Medical and Veterinary Entomology, EarlyView.We identified Culex pipiens bloodmeals at the species level in natural, agricultural and peri‐urban habitats and calculated host preferences based on forage ratios. This analysis showed Passeriformes, and in particular Columba livia, Passer montanus and Turdus sp., to be the preferred Cx. pipiens hosts.

Ecology and Evolution, Volume 15, Issue 7, July 2025.Montane red foxes (Vulpes vulpes ssp.) native to western North America are of broad conservation interest, but their ecology is poorly understood due to their rarity. We examined the diet of the Sierra Nevada red fox (V. v. necator) in an unstudied portion of their range in Oregon, USA, then evaluated dietary overlap between red fox and coyote (Canis ...

Increased Mortality Rates Caused by Highly Pathogenic Avian Influenza Virus in a Migratory Raptor
Ecology and Evolution, Volume 15, Issue 7, July 2025.We utilized movement data to identify a continental‐scale mortality event caused by highly pathogenic avian influenza virus (HPAIV) in a single species of migratory bird, the rough‐legged hawk (Buteo lagopus). We estimated an HPAIV cause‐specific annual mortality rate of 28% that substantially elevated the overall annual mortality rate (47%) above ...

Breeding biology of Neotropical Accipitriformes: current knowledge and research priorities
Revista Brasileira de Ornitologia, 2018 Despite the key role that knowledge on breeding biology of Accipitriformes plays in their management and conservation, survey of the state-of-the-art and of information gaps spanning the entire Neotropics has not been done since 1995. We provide an updated classification of current knowledge about breeding biology of Neotropical Accipitridae and define

Journal of Animal Ecology, Volume 94, Issue 7, Page 1461-1473, July 2025.Variation in colour complexity in the Paridae is linked to climate, climate variability and several biotic factors. The strength of the associations is patch specific. Variables related to resource competition are more strongly associated with colour complexity of the head and breast than with that of the back and wing.

Assessment of a Social Media‐Based Method for Determining Raptor Diet
Ecology and Evolution, Volume 15, Issue 6, June 2025.This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...
