Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

Ibis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

Looming-Eye Buoys temporarily reduce the number of fish-eating seabirds in pound nets [PDF]

Royal Society Open Science
Seabird depredation in fishing gear and aquaculture facilities is documented worldwide and can represent important revenue losses. Although sometimes considered a nuisance, seabirds are also generally protected, so the development of non-lethal methods ...

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

Ibis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

Experience and trust: the benefits of mate familiarity are realized through sex-specific specialization of parental roles in Cassin’s auklet

Royal Society Open Science
Maintaining a pair bond year after year (perennial monogamy) often enhances reproductive success, but what familiar pairs are doing differently to improve success is unknown.

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

Ibis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

The complete mitochondrial genome of the Band-rumped Storm Petrel (Oceanodroma castro)

Mitochondrial DNA. Part B. Resources, 2019
In this study, we report the complete mitochondrial genome sequence of the Endangered Band-rumped Storm Petrel (Oceanodroma castro), a globally distributed seabird. The mitogenome is 17,023 bp in length and has a base composition of A (30.5%), T (24.0%),

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...

Long‐term monitoring highlights the positive responses of the seabird community to rat eradication at Tromelin Island, Western Indian Ocean

Conservation Science and Practice
The eradication of rats (Rattus norvegicus, R. exulans and R. rattus) on islands is essential for the preservation of island ecosystems, including seabird populations, which are particularly vulnerable to rat predation.

Convergent mutations underpin the repeated evolution of brown plumage in seabirds

Ibis, EarlyView.
Recent genetic data have provided crucial insights into the evolution of animal colour phenotypes, with the melanocortin‐1 receptor (MC1R) frequently implicated in dramatic colour shifts. However, the extent to which similar phenotypes are underpinned by convergent mutations at this locus remains unclear.
