Hunting, but not outdoor recreation, modulates behavioural tolerance to human disturbance in Alpine marmots Marmota marmota

Wildlife Biology, Volume 2026, Issue 2, March 2026.
Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.

West Nile Virus Temperature Sensitivity and Avian Virulence Are Modulated by NS1-2B Polymorphisms.

PLoS Neglected Tropical Diseases, 2016
West Nile virus (WNV) replicates in a wide variety of avian species, which serve as reservoir and amplification hosts. WNV strains isolated in North America, such as the prototype strain NY99, elicit a highly pathogenic response in certain avian species,

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Declining Mortality in American Crow (Corvus brachyrhynchos) Following Natural West Nile Virus Infection

Avian Diseases, 2009
The American crow (Corvus brachyrhynchos) is known to suffer 100% mortality from infection with the New York 1999 strain of West Nile virus (WNV). Following the initial detection of WNV in North America in 1999, we measured prevalence of WNV-reactive antibodies ("seroprevalence") in free-ranging American and fish crows (Corvus ossifragus) of central ...

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Does Seasonal Variation in Agility of Avian Prey Influence Body Size of Breeding Male Cooper's Hawks? And Comments on the Putative Influence of Avivory on Reproductive Output in Cities

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Our findings regarding prey of breeding Cooper's Hawks in British Columbia and Wisconsin expand knowledge of their food habits and support the premise that seasonal agility of prey influences body size of nesting males. We deem it untenable to assume greater production of young at urban vs. rural nests based on proportion of avian prey use.

Seasonal variation in coprophagic foraging in alpine choughs Pyrrhocorax graculus

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Coprophagy, defined as the ingestion of faeces sourced from either self (autocoprophagy), conspecific animals (allocoprophagy), or heterospecific animals (heterocoprophagy), is recognized as a physiological adaptation that enhances nutritional intake and may contribute to gut microbiome stability.

Falcons reduce pre‐harvest food safety risks and crop damage from wild birds

Journal of Applied Ecology, Volume 62, Issue 12, Page 3327-3340, December 2025.
In the absence of American kestrels, there are more birds in orchards. This leads to increased crop damage and more bird faecal contamination. Abstract Foodborne illness outbreaks have heightened pressures on growers to improve food safety, including mitigating possible threats from wildlife. Among wildlife, birds are particularly challenging to deter,

A generalized modeling framework for spatially extensive species abundance prediction and population estimation

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Spatially explicit estimates of species abundance and distribution are increasingly needed to support conservation planning and management across multiple spatial scales. We present a generalized modeling framework that bridges the gap between local studies and regional to national planning by compiling and harmonizing diverse datasets to ...

Experimental West Nile Virus Infection in Blue Jays (Cyanocitta cristata) and Crows (Corvus brachyrhynchos) [PDF]

Veterinary Pathology, 2004
Ten crows ( Corvus brachyrhynchos) and three blue jays ( Cyanocitta cristata), species indigenous to North America, were intravenously inoculated with 103 PFU of West Nile virus (WNV) strain NY99 for production of positive tissues for Canadian surveillance. Both species developed clinical signs 4 days postinoculation (dpi). Virus was detected in blood,
