THE ACAP MONTHLY MISSIVE. Pip pip hooray! Looking after hatching eggs and hatchlings in the Northern Royal Albatross colony at Pukekura/Taiaroa Head

The small Northern Royal Albatross Diomedea sanfordi colony on New Zealand’s mainland in the Pukekura/Taiaroa Head Nature Reserve must be one of the most intensively managed seabird colonies anywhere in the world – at least outside attempts to establish new colonies by introductions.  New Zealanders are good at hands-on management, just read up on their successful (and ongoing) efforts to save the Vulnerable Black Robin Petroica traversi, the Critically Endangered Kakapo Strigops habroptilus and the Endangered South Island Takahe Porphyrio hochstetteri from looming extinctions.  Three examples, to which we can add the globally Endangered Northern Royal Albatross.

The Department of Conservation rangers at Pukekura/Taiaroa Head utilize a plethora of interventions to maximise breeding success.  Their hands-on approach with the birds extends throughout the whole breeding season.  These activities fit well with this year’s celebration of World Albatross Day (WAD2026) on 19 June and its theme of “Habitat Restoration”.  It is therefore intended to feature them in ACAP Latest News during the course of the 2025/26 breeding season.

To start off, the process followed with hatching eggs and hatchlings in their first week out of the shell is described here by way of captioned pictures.  This must be the most intensive time during the breeding cycle for the rangers and therefore seems  a good place to start.

No evidence of sex ratio bias in plastic loads of Flesh-footed Shearwater chicks

Alex Bond (Bird Group, Natural History Museum, Tring, United Kingdom) and colleagues have published open access in the journal Marine Pollution Bulletin on a study of plastic pollution in the Near Threatened Flesh-footed or Sable Shearwater Ardenna carneipes, a potential candidate species for ACAP listing.  They found no sex differences in frequency, mass, number, colour or type of ingested plastic.

The paper’s abstract follows:

“Sex-based differences in plastic ingestion by wildlife are understudied.  Studies from the 1980s of birds shot at sea found no sex differences in plastic ingestion by post-fledging and adult birds, but nest-bound age classes remain unstudied.  We quantified plastic ingestion by 114 Sable Shearwaters (Ardenna carneipes) fledglings from Lord Howe Island, Australia, in 2023, and compared the frequency of ingestion, number of pieces, mass, and colour and type composition between sexes.  We found no difference in the frequency of plastic ingestion, the mass, number of pieces, colour, or type composition of ingested plastics between female and male fledglings.  There was no evidence of a sex ratio bias in the sampled population. The genetic sex of chicks is not a predictor of ingested plastics, but the potential for a biased sex ratio among chicks and adults could compound ongoing population declines.”

Midway Atoll’s albatross ground count reveals over 600 000 pairs are breeding in the 2025/26 season – but will the volunteers be replaced by drones and temporal image differencing?

Once more, volunteers have conducted exhaustive ground counts of breeding albatrosses in Midway’s Atoll’s Eastern and Sand Islands.  Results for the 2025/26 season are now in.  Laysan Albatrosses Phoebastria immutabilis numbers were down by 5% from the previous season but were still the fourth highest count for the atoll at 589 623 occupied nests.  “It is not uncommon in a given year for population counts on Midway to increase or decrease by 10 to 25%.”  The Black-footed Albatross P. nigripes count of 28 246 occupied nests is the second highest.

The highest number of Vulnerable Short-tailed Albatrosses P. albatrus ever documented in one year at Midway with a total of eight individuals so far was recorded, including the well-known breeding pair George and Geraldine for their ninth breeding season (watch the video of them mutually allopreening), along with several of their offspring returning as juveniles.

“USFWS staff have confirmed that Wisdom [the world’s oldest-known Laysan Albatross] did not lay an egg this year, though she has been visiting Midway Atoll, including another recent visit.”

Alongside the labour-intensive, and potentially disturbing (requiring the wearing of burrow shoes or “Funny Feet”), annual ground count the drone research project completed its second field season.  “Temporal Image Differencing” by surveying the same areas multiple times allows researchers to compare drone images over time to identify breeding albatrosses from non-breeders, making for more accurate counts of the actual numbers of breeding pairs possible.  Read more about the drone project here with photographs and a video.

Perhaps future albatross counts on Midway will be undertaken only by drones, rather than by a team of volunteers.

You can watch breeding Laysan Albatrosses via a live-streaming camera; access it from here.

Albatrosses in flight use wind and waves differently in two hemispheres

Ian Maywar (School of Marine and Atmospheric Sciences, Stony Brook University, New York, USA) and colleagues have published open access in the journal Movement Ecology on comparing five species of albatrosses' use of wind and waves in the North Pacific and Southern Ocean.

The paper’s abstract follows:

Background

Albatrosses can commute long distances to feed during the breeding season by avoiding energetically costly flapping flight.  Energy from both wind and waves can be used to sustain soaring and reduce flapping flight, yet most studies of albatross flight have focused solely on the influence of wind.

Methods

To examine how wind and waves allow albatrosses to reduce energetic costs by limiting flapping flight, we analyzed how the flap rates of five albatross species (370 individuals) across two ocean basins varied with wind speed and swell height.

Results

For all study species, soaring using both wind and waves resulted in an 89–93% reduction in the number of flaps per hour and thus more energetically efficient flight.  We found notable differences in the relative importance of wind and waves for albatrosses breeding in the Southern Ocean and North Pacific  The flap rates of Southern Ocean species, black-browed (Thalassarche melanophris), grey-headed (T. chrysostoma), and wandering (Diomedea exulans) albatrosses, were better explained by variability in windspeed whereas those of North Pacific species, black-footed (Phoebastria nigripes) and Laysan (P. immutabilis) albatrosses, were better explained by variability in swell height.

Conclusions

Our results suggest that Southern Ocean species relied more on dynamic soaring by exploiting winds whereas North Pacific species relied more on wave-slope soaring using swells.  This divergence in behavior is likely the result of differences in the regional winds and swells between the two ocean basins.  Although windspeeds experienced by albatrosses in both oceans were similar, North Pacific species experienced greater swell heights, likely allowing them to extract more wind energy from waves than albatrosses in the Southern Ocean.  Our research highlights the importance of both wind and waves for albatross movement and the need to better understand environmental impacts on physiological drivers of foraging energetics to assess responses of seabirds to a rapidly changing climate.”
