Add them to the (long) list: Barau’s Petrels and Tropical Shearwaters also ingest plastic particles

Audrey Cartraud (Université de la Réunion, UMR ENTROPIE, Saint-Denis, Reunion Island, France) and colleagues have published in the Marine Pollution Bulletin on ingestion of plastic by seabirds in the western Indian Ocean, including globally Endangered Barau’s Petrels Pterodroma baraui and Tropical Puffinus bailloni (Least Concern) as well as Wedge-tailed Shearwaters Ardenna pacifica  (Least Concern).

The paper’s abstract follows;

“We investigated seabird plastic ingestion in the western Indian Ocean by analyzing the stomach contents of 222 individuals belonging to nine seabird species (including two endangered species endemics to Reunion Island). The most affected species were tropical shearwaters (79%) and Barau's petrels (59%). The average number of plastic particles per containated bird was higher in Barau's petrels (6.10 ± 1.29) than in tropical shearwaters (3.84 ± 0.59). All other studied species also showed plastic presence in their stomach contents. The mass of plastic particles was significantly higher both in juvenile's Barau's petrels and tropical shearwaters than in adults. These results demonstrate the foraging areas of seabirds of the western Indian Ocean have a high level of plastic pollution. In Reunion Island, hundreds of tropical shearwaters and Barau's petrels are attracted by urban lights and die each year. We suggest taking advantage of this situation by using these species as long-term indicators of plastic marine pollution in the region.”

Chile’s new Diego Ramírez-Drake Passage Marine Park will help protect Black-browed and Grey-headed Albatrosses

The Government of Chile announced earlier in the year the creation of a new 144 390-km² Marine Protected Area (MPA), to be known as the Diego Ramírez-Drake Passage Marine Park (Parque Marino Diego Ramírez y Paso Drake).  Located in the Magallanes Region, it is the southernmost park in South America.

The Diego Ramírez-Drake Passage Marine Park

The government decree grants legal protection to the submerged continental escarpment that drops into the Drake Passage off the southern coast of Chile, as well as to the Sars Seamount (Monte submarino Sars).  The marine park also includes the sub-Antarctic Diego Ramírez Islands (archipiélago Diego Ramírez), which support globally significant breeding populations of ACAP-listed Black-browed Thalassarche melanophris (Least Concern) and globally Endangered Grey-headed T. chrysostoma Albatrosses (click here).  Southern Giant Petrels (Least Concern) have also been reported breeding in the Diego Ramírez group.

Hope for a new colony: two Black-footed Albatrosses seen courting within the Kaena Point Natural Area Reserve

Two Black-footed Albatrosses Phoebastria nigripes are being seen regularly within the Kaena Point Natural Area Reserve on the Hawaiian island of Kauai, according to a Facebook posting by the NGO Pacific Rim Conservation which monitors breeding Laysan Albatrosses P. immutabilis within the reserve.

One bird has been seen in the predator-proof fenced reserve since early January (banded purple V541) and was joined by a second Black-footed Albatross in mid-February. The two birds have been seen undertaking courtship dances regularly.  A few Black-footed decoys have been present for some years and the occasional bird has been seen on site since at least 2013.

Because the majority of Black-footed Albatrosses breeds on low-lying atolls, the establishment of a breeding colony at Kaena Point, protected from predicted sea level rise by its altitude, would add to the efforts being made to establish another colony on Oahu, by hand-rearing translocated Back-footed Albatross chicks in the James Campbell Wildlife Refuge (click here). This project, also operated by Pacific Rim Conservation, is now in its third year (click here).

Year three translocating Black-footed Albatross chicks to start a new colony is underway in Hawaii

Twenty-five Black-footed Albatrosses Phoebastria nigripes (Near Threatened) chicks were translocated from Midway Atoll to within a predator-proof fence in the James Campbell National Wildlife Refuge on the Hawaiian island of Oahu on 16 February this year.  The downy chicks were taken from sites close to the sea’s edge, where they were considered at risk to storm surges and thus unlikely to survive to fledging.  The chicks are being  hand-fed on a special diet* until they fledge.  Following a short indoor period the chicks have now been moved out-of-doors, protected from "from the cold rain and scorching sun" by wooden A-frames, as described and illustrated on Pacific Rim Conservation's Facebook Page.

Earlier postings to ACAP Latest News describe the first two years of Black-footed translocations, with 15 chicks in 2017 and 25 in 2018; 36 of these fledged.  Watch a six-minute video describing the 2017 translocation hand-rearing Black-footed Albatrosses.

The effort to create a new Black-footed Albatross colony considered safe from sea-level rise is being undertaken by the NGO Pacific Rim Conservation in partnership with the US Fish & Wildlife Service.

An extract from Pacific Rim Conservation’s Annual Report for 2018 follows that summarises the goals and activities of the NGO’s seabird conservation programme:

“The goals of the No Net Loss initiative are twofold: 1) to protect as much seabird nesting habitat in the main islands as is being lost in the Northwestern Hawaiian Islands because of the effects of climate change; and 2) to establish new breeding colonies of seabird species that are safe from sea level rise and non-native predators. We do this by building predator exclusion fences, removing invasive predators, and then attracting or translocating birds into these protected areas.”

Life after entanglement: Antipodean Albatross Orange 512, now 24, gets regularly sighted off Kaikoura

On 8 October 2010 a globally Endangered (and Nationally Critical) Antipodean Albatross Diomedea antipodensis of the subspecies gibsoni carrying identifying band Orange 512 was spotted at sea off Kaikoura on New Zealand’s South Island entangled with “her legs caught in hundreds of metres of multi-strand poly-nylon fishing line”.  The bird was caught, the line removed and the bird was then released back to sea by Albatross Encounter Kaikoura skipper and guide, Gary Melville (click here).

Orange 512 was first seen off Kaikoura as a three-year old in December 1998.  It was banded as a chick close to fledging in the Mount Dick colony on Adams Island, Auckland Islands group on 24 December 1996 by Graeme Taylor and Kath Walker.  The bird has been spotted before and after the entanglement incident many times making it a regular visitor to Kaikoura (click here).

The latest news, posted earlier this month comes from the Albatross Encounter Kaikoura Facebook page:

“It has been great to see Orange 512 over the past few days.  This female Gibson’s albatross is 24 years old. She is one of our regulars and like family to us!  First sighted by us when she was 3, she is one of our most frequently sighted banded birds here in Kaikoura!”

Nice to see an ageing lady doing well.
