A review of wildlife census guidelines using drones or satellites published

ACAP Guidelines remotesensing Attard PaperFigure 1 from the paper shows examples of wildlife detected in satellite and unmanned aircraft system (UAS) imagery. (a) VHR satellites can be used to count individual animals provided that they meet key detection criteria: in an open habitat, of suitable size, and of contrasting colour to the background. For instance, African elephants are visible in open savannahs using 31 cm resolution WorldView-3 imagery [14]. (b) Indirect counts can be performed for species which are not directly detectable; for example, colony sizes of emperor penguins can be estimated from the colony area or the extent of guano staining using 10 m resolution Sentinel-2 satellite imagery [15]. (c) Spectral imagery collected by UAS is typically of higher resolution than that of satellite sensors, enabling counts of smaller animals, such as black-browed albatrosses, in open habitats [16]. (d) For species in closed-cover habitats, for instance, koalas in tree canopy (shown in yellow box), thermal cameras mounted on UAS can aid detection [17].

Marie R. G. Attard (British Antarctic Survey, Natural Environment Research Council, Cambridge, UK) and colleagues have published open access in the journal, Remote Sensing, Census Guidelines using drones or satellites. 

The paper, which was discussed at the 7th Meeting of the Albatross and Petrel Agreement’s Population and Conservation Status Working Group, provides an introduction for wildlife biologists and managers relatively new to the field on how to implement remote-sensing techniques (satellite and unoccupied aircraft systems) for counting large vertebrates on land, including marine predators that return to land to breed, haul out or roost, to encourage wider application of these technological solutions.

A link to the article is also available on the ACAP website via the Conservation Guidelines page

The abstract follows:

“Although many medium-to-large terrestrial vertebrates are still counted by ground or aerial surveys, remote-sensing technologies and image analysis have developed rapidly in recent decades, offering improved accuracy and repeatability, lower costs, speed, expanded spatial coverage and increased potential for public involvement. This review provides an introduction for wildlife biologists and managers relatively new to the field on how to implement remote-sensing techniques (satellite and unoccupied aircraft systems) for counting large vertebrates on land, including marine predators that return to land to breed, haul out or roost, to encourage wider application of these technological solutions. We outline the entire process, including the selection of the most appropriate technology, indicative costs, procedures for image acquisition and processing, observer training and annotation, automation, and citizen science campaigns. The review considers both the potential and the challenges associated with different approaches to remote surveys of vertebrates and outlines promising avenues for future research and method development.”

A ten-day-old Northern Royal Albatross chick succumbs to ingested plastic

A 10-day old Endangered Northern Royal Albatross Diomedea sanfordi chick has died while under care in the Wildlife Hospital in Dunedin after it swallowed soft plastic that had been regurgitated to it by its parent at Taiaroa Head/Pukekura, South Island, New Zealand.  The soft but tough plastic was discovered during necropsy to have caused an obstruction in the gastrointestinal tract, which ultimately led to starvation and organ failure.

Department of Conservation biodiversity ranger Sharyn Broni said it was the first death of its kind at the Taiaroa Head colony, but rangers had feared something like this could happen after other close calls in recent years.

“This heartbreaking incident is a reminder it's vital to dispose of plastic rubbish carefully.  People can also help by picking up litter they see on beaches, near waterways, or out on the ocean. Every piece you pick up could save a seabird's life.”

In May 2021, a 9-cm-long plastic pony toy, which had been regurgitated by a parent, was found in a chick's nest.  Fortunately, in that case the chick did not swallow it, Broni said.

"DOC staff found plastic in almost all the [albatross] chick regurgitations checked last season.  The most common plastics seen were bottlecaps, however items like a plastic syringe were also found.”

Read more on the hatchling's death.  Previous plastic items in addition to the pony toy found associated with Taiaroa Head’s albatrosses have included bottle caps, squid lures, fishing floats, a container tab and the handle of an infant formula scoop.

Plastic pollution was the theme for last year’s World Albatross Day (WAD2023) on 19 June.

154th American Fisheries Conference: call for abstracts

AFS makau updated 2048x1936

Abstract submission has opened for the 154th American Fisheries Conference under the theme, “Conserving Fishes and Fishing Traditions through Knowledge Co-Production”. 

The conference, which is co-hosted by the Western Division and the Pacific Islands Chapter of the American Fisheries Society, is taking place 15 – 19 September 2024 in Honolulu, Hawaii. 

The program contains a broad variety of sessions, “focusing on the past, present, and future of fisheries conservation and management”.

Of particular note to ACAP is Session SP-11: Managing fisheries bycatch of threatened species, organised by Eric Gilman, Fisheries Research Group, The Safina Center.

“Fisheries targeting highly productive species can have profound impacts on co-occurring species also susceptible to capture that have long generation lengths, low fecundity and other life history traits that make them vulnerable to anthropogenic mortality. There has been increasing concern over the sustainability of bycatch mortality of marine megafauna given their vulnerability to exploitation, ecosystem-level cascading effects from declines in abundance and reduced population fitness from fisheries-induced evolution. There has also been increasing attention to risks from bycatch to food, nutrition and livelihood security. The session’s presentations and discussion will cover priority topics in fisheries bycatch science and policy.”

The deadline for abstract submission is 26 April 2024, and registration for the conference will open in April.

For more information about the conference including the program, travel details and abstract submission, please see the conference website, here.

Wisdom, the world’s oldest known Laysan Albatross, still has it – engaging in mutual displays into her 70s

Wisdom, a Laysan Albatross Phoebastria immutabilis on Midway Atoll National Wildlife Refuge’s Sand Island, is the world’s oldest known wild bird.  Now into her 70s, she was sighted wearing her now well-known plastic leg band red Z333 on 18 March 2024, engaging in mutual displays with other Laysan Albatrosses at her former nest site.

“Wisdom was previously last sighted in January 2024 in search of a new mate after her former mate did not return during the early winter 2023 breeding season.  It is extremely unlikely that she will find that one and only “mature” mate so late in the 2024 nesting season but it is not for lack of trying! She truly is one of the grandest of grandmothers in the animal kingdom.”

On 24 and 25 December 2023 Wisdom was seen displaying with an unbanded male, she was first recorded for the 2023/24 breeding season on 03 December last year.  Her last partner, named Akeakamai, has not been seen this and in the two previous seasons and is likely to be no longer alive (click here).  Let’s hope she can find a new mate in the 2024/25 season and breeds once more.

ACAP releases the 2024 World Albatross Day poster: “Marine Protected Areas: Safeguarding our Oceans”

WALD 2024 Poster English 02New Zealand’s Near Threatened Buller's Albatross Thalassarche bulleri and the Vulnerable Short-tailed Albatross Phoebastria albatrus have been chosen as the featured species for 2024’s World Albatross Day celebrations. Both species appear in this year's poster by Geoffry Tyler, as does the EndangeredGrey-headed Albatross Thalassarche chrysostoma

The Albatross and Petrel Agreement is excited to present the poster for this year’s World Albatross Day under the theme, “Marine Protected Areas: Safeguarding our Oceans”. 

The WAD2024 poster was created by South African born Graphic Designer and long-time ACAP collaborator, Geoff Tyler, who also designed ACAP’s World Albatross Day logo, including this year’s commemorative logo marking the Agreement’s 20th year since coming into force.  

The ocean supports an abundance of life and ecosystems, and Geoff’s design beautifully captures the vital connection between albatrosses and the ocean whilst also highlighting the main threat to these incredible birds – fisheries. 

MPAs can assist in improving the conservation status of albatrosses by safeguarding their breeding habitats, critical areas along their migration routes, and by regulating activities like fishing within these protected zones.

Currently, MPAs can only be established by Governments within their own waters, however, with the landmark signature of the Agreement under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction or 'BBNJ treaty', by 84 nations, their creation in waters commonly known as the High Seas will also become possible. 

New Zealand’s Near Threatened Buller's Albatross Thalassarche bulleri and the Vulnerable Short-tailed Albatross Phoebastria albatrus have been chosen as the featured species for 2024’s World Albatross Day celebrations. Both species appear in this year's poster, as does the Endangered Grey-headed Albatross Thalassarche chrysostoma.

Please help spread the word about this year’s World Albatross Day and share our WAD2024 poster to amplify awareness and inspire action for the conservation of these impressive seabirds and the vast ocean they traverse.

The poster is available in the three official ACAP languages of English, French and Spanish, as well as in Japanese to mark the fact that the majority of the Short-tailed Albatrosses, one of the featured albatrosses for WAD2024, breeds on Japan’s Torishima.

The WAD2024 posters and logos can be freely downloaded at a high resolution to allow for printing at the ACAP website, here.  Please note they are only being made available for personal use or when engaging in activities that will aid in drawing attention to the conservation crisis faced by the world’s albatrosses and petrels – when ACAP will be pleased to receive a mention.

ACAP would like to thank, Michelle Risi, Enzo M. Reyes, Ross Wheeler, Michelle Jones and John Klavitter for the use of their photographs in this year’s WAD2024 poster.
