Shearwaters and petrels (hereafter petrels) are highly adapted seabirds that occur across all the world's oceans. Petrels a threatened seabird group comprising 120 species. They have bet-hedging life histories typified by extended chick rearing periods, low fecundity, high adult survival, strong philopatry, monogamy long-term mate fidelity thus vulnerable to change. Anthropogenic alterations on land at sea led poor conservation status of many with 49 (41%) species based IUCN criteria 61...
Invasive alien species are a major threat to native insular species. Eradicating invasive mammals from islands is feasible and proven approach prevent biodiversity loss. We developed conceptual framework identify globally important for mammal eradications imminent extinctions of highly threatened using biogeographic technical factors, plus novel consider socio-political feasibility. applied this comprehensive dataset describing the distribution 1,184 vertebrate (i.e. those listed as...
Abstract Illegal hunting of migratory birds across the Mediterranean region is a serious international conservation issue with population-level impacts. We analysed photographs posted on social media platforms to assess bird species illegally targeted in Lebanon. During 2011–2023 we reviewed 1,844 publicly by poachers Facebook and Instagram. In these images identified 212 species, which 94% are legally protected. Many concern, 19 listed as threatened or Near Threatened IUCN Red List 33%...
Summary The ʻuaʻu, or Hawaiian Petrel Pterodroma sandwichensis , is an endangered seabird endemic to the Islands. Genetic, morphometric, and behavioural differences have previously been found between different island populations of species. Understanding breeding phenology ʻuaʻu therefore vital for conservation actions targeting To assess on islands Kauaʻi Lānaʻi, two main techniques were used over a 12-year period: direct burrow monitoring cameras. described based this data. On Kauaʻi,...
The island of Kaua'i, Hawaii, USA, holds a large breeding populations the endangered Hawaiian Petrel (Pterodroma sandwichensis) and majority world population threatened Newell's Shearwater (Puffinus newelli). We evaluated island-wide trends both species. For Shearwaters, we considered radar counts at 13 sites between 1993 2013 annual tallies fledglings retrieved after being grounded by light attraction in 1979–2015 (Save Our Shearwaters [SOS] program). Petrels, alone. Radar data indicated...
ABSTRACT Introduced predators are one of the greatest threats facing seabirds worldwide. We investigated effects multiple introduced on 2 endangered seabirds, Newell's shearwater ( Puffinus newelli ) and Hawaiian petrel Pterodroma sandwichensis ), island Kauaʻi, Hawaiʻi, USA. Between 2011 2017, we recorded 309 depredations which 35.6% were by feral cats, 50.2% black rats Rattus rattus 10.4% pigs Sus scrofa ; pigs), 3.9% barn owls Tyto alba ). Cats most destructive because they killed more...

Light attraction impacts nocturnally active fledgling seabirds worldwide and is a particularly acute problem on Kaua‘i (the northern-most island in the main Hawaiian Island archipelago) for Critically Endangered Newell’s shearwater Puffinus newelli . The Save Our Shearwaters (SOS) program was created 1979 to address this issue date has recovered released sea more than 30500 fledglings. Although value of animal welfare clear, as birds cannot simply be left die, no evaluation exists inform...
Marine spatial planning relies on detailed information of marine areas to ensure effective conservation species. To enhance our understanding habitat use by the highly pelagic Bermuda petrel Pterodroma cahow , we deployed GPS tags 6 chick-rearing adults in April 2019 and constructed a suitability model using locations classified as foraging explore functional responses selection environmental variables. We defined 15 trips for 5 individuals, ranging from 1-6 per bird, that included both...
Abstract Illegal hunting is a widespread problem in the Maltese Islands. As well as having significant impact on islands' breeding birds, illegal of migratory birds has wider, international dimension. To investigate Malta we considered entire ring recovery database Valletta Bird Ringing Scheme, from 1920s to present. All records that were ringed overseas and shot by hunters analysed, comprising total 435 84 species 36 countries. The majority these recoveries (91.7%) listed protected...
Light attraction is a well-documented phenomenon affecting seabirds worldwide, with most reported incidents involving juvenile birds grounded around urban areas or brightly lit structures at sea immediately after fledging. However, there little in the literature regarding impact of light on breeding adult land. This paper describes fallout event adults two endangered seabird species due to lights single facility island Kaua'i, Hawaii, and effectiveness subsequent minimization actions once...
Abstract The Newell's shearwater, or ‘A’o Puffinus newelli, is endemic to the main islands of Hawaiian Archipelago and listed as endangered on International Union for Conservation Nature Red List threatened under U.S. Endangered Species Act. Using abiotic biotic environmental variables, we developed a terrestrial habitat suitability model this species Kauai predict that could be suitable in absence anthropogenic threats. In addition, habitat/threat-isolation index incorporating information...
Following a recent large decline in range and numbers, the Twite Carduelis flavirostris is red‐listed bird of conservation concern. An understanding species’ movements between wintering breeding areas essential to underpin effective conservation. The migration patterns two populations were examined: those South Pennines on west coast Lancashire Cumbria. This was achieved by carrying out an intensive colour‐ringing study 2003 2005. Birds wintered predominantly east southeast coasts England....
Summary The ‘a‘o, or Newell’s Shearwater Puffinus newelli, is an endangered shearwater species endemic to the Hawaiian Islands, with 90% of world population found on Kaua‘i. Understanding breeding phenology vital for identifying key periods colony management actions and timing exposure frequency infrastructure threats such as powerline collisions light attraction. We used a combination direct burrow monitoring remote cameras at multiple colonies between 2012 2019 detailed assessment this...
Newell’s Shearwater ( Puffinus auricularis newelli; NESH) and Hawaiian Petrel Pterodroma sandwichensis; HAPE) are listed under the U.S. Endangered Species Act have declined by 94% 78%, respectively, since 1993 due to habitat degradation, predation introduced predators, collisions with powerlines light attraction. Given challenges in protecting nesting birds their rugged montane habitats, it has long been desirable create populations of both species more accessible locations that offer a...
Three juvenile Cory's Shearwaters Calonectris diomedea were fitted with back-mounted satellite tags and tracked during post-fledging migration. The birds spent several weeks in the central Mediterranean before migrating westwards. Two stopped transmitting after 21 35 days; third bird passed through Strait of Gibraltar along West African coast until ceased day 43, by which time it was 114.6 km off 4,390 from Malta. other islands winter further south equatorial waters, eastern South Atlantic...
Summary The Beck’s Petrel Pseudobulweria beckii is a ‘Critically Endangered’ seabird whose breeding sites remain unknown. Historic observations suggest the species’ distribution concentrated in Bismarck Archipelago and particularly southern New Ireland. Over course of two research expeditions 2016 2017 we used on-land at-sea observations, local interviews satellite telemetry to understand species, its movements potential locations. Land-based indicated that area Silur Bay Ireland was...
