Surviving in a changing world: weather and juvenile condition matter for a long‐lived avian predator, but blood parasites do not appear to

open access: yesOikos, EarlyView.
Survival is commonly the most critical factor influencing population growth in long‐lived species. Hence, identifying factors shaping variation of survival rates is crucial to understand and predict population trajectories in a changing world. We investigated the factors influencing survival in a long‐lived diurnal bird of prey, analysing the effectsof

Evidence of Songbird Intoxication From Rozol Application at a Black-Tailed Prairie Dog Colony [PDF]

open access: yes, 2013
Concerns about avian poisonings from anticoagulant rodenticides have traditionally focused on secondary poisoning of raptors exposed by feeding on contaminated mammalian prey.

Updating known distribution models for forecasting climate change impact on endangered species [PDF]

open access: yes, 2013
To plan endangered species conservation and to design adequate management programmes, it is necessary to predict their distributional response to climate change, especially under the current situation of rapid change.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Encouraging native predators of invasive yellow‐legged hornets: breeding habitat preferences of European honey buzzards in exotic Eucalyptus plantations

open access: yesPest Management Science, EarlyView.
Our study revealed a positive relationship between the structural complexity of forest plantations and their capacity to deliver regulating ecosystem services. The likelihood of occurrence and the density of breeding pairs of European honey buzzards increased in proportion to the structural complexity of Eucalyptus forest plantations: large trees ...

The untapped potential of camera traps for farmland biodiversity monitoring: current practice and outstanding agroecological questions

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Through a systematic literature review, we show that camera traps (CTs) have been underutilised for farmland biodiversity monitoring. The few existing farmland‐based CT studies focused on local‐level management issues, such as disease transmission between wildlife and livestock, crop damage and use of artificial feeders and water troughs by wildlife ...

A 10,000 Mississippi Kite flock observed in Fuerte Esperanza, Argentina [PDF]

open access: yes, 2006
The Mississippi Kite (Ictinia mississippiensis) is a Neotropical migrant that nests singly or in loose, small colonies in North America from North Carolina and north Florida west to Kansas, southeastern Colorado, and Texas and north along Mississippi ...

Molecular characterization of Trichomonas gallinae isolates recovered from the Canadian Maritime provinces’ wild avifauna reveals the presence of the genotype responsible for the European finch trichomonosis epidemic and additional strains [PDF]

open access: yes, 2015
Finch trichomonosis, caused by Trichomonas gallinae, emerged in the Canadian Maritime provinces in 2007 and has since caused ongoing mortality in regional purple finch (Carpodacus purpureus) and American goldfinch (Carduelis tristis) populations ...

First case report of mortality in an egg‐incubating boreal owl (Aegolius funereus) due to combined Yersinia pseudotuberculosis and Sarcocystis spp. infections

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract Records of lethal consequences from bacterial and parasitic infections in wildlife are scarce, and the conditions under which pathogens cause mortality in infected animals remain poorly understood. We report the first documented case of a female boreal owl (Aegolius funereus) incubating eggs that died on the nest due to a co‐infection with ...
