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

The evolution of an “owl‐like” auditory system in harriers: Anatomical evidence
Journal of Anatomy, EarlyView.Harriers hunt relying on sound, with an accuracy to localize sound sources comparable with owls. To assess whether they have owl‐like auditory specializations, we analyzed brain and skull structures using histology and microCT scans. Harriers possess an enlarged external acoustic meatus and significantly expanded auditory brainstem nuclei, up to 12 ...

Ecology and Evolution, Volume 15, Issue 8, August 2025.This article is a systematic review of wild birds breeding success under high temperatures. We highlight the influence of the local climate and emphasize the need to disentangle direct (i.e., through thermoregulation) and indirect effects (i.e., through phenology or trophic relationship).

Journal of Morphology, Volume 286, Issue 8, August 2025.The avian quadrate plays a critical role in cranial kinesis, but few comparative studies exist of its morphological variation across higher‐level taxa. In this study, the occurrence of a markedly concave articular facet of the condylus medialis is surveyed across neornithine birds.

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 ...

BMC Evolutionary Biology, 2015 AbstractBackgroundPrevious cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1–10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive synteny disruptions and associations.

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 ...
