Oiled! A satellite-tracked Black-footed Albatross does not make it home

Unlike for some lower-latitude penguin species, contamination by oil has not been as a serious threat facing ACAP-listed albatrosses, petrels and shearwaters although sporadic cases do get reported (click here for an example, see also here).

A recent example of an oiled procellariiform is of the corpse of a Black-footed Albatross Phoebastria nigripes, stranded on Beverly Beach, where it was collected by the Oregon Department of Fish & Wildlife.  It was individually identified by its federal metal-band and was still equipped with a Microwave Telemetry satellite transmitter.

The oiled bird was one of several  (out of an original 10) Black-footed Albatrosses that were satellite-tagged on Laysan Island in February and have continued to transmit from sea for over three months, as shown by their recent movements (visit NOAA's Animal Telemetry Network site).  One of these birds was exposed to an oil spill off Oregon and Washington , and stranded on Beverly Beach, where its corpse was collected by the Oregon Fish & Wildlife.

Another banded Gibson’s Antipodean Albatross is identified at sea

A colour-banded great albatross Diomedea sp. was photographed at sea over the Queensland Guyot (an extinct volcanic seamount approximately 200 km off the Australian coastal city of Brisbane in the Coral Sea) on 4 May 2024.  The bird carried the colour band Red-94H on its right leg and metal band R-58554 on the left.

Kath Walker, New Zealand Department of Conservation confirms the bird is a Gibson’s Antipodean Albatross D. antipodensis gibsoni.  She writes: “Great to see the band recovery and photograph.  Red-94H is an adult female Gibson’s who we banded in our study area on Adams Island, Auckland Islands on 7 January 2017 when she started nesting there.  She nested successfully in 2023 so was on sabbatical when seen in 2024”.

"This bird is part of a long-term study by Graeme Elliott and Kath Walker on Gibson’s Albatross which are endemic to the Auckland Island archipelago. Since 1991 this study has monitored the survival, productivity, recruitment and population trends of this species on an almost annual basis."

Cristián Suazo (Department of Animal Ecology & Systematics, Justus Liebig University Giessen, Germany) and colleagues have published open access in the journal Polar Biology on a pair of breeding White-capped Albatrosses Thalassarche steadi that successfully fledged their chick on the Diego Ramírez Islands,  The island group was designated as a Marine Protected Area in 2019.

The paper’s abstract follows:

“Albatrosses are renowned for their high philopatry, which has been proposed as a major barrier to their dispersal and hybridization with other albatross species.  Except for shy-type albatross species from New Zealand, examples of colonization of new breeding sites and interbreeding with closely related species are rare.  During the austral summer of 2022, while conducting land-based monitoring of resident Black-browed (Thalassarche melanophris) and Grey-headed (T. chrysostoma) albatross populations on the Diego Ramírez Islands, Chile (56 S), we documented the first (and southernmost) breeding record of a nesting pair of White-capped Albatross (T. steadi), a species endemic to the Auckland Islands, New Zealand (~ 7000 km away).  The species identity was confirmed through molecular analysis.  This discovery underscores the importance of Diego Ramírez and its surrounding waters as a hotspot for global albatross conservation.”

Peruvian Diving Petrels Pelecanoides garnotii have returned to breed on Chile’s Pajaros Uno Island following the eradication of Black Rats Rattus rattus in 2020, confirmed as successful two years later (click here).  Two pairs of have been found breeding this year on the 70-ha island”.  “The audio recordings were played on a specialised solar-powered sound system and during the night when the sea was calm the sounds could be heard up to 300 metres away from the island.”

The island also supports breeding populations of Peruvian Boobies Sula variegata, Kelp Gulls Larus dominicanus and Humboldt Penguins Spheniscus humboldti.

A colour-banded Gibson’s Antipodean Albatross gets photographed at sea - and tells a story

On 5 May 2024 Hannah Fairbairn photographed a great albatross Diomedea spp. at sea while seabird watching on a “pelagic trip” aboard the Jaymar Star of Port MacDonnell Fishing Charters operating out of Port MacDonnell, South Australia to the continental shelf break approximately 30 km offshore, as reported on the Port MacDonnell Seabirds and Pelagics - South Australia Facebook Page.  The bird carried a metal band on its right leg and plastic colour band black 24J on its left.  Read a trip report of the outing here.

White lettering on black colour bands is recorded by the New Zealand National Bird Banding Scheme as being used on the Gibson’s subspecies of the Antipodean Albatross D. antipodensis gibsoni on Adams Island in the Auckland Islands group, where Black 24J was banded as a chick on 11 December 2022 by well-known albatross researchers, Graeme Elliott and Kath Walker.  The sighting is apparently the first time the bird has been reported since its banding.

In response to a query by ACAP Latest News, Kath writes:

“The photo Hannah took of Black-24J at just over two years old is super interesting as we so rarely see birds of that age and haven’t known the timing of the moult of their juvenile brown feathers.  It looks like they must start moulting their dark brown plumage only 6-12 months after they fledge, when they are 16–22 months old.

We’d assumed this to be the case because the longest time we’ve managed to retain satellite transmitters taped onto the back feathers of juvenile Gibson’s Albatrosses just before they fledge is 16 months (i.e. all the juveniles we tracked had moulted out their original back feathers by 25 months of age).

When Graeme and I banded Black-24J it still had quite a lot of down on its neck and belly so we were unsure whether it was a male or a female. However, at 25 months it already looks so white on the back in the photos we think it’s more likely it is a male.”

 Identification of the five taxa of great albatrosses in the “Wandering Group” at sea in regions where more than one taxon is likely to occur will always be difficult, given the subtle differences in appearance, made harder by gender and age changes in plumage.  Thus, confirming an ID made at sea by the presence of leg bands that have been photographed is both useful for learning how to identify the taxa and to add to knowledge of their at-sea distributions.
