“…Petrels and shearwaters (hereafter petrels) are highly adapted seabirds and one of the most threatened avian groups (Rodríguez et al, ). Petrels have the ability to navigate in the dark and to execute behaviors at various ambient light levels, from underwater foraging to colony visitation at night and underground nesting (Brooke, ).…”

Seabirds are impacted by coastal light pollution, leading to massive mortality events. Juveniles comprise the majority of affected individuals, while adults are only seldom grounded and reported in rescue programs. We propose a connection between visual system development of burrow nesting seabirds and the observed higher vulnerability to light pollution by a specific age group. We illustrate the need for multidisciplinary research to better understand and further mitigate light-induced mortality.

“…Invasive predator eradications from islands often play a key role in seabird conservation, as many seabird species breed on islands, or are even endemic to them (Taylor, ,; Spatz et al ., ; Brooke et al ., ; Rodriguez et al ., ). Seabirds, and notably members of the order Procellariiformes, are one of the most threatened taxonomic groups on the planet (Croxall et al ., ; Rodriguez et al ., ). Many Procellariiformes are K ‐strategists (i.e., low fecundity and high longevity).…”

“…Many Procellariiformes are K ‐strategists (i.e., low fecundity and high longevity). Therefore, these species are highly susceptible to the reduced hatching/fledging success and heightened adult mortality that are typical consequences of invasive predators (Jones et al ., ; Spatz et al ., ; Brooke et al ., ; Rodriguez et al ., ). Smaller species (<1 kg) are especially susceptible to invasive predators (Jones et al ., ).…”

Population growth estimates of a threatened seabird indicate necessity for additional management following invasive predator eradications

The eradication of invasive predators from islands is a successful technique to safeguard seabird populations, but adequate post-eradication monitoring of native species is often lacking. The Whenua Hou Diving Petrel (Pelecanoides whenuahouensis; WHDP) is a recently-described and 'Critically Endangered' seabird, restricted to Codfish Island (Whenua Hou), New Zealand. Invasive predators, considered the major threat to WHDP, were eradicated on Codfish Island in 2000. However, estimates of WHDP population size and trends remain unknown, hindering assessments of the success of the eradications. We collated intermittent burrow counts (n = 20 seasons) conducted between 1978 and 2018. To estimate the population growth rate (k) before and after predator eradications, we used log-linear models in a Bayesian hierarchical framework while retrospectively accounting for differences in detection probabilities among burrow counts, due to differences in effort, marking and timing. The number of WHDP burrows was estimated at 40 (36-46) in 1978 and 100 (97-104) in 2018. The pre-eradication k was estimated at 1.023 (0.959-1.088), while the post-eradications k was estimated at 1.017 (1.006-1.029). The WHDP population appears to be increasing, yet the rate of increase is low compared to other Procellariiformes following predator eradications. The comparatively low post-eradication k, combined with an apparent lack of change between pre-and post-eradication k, indicates that additional threats might be limiting WHDP population growth and that further conservation management is required. The continuation of affordable and simple, albeit imperfect, monitoring methods with retrospective corrections facilitated the assessment of invasive predator eradications outcomes and should guide future management decisions.

“…Introduced predators have been identified as one of the most significant causes for the decline of seabird populations on islands worldwide (Courchamp et al 2003, Croxall et al 2012, Doherty et al 2016, Dias et al 2019, Rodríguez et al 2019). Whereas the species vary on an island by island basis, the most destructive and well‐known introduced seabird predators are feral cats ( Felis catus ), rats ( Rattus spp.…”

Introduced predators are one of the greatest threats facing seabirds worldwide. We investigated the effects of multiple introduced predators on 2 endangered seabirds, the Newell's shearwater (Puffinus newelli) and the Hawaiian petrel (Pterodroma sandwichensis), on the island of Kauaʻi, Hawaiʻi, USA. Between 2011 and 2017, we recorded 309 depredations of which 35.6% were by feral cats, 50.2% by black rats (Rattus rattus), 10.4% by pigs (Sus scrofa; feral pigs), and 3.9% by barn owls (Tyto alba). Cats were the most destructive of the predators because they killed more breeding adults than chicks, which had repercussions on breeding probability in following years. Cats and rats were also the most prevalent of all the predators, depredating birds at all of the sites under consideration regardless of how remote or inaccessible. We also considered the effectiveness of predator control over the study period. Reproductive success at all sites increased once predator control operations were in place and depredations by all species except barn owls decreased. Furthermore, we modeled population trajectories for all sites with and without predator control. Without predator control, population trajectories at all sites declined rapidly over 50 years. With predator control operations in place, populations at all sites increased; thus, controlling introduced predators at endangered seabird colonies is important for their management. © 2020 The Wildlife Society.
