Predator-prey communities are ubiquitous in ecology, but introduced predators can drive native species to extinction within island systems, prompting the eradication of such exotics. Ecological theory predicts that elimination top-introduced from islands lead counterintuitive decline prey populations through ecological release smaller a process termed "mesopredator release." We show, accordance with mesopredator and counter conservation goals for New Zealand reserve, initial cats on Little...
ABSTRACT Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and Stercorariidae). Methods We collated comprehensive dataset that included 48 pelagic migrating seabird species across Atlantic, Indian, Pacific Southern...
The influence of the Earth's magnetic field on locomotory orientation has been studied in many taxa but is best understood for homing pigeons (Columba livia). Effects experimentally induced and naturally occurring perturbations geomagnetic suggest that are sensitive to changes parameters. However, whether use position determination remains unknown. Here we report an apparent intensity gradient observed from sites around a anomaly. From flight trajectories recorded by GPS-based tracking...
AbstractPetrels are highly mobile seabirds that face many threats and whose conservation is frequently hampered by a lack of understanding their biology at sea. We used combination data from burrow monitoring geolocation-immersion loggers to study the intra-and inter-seasonal distribution behaviour endangered Chatham Petrel (Pterodroma axillaris), breeding on Rangatira Island, New Zealand. Breeding extended November June with pre-laying exodus 35 days; an incubation period 46 days, up five...
Animal telemetry is maturing into a viable method for observing the ocean as it can be used to monitor both environmental conditions and biological metrics along movement trajectories of marine animals. As part Cormorant Oceanography Project, we have augmented biologging tag with an external fast response temperature sensor collect profiles from backs foraging birds. Cormorants dive between 50 250+ times day forage prey so they provide hard-to-match temporal spatial coverage coastal within...
Plastic is a major threat to seabirds and the ingestion of plastic may involve sensory trap, where odours appearance marine plastics can resemble food, or exploit animals' pre-existing biases. Our global survey literature reveals that clear-white most common colour found in ocean also ingested by seabirds. However, our case study seabird diversity hotspot (northern Aotearoa New Zealand) indicates although on beaches, local have more species-specific patterns ingestion. dissections 13 species...
The Auckland Domain is the city’s oldest park and contains over 70 ha of contiguous, mature urban forest. Five-minute bird counts were made across one year within domain forest in 2019 2020 compared with conducted 1987 1988, using same methods at survey sites, to investigate changes structure community. abundance species richness native introduced birds increased between count years there was structural change community driven by increases forest-adapted endemic species, tūī Prosthemadera...

Knowledge of the dynamics long-distance migrations pelagic seabirds is limited. Recent advances in tracking technology have yielded detailed, continuous accounts movements individual over large spatial and temporal scales. We studied timing migration year-round distribution Westland Petrel (Procellaria westlandica), listed by IUCN as vulnerable, with miniature archival light loggers (geolocators) deployed on 10 incubating birds breeding 2007 at Westland, New Zealand. retrieved data from...
Cook's Petrel (Pterodroma cookii), a trans-equatorial migrant endemic to the New Zealand archipelago, is today endangered and restricted island habitats at northern southern extents of its former range. To improve limited knowledge breeding habitat this species, we combined an island-wide survey, mapping capabilities geographic information systems, logistic autologistic analyses examine burrow distribution use world's largest population Petrel, on Little Barrier Island (Hauturu). Our results...
The flesh-footed shearwater Puffinus carneipes is a medium-sized and transequatorial migrant within the Pacific Ocean. We used archival data loggers to study non-breeding migration diving behaviour of three shearwaters following breeding in New Zealand. In early April, birds migrated western North Ocean 23±2 days, occupying core distributions Kuroshio/Oyashio transition system for 91±17 days. Subsequent movements were made into Sea Okhotsk prior return migrations Zealand mid September (19±1...
The Common Diving Petrel (Pelecanoides urinatrix) is an abundant seabird species within New Zealand waters. Breeding in this occurs from late July through to December and adults are thought remain waters during non-breeding months. Yet no studies of the spatial ecology have been undertaken confirm this. We used geolocation loggers with seawater immersion probes characterise year-round distribution activity P. urinatrix two colonies (Kauwahaia Island Burgess Island) northern Zealand. Adult...

Common Diving Petrels (Pelecanoides urinatrix urinatrix) are distributed widely around coastal New Zealand and breed primarily on predator-free offshore islands. Despite their ubiquity, little is known of at-sea foraging movement, as small size frequent diving behaviour have presented logistic challenges to obtaining high-resolution tracking data that reflect detailed movement patterns. We present the first attempt collect (5 min/fix) trajectories Petrels, using miniaturised global...
Identification of breeding sites remains a critical step in species conservation, particularly procellariiform seabirds whose threat status is global concern. We designed and conducted an integrative radiotelemetry approach to uncover the grounds critically endangered New Zealand Storm Petrel Fregetta maoriana ( NZSP ), considered extinct before its rediscovery 2003. Solar‐powered automated radio receivers hand‐held telemetry were used detect presence birds on three island groups Hauraki...
