taiaroa Head mark World Albatross Day, 19 June 2020

As part of its efforts to raise awareness of this year’s inaugural World Albatross Day on 19 June, ACAP Latest News contacted New Zealand’s Department of Conservation (DOC) which manages the Northern Royal Albatross colony on South Island’s Pukekura/Taiaroa Head with a request to join in the ‘WAD2020 Banner Challenge’ by making and photographing a suitably-worded banner in the field.

Pukekura/Taiaroa Head is the only locality on New Zealand’s mainland where albatrosses breed.  The carefully managed population of globally Endangered and nationally Naturally Uncommon Northern Royal Albatrosses Diomedea sanfordi can, under normal conditions, be viewed through large one-way glass windows in the visitor’s observatory run by the Royal Albatross Centre of the Otago Peninsula Trust.  However, movement restrictions and social-distancing requirements due to the COVID-19 pandemic have resulted in the centre being closed and has thus thwarted DOC’s plan to display and photograph a banner with a breeding albatross within the frame.

No problem for Kiwi ingenuity, as DOC Biodiversity Ranger, Sharyn Broni, who ordinarily works closely with the birds, regularly weighing the chicks and supplementary-feeding those deemed underweight, has come up with the first virtual WAD2020 banner.  In sending in her ‘banner’ Sharyn has commented:

“The Northern Royal Albatross has only four breeding sites in the entire world and they spend 85% of their time away from these sites circumnavigating the Southern Ocean searching for food.  Here at the mainland site of Pukekura/Taiaroa Head, New Zealand we manage a 250+ population but it is up to humanity to look after the world's oceans and fish stocks.”

A live-streaming ‘royalcam’ operated by DOC in conjunction with the USA’s Cornell Lab of Ornithology allows on-line visitors to view a breeding pair of albatrosses on a 24-hour basis in both COVID-19 and ‘normal’ times.

Effects of alien mammals on breeding of ACAP-listed Pink-footed Shearwaters

Pink footed Shearwater Peter Hodum s

Pablo García-Díaz (Landcare Research, Lincoln, New Zealand) and colleagues have published in the journal Environmental Conservation on effects of introduced European Rabbits on globally Vulnerable (and ACAP-listed) Pink-footed Shearwaters Ardenna creatopus.

The abstract follows:

“Alien species are a driver of biodiversity loss, with impacts of different aliens on native species varying considerably. Identifying the contributions of alien species to native species declines could help target management efforts.  Globally, seabirds breeding on islands have proven to be highly susceptible to alien species.  The breeding colonies of the  pink-footed shearwater (Ardenna creatopus) are threatened by the negative impacts of alien mammals. We combined breeding monitoring data with a hierarchical model to separate the effects of different alien mammal assemblages on the burrow occupancy and hatching success of the pink-footed shearwater in the Juan Fernández Archipelago, Chile.  We show that alien mammals affected the rates of burrow occupancy, but had little effect on hatching success.  Rabbits produced the highest negative impacts on burrow occupancy, whereas the effects of other alien mammals were more uncertain.  In addition, we found differences in burrow occupancy between islands regardless of their alien mammal assemblages.  Managing rabbits will improve the reproductive performance of this shearwater, but research is needed to clarify the mechanisms by which alien mammals affect the shearwaters and to explain why burrow occupancy varies between islands.”
