Manx Shearwater at sea, photograph by Joe Pinder

Martyna Syposz and Oliver Padget (Department of Biology, Oxford University, UK) have published early view in the journal Seabird on the fate of banded Manx Shearwaters Puffinus puffinus grounded by unfavourable weather conditions or exposure to artificial light.

The paper’s abstract follows:

“Manx Shearwaters Puffinus puffinus, like other procellariiform seabirds, spend most of their lives at sea and are encountered on land only when breeding at colonies or if they are grounded due to unfavourable weather conditions or exposure to artificial light. Here, we used historical ringing data to explore the age class structure and spatial patterns of Manx Shearwater groundings and examined ringing and recovery data to identify records of post-grounding survival for first-year and adult birds. We noted 35 cases, out of 6,381 ringed grounded shearwaters, where a bird went on to be recaptured, including two individuals that were later recorded as having successful breeding attempts. While this constitutes only a small number of birds confirmed to have survived following grounding, it is likely to be a considerable underestimate of survival considering the low probability of recapturing a surviving shearwater. Finally, we found that a greater proportion of grounded birds were first-years compared to adult shearwaters, and that adults were found to be grounded further away from colonies than first-year birds. This may be indicative of differential impacts of light pollution at different life stages.”

Kauai’s sixth Small Indian Mongoose, live trapped on 05 May 2023, photograph from the Hawai’i Department of Health

The Hawaiian island of Kaua’i is home to important breeding populations of Endangered Hawaiian Petrels Pterodroma sandwichensis and Critically Endangered Newell’s Shearwaters Puffinus newelli. On the island both seabird species are at risk to predation by feral cats and domestic pigs, but not as yet to mongooses.

Small Indian Mongooses Urva auropunctata were first introduced in 1883 to the main Hawaiian Islands from Jamaica (although native to Asia) to control rats in sugarcane fields. They are now widespread on the Big Island of Hawaii, Oahu, Maui and Molokai. Kauai so far remains free of an established population. However, at least six mongooses have been definitely recorded on Kauai over the last five decades as listed below (click here for more details). Five of the six have been live-trapped and then euthanized by the Hawai’i Department of Health – Vector Control Branch and the Kaua’i Invasive Species Committee after initial sightings. The most recent mongoose on Kauai was caught after a week from its initial sighting this month by deploying no less than 43 live traps. In addition, there have been hundreds of unconfirmed sightings on the island since 1968, raising concerns there could be a breeding population in existence. However, biological evidence for this is said to be scant, following an island-wide status review that also developed standard response protocols for sightings .

Delegates attending the Thirteenth Meeting of the ACAP Advisory Committee gather for the official photo outside Queen Elizabeth House, Edinburgh, Scotland, photograph by Bree Forrer

Two-weeks of intense and productive talks concluded in Edinburgh, Scotland with the Thirteenth Meeting of the ACAP Advisory Committee (AC13) adopting its report last Friday. 

AC13 spent last week considering the recommendations put forward in the reports from its Working Group meetings held the previous week. The reports of the Seabird Bycatch (SBWG11) and Population and Conservation Status (PaCSWG7) Working Groups and the joint meeting of both Working Groups (Joint SBWG11-PaCSWG7) are now available on the ACAP website (see AC13 Docs 9, 11 & 12).  The report of the ACAP Taxonomy Working Group (AC13 Doc 10), which conducts its business online, was also considered by the Advisory Committee.

The report of the 13th Meeting of the Advisory Committee in the three official languages of English, France and Spanish will be published on the ACAP website.

The day before report adoption, delegates were treated to a superb day out to the Scottish Seabird Centre, a conservation and education charity located approximately an hour east of Edinburgh in the pretty seaside town of North Berwick. The centre manages several islands that are home to internationally important breeding seabird populations.

Delegates enjoyed a presentation from the centre and explored its interactive education facilities before heading out on a boat trip around the islands of Bass Rock and Craigleith. The iconic Bass Rock is a steep volcanic monolith which has supported up to 150 000 Northern Gannets, plus smaller numbers of European Shags, Common Guillemots (Common Murres) and Razorbills. Craigleith, one of the smaller islands in the chain is inhabited by a variety of seabirds, including the crowd favourite, the Atlantic Puffin.

In May 2022, the Highly Pathogenic Avian Influenza (sub-type H5N1) was confirmed on Bass Rock and thousands of Northern Gannets became infected and died. Staff at the Seabird Centre are hoping to carry out a census over the coming summer to gauge population numbers.

The outing, though sobering with the knowledge of the devastation caused by H5N1 in seabird colonies in Scotland and across the world, was thoroughly enjoyed by delegates who witnessed thousands of seabirds in their natural habitats. The day was a poignant reminder of the importance of continuing to strive for the conservation of albatrosses and petrels against the many threats they face.

Continuing with its outreach to Asian high-seas fishing countries, the Albatross and Petrel Agreement is today releasing its set of 12 freely downloadable photo posters for this year’s World Albatross Day with its theme of “Plastic Pollution” in the Indonesian language, known as Bahasa Indonesia. This latest release follows versions in Japanese and Korean. Previously, the poster set has been made available in ACAP’s three official languages of English, French and Spanish, as well as in Portuguese. The ‘WAD2023’ logo is also available in Indonesian, and in the other six languages.

View and download the WAD2023 photo posters in Indonesian and in the other six languages here.  They are also available in individual language albums on the ACAP Facebook page.

Indonesia is not a Party to the Agreement, nor has a breeding population of an ACAP-listed species. However, it is an ACAP range state* by way of undertaking fishing that interacts with ACAP-listed species, notably through its high-seas longline fisheries for tuna in the Indian and Pacific Oceans (click here). Indonesia is a member of the Commission for the Conservation of Southern Bluefin Tuna (CCSBT), the Indian Ocean Tuna Commission (IOTC) and the Western and Central Pacific Fisheries Commission (WCPFC). All these Regional Fisheries Management Organizations that manage high-seas tuna stocks (tRFMOs) have adopted seabird bycatch mitigation measures that apply to their member states.

ACAP has made its Seabird Bycatch Mitigation Fact Sheets available in Indonesian. An Indonesian version of the ACAP Seabird Bycatch ID Guide is also planned.

It is hoped the photo posters can be used within Indonesia to increase awareness of the conservation plight being faced by albatrosses and petrels and to aid the country in celebrating World Albatross Day on 19 June.

The photo poster set will be released in Simplified and Traditional Chinese in June, completing this year’s outreach to Asia in support of World Albatross Day on the 19th.

* “Range State” means any State that exercises jurisdiction over any part of the range of albatrosses or petrels, or a State, flag vessels of which are engaged outside its national jurisdictional limits in taking, or which have the potential to take, albatrosses and petrels” [from the Agreement text].
