Nicholas Daudt (Department of Marine Science, University of Otago, Dunedin, Aotearoa, New Zealand) and colleagues have published open access in the journal Estuarine, Coastal and Shelf Science on seabird assemblages off the east coast of South Island, New Zealand.  Albatrosses and petrels tended to occur offshore (>35 km).

The paper’s abstract follows:

“Understanding the relationships between organisms and their environment is crucial to determining important areas for conservation and monitoring. In rapidly changing oceans, one approach to quantify these relationships is to identify species assemblages. This study used a nine year dataset of seabird observations sampled approximately every two months during a cross-shelf transect to describe assemblages at the Subtropical Frontal Zone, in southeast Aotearoa/New Zealand. During 36 voyages, 47 species and a minimum of 69,025 individual birds were recorded. We used multivariate, model-based ordinations to identify assemblages against spatial (distance from the coast), temporal (season) and environmental (water mass) predictors. The multivariate models suggest that the distance from the coast and seasons explain most of the observed variability. Gulls and shags influenced a coastal assemblage (25 km from the coast), and most albatrosses and petrels were only recorded offshore (35 km). Seasons strongly influenced the assemblages, with 31 of the 39 analysed species classified as migratory or dispersive. Over the nine year dataset, the probability of occurrence of nearly 40% of the analysed species changed, indicating possible changes in the assemblage structure and species’ ranges. This study shows the importance of accounting for seasonality when describing assemblages in regions supporting high proportions of migratory and/or wide-ranging species. The observed changes in the probability of occurrence of several species may be the first evidence for the effects of oceanographic changes recently described for the southwest Pacific Ocean due to above-average warming caused by climate change.”

Hatching statistics are in for the intensively managed colony of globally Endangered Northern Royal Albatrosses Diomedea sanfordi at Taiaroa Head/Pukekura on New Zealand’s South Island.

Of the 47 eggs laid in the current 2025/26 breeding season, a record 40 chicks have hatched giving a hatching success of 85.1%.  One chick died when two days old, with the remaining 39 currently transcending to the post-guard stage.

Petrels and shearwaters make up seabird assemblages off Northeast New Zealand

Nicholas Daudt (Department of Marine Science, University of Otago, Dunedin, Aotearoa, New Zealand) and colleagues have published open access in the Journal of Marine Systems giving the first quantitative data on seabird assemblages off northeast Aotearoa/New Zealand.  Total seabird biomass was strongly influenced by the seasonal occurrence of four medium-sized migratory procellariiforms, including the ACAP-listed and globally Vulnerable Black Petrel Procellaria parkinsoni.

The paper’s abstract follows:

“Migratory species may influence structural components of species assemblages, such as biomass and diversity patterns. A total of 10 ship-based, strip-transect seabird surveys were undertaken in all seasons (2019–2024) off the northeast coast of Northland, Aotearoa/New Zealand. Almost all seabird species recorded were migratory or wide-ranging dispersive (23 of 25). Multivariate model-based ordinations revealed that season primarily explained species assemblages, while including environmental variables such as sea surface temperature and chlorophyll-a (useful proxies for studying seabird distribution) offered little extra explanatory power at the assemblage level. There was no clear spatial pattern in the assemblages, suggesting that the study area was used uniformly by the species present at the time. The total seabird biomass present was strongly influenced by the seasonal occurrence of four medium-sized, migratory procellariiforms: tāiko (black petrel; Procellaria parkinsoni), rako (Buller’s shearwater; Ardenna bulleri), ōi (grey-faced petrel; Pterodroma gouldi) and toanui (flesh-footed shearwater; Ardenna carneipes). The biomass estimates showed an eight-fold increase from winter (243 kg/km) to summer (1885 kg/km). Northland will likely be the first region in Aotearoa/New Zealand to experience the consequences of oceanic warming. The study establishes a baseline against which to measure potential future changes in seabird occurrences. Based on descriptive and modelling approaches, the study demonstrated the role of species’ phenologies in shaping assemblages of seabird species and their impact on total estimated biomass, which may affect ecosystem functioning and energy fluxes.”

John Croxall to be the Keynote Speaker at the Fourth World Seabird Conference

John CroxallJohn Croxall CBE FRS will be the Keynote Speaker at the Fourth World Seabird Conference, to be held in Hobart, Tasmania over 7-11 September 2026.  John is an Emeritus Professor at the Universities of Durham and Birmingham and Founder and Chair until 2020 of the BirdLife International Marine Programme.

“Formerly Head of Higher Predator Studies and Conservation Biology at British Antarctic Survey, where [he] led research into dynamics of Antarctic marine ecosystems, especially the role of seabirds and marine mammals, including pioneering 30-year studies of albatross, penguin and fur seal population and trophodynamics.  [He] used new technology to study foraging behaviour and movements, including multi-species, season and year tracking studies and established global databases to enable collaborative studies and inputs to national, regional and global marine spatial planning.”

John was involved with ACAP in the early days serving as Chair of the First Scientific Meeting associated with the First Meeting of Parties, held in Hobart in November 2004, for which he was an Advisor to the United Kingdom Delegation.

A colour-banded Northern Royal gets spotted in Chilean waters

Dan Mosher has reported on Facebook of photographing an Endangered Northern Royal Albatross Diomedea sanfordi off the coast of Chile.  The bird carried a black plastic band on its left leg engraved with D23.

He writes “I recently returned from a cruise [aboard the] Oosterdam from San Antonio, Chile to the Antarctica Peninsula to Buenos Aires and back again.  I’m a deck-watcher and enjoy seeing and photographing the pelagic seabirds we encounter along the way.  On the return trip from Puerto Montt Chile going [north] toward San Antonio, we came across a tagged royal albatross that was quite close to the ship.  The tag clearly reads D23”.  He adds in a comment that the date was 21 February 2026.

Following enquiries posted to his page, the bird was confirmed to be a Northern Royal Albatross from the Taiaroa Head/Pukekura mainland colony near Dunedin in New Zealand, and that it is a male, hatched in 2023, one of 33 chicks to fledge from the colony that [2022/23] season.

Let’s hope it will return to the colony and eventually commence breeding.
