Population Survey Of Southern Buller’S Albatross Thalassarche Bulleri Bulleri On The Solander Islands / Hautere, March 2024, Peter G. H. Frost, Barry G. Baker, Johannes H. Fischer, Paul M. Sagar
Population Survey Of Southern Buller’S Albatross Thalassarche Bulleri Bulleri On The Solander Islands / Hautere, March 2024, Peter G. H. Frost, Barry G. Baker, Johannes H. Fischer, Paul M. Sagar
Marine Ornithology
An aerial photographic survey of the Southern Buller's Albatross Thalassarche bulleri bulleri population breeding on the Solander Islands / Hautere was undertaken on 09 March 2024, mid-way through the birds' incubation period. Overall, 6,761 individuals were counted: 6,215 (92%) on Great Solander and 546 (8%) on Little Solander. Of these, 4,213 were sitting on nests, 368 were partners to sitting birds, 573 were standing near empty nests, and 145 were apparently loafing. The status of the remaining 1,462 individuals (22% of the total) was uncertain. Assuming that their status was in the same proportions to those of the clearly observed …

Marine Ornithology
The density and distribution of Westland Petrel burrows was assessed over a 12-year period (2007–2019). During that time, burrow density increased while occupancy remained stable, commensurate with an annual population growth rate of 1.022 (95% confidence interval: 0.971–1.076), as estimated using mark recapture data. From our surveys, we estimated a 2019 baseline population of ~6200 breeding pairs and a world population of 13 800–17600 individuals, covering around 95% of the population. Transects were conducted to establish the location and density of 17 petrel sub-colonies in rugged, untracked terrain in Paparoa National Park, West Coast, New Zealand. Major storms in 2014–2018 …
Nightly Colony Attendance Patterns Of Provisioning Cassin's Auklet Ptychoramphus Aleuticus Are Consistent And Synchronous, Laura Mcfarlane Tranquilla, John L. Ryder, Louise K. Blight, Patrick D. O’Hara, Douglas F. Bertram
Nightly Colony Attendance Patterns Of Provisioning Cassin's Auklet Ptychoramphus Aleuticus Are Consistent And Synchronous, Laura Mcfarlane Tranquilla, John L. Ryder, Louise K. Blight, Patrick D. O’Hara, Douglas F. Bertram
Marine Ornithology
We conducted a multi-year (1999–2001) radio telemetry study to determine patterns of colony attendance among breeding Cassin’s Auklets Ptychoramphus aleuticus during the chick-rearing period on Triangle Island in British Columbia, Canada. A total of 1 625 detections were obtained for 80 individual birds (24–28 birds per year), each detected 20.3 times on average. We found that colony attendance (arrival times, departure times, in-burrow shift duration) and foraging trip duration (i.e., time away from the colony) were remarkably synchronous among individuals and years. On average, birds arrived in a pulse after darkness, with 67% of returns between 23h15 and 00h15 and …
Decrypting The Breeding Biology Of The Elusive And Declining Tahiti Petrel Pseudobulweria Rostrata, Angelique Pagenaud, Karen Bourgeois, Léna Payandi, Wilfried Weiss, Éric Vidal, Andreas Ravache
Decrypting The Breeding Biology Of The Elusive And Declining Tahiti Petrel Pseudobulweria Rostrata, Angelique Pagenaud, Karen Bourgeois, Léna Payandi, Wilfried Weiss, Éric Vidal, Andreas Ravache
Marine Ornithology
Among procellariids, the Tahiti Petrel Pseudobulweria rostrata is one of the most endangered and least known species. Its global populations are declining, yet demographic and ecological studies remain scarce. Understanding the breeding cycle and behavior of Tahiti Petrel adults and chicks is essential to develop effective protection measures. To address this knowledge gap, Tahiti Petrel colonies of various sizes were studied at three sites in New Caledonia, with extensive sampling at two main sites and limited sampling at a third. A total of 157 burrows were monitored for up to two years using endoscopic cameras and camera traps. This allowed …
