Investigation of Lethal Concurrent Outbreak of Chlamydiosis and Pigeon Circovirus in a Zoo

Animals, 2021
During the spring, an outbreak of sudden death involving 58 birds occurred in a zoo. Histopathological examinations revealed variable numbers of intracytoplasmic basophilic microorganisms in the macrophages, hepatocytes, and renal epithelium of most ...

Evidence for strain-specific virulence ofTrichomonas gallinaein African columbiformes

Parasitology, 2022
AbstractInfection by parasites or pathogens can have marked physiological impacts on individuals. In birds, infection may affect moult and feather growth, which is an energetically demanding time in the annual cycle. Previous work has suggested a potential link between clinically visibleTrichomonas gallinaeinfection and wing length in turtle ...

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, Volume 249, Issue 4, Page 705-713, October 2026.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

A karyosystematic study in columbiformes (Aves).

CYTOLOGIA, 1978
The karyotypes of four species of Columbiformes have been analysed. The use of the karyotypes as a tool to help solving the problem of systematic classification is discussed. The cytogenetic date obtained agree with the separation of C. picui, in the Columbina genus, from C. minuta, C. passerina and C. talpacoti, in the Columbigallina genus.

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, Volume 225, Issue 1, September 2026.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.
