Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

open access: yesConservation Biology, EarlyView.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Community‐informed and codesigned research to understand the impacts of railways on wildlife

open access: yesConservation Biology, EarlyView.
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Past research and future directions in understanding how birds use their sense of smell

open access: yesIbis, EarlyView.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Highly Pathogenic Avian Influenza A (H5N1) Infection in Bearded Vultures in Spain

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT We report mortality in bearded vultures (Gypaetus barbatus) associated with highly pathogenic avian influenza HPAI A H5N1 clade 2.3.4.4b, responsible for the current HPAI panzootic. Between April and May 2022, a total of five bearded vultures from Spain, four free‐ranging and one captive individual, were found dead in their nest or with acute ...
