Discriminating between nesting and non-nesting habitat in a vulnerable bird species: Implications for behavioural ecology [PDF]

, 2019
Nowadays, partitioning amongst nesting and non-nesting habitats is not much studied. Here, I investigate whether or not the turtle dove (Streptopelia turtur) nesting habitats overlap with those used for other purposes in a North African agroforestry ...

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, EarlyView.
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.

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 ...

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

Journal of Anatomy, EarlyView.
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 ...

Molecular epidemiological study of Trichomonas gallinae focusing on central and southeastern Europe

Frontiers in Veterinary Science, 2022
Trichomonas gallinae is a geographically widespread protozoan parasite of birds. In this study, oropharyngeal swab samples were collected in Hungary and Romania from 99 columbiform birds, including 76 feral pigeons (Columba livia domestica: 42 kept for ...

Classification of bird species from video using appearance and motion features [PDF]

, 2018
The monitoring of bird populations can provide important information on the state of sensitive ecosystems; however, the manual collection of reliable population data is labour-intensive, time-consuming, and potentially error prone.

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.

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

A Comprehensive Cytogenetic Analysis of Several Members of the Family Columbidae (Aves, Columbiformes) [PDF]

Genes, 2020
The Columbidae species (Aves, Columbiformes) show considerable variation in their diploid numbers (2n = 68–86), but there is limited understanding of the events that shaped the extant karyotypes. Hence, we performed whole chromosome painting (wcp) for paints GGA1-10 and bacterial artificial chromosome (BAC) probes for chromosomes GGA11-28 for Columbina
