The detection of Mycoplasma sturni and Mycoplasma moatsii from the choana of a barn swallow (Hirundo rustica): a case report

BMC Veterinary Research, 2023
Background Mycoplasmas are found in many different species. Until now 26 avian mycoplasma species have been described, but in the most free ranging bird species the prevalence and significance of Mycoplasma spp. is still unclear. Case presentation In May

Frugivory in Raptors: New Observations from Australia and a Global Review

Birds, 2021
The diets of raptors are some of the best studied and well-known of all bird groups. Raptors are typically carnivores, hunting and feeding on vertebrates and, for some species, invertebrates. Here, we described instances of the Black Kite (Milvus migrans)

Land cover habitat associations of breeding marsh birds and priority waterfowl differ in eastern Canada

Avian Conservation and Ecology, 2022
Waterfowl (ducks, geese, swans) are among the few bird groups showing recent population increases in North America. By contrast, marsh birds (bitterns, rails, grebes) are declining, despite this group appearing to benefit from many of the same ...

Twenty years of coastal waterbird trends suggest regional patterns of environmental pressure in British Columbia, Canada

Avian Conservation and Ecology, 2020
Waterbirds are often used as indicators of ecosystem function across broad spatial and temporal scales. Resolving which species are declining and the ecological characteristics they have in common can offer insights into ecosystem changes and their ...

Non-Invasive Monitoring of the Spatio-Temporal Dynamics of Vocalizations among Songbirds in a Semi Free-Flight Environment Using Robot Audition Techniques

Birds, 2021
To understand the social interactions among songbirds, extracting the timing, position, and acoustic properties of their vocalizations is essential. We propose a framework for automatic and fine-scale extraction of spatial-spectral-temporal patterns of ...
