Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea. [PDF]

Anat Histol Embryol
ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.

Metagenomic analysis of the gut microbiota of hooded cranes (Grus monacha) on the Izumi plain in Japan. [PDF]

FEBS Open Bio
We analyzed metagenomic sequencing data obtained from fecal samples of hooded cranes and wild ducks that winter on the Izumi Plain in Japan. Various organisms were identified in each sample, and their diversity differs between the crane and duck groups, suggesting that these two bird species may have distinct gut microbiota.

West Nile Virus Monitoring in Flanders (Belgium) During 2022-2023 Reveals Endemic Usutu Virus Circulation in Birds. [PDF]

Transbound Emerg Dis
The recent emergence of West Nile virus (WNV) and Usutu virus (USUV) in some European countries has triggered an increase in animal and human cases across Europe. Wild birds, serving as key reservoirs for WNV and USUV, often act as crucial indicators for the introduction and spread of these viruses. Currently, there is no durable large‐scale monitoring

Following the feeder: A global synthesis of disturbance‐based foraging associations of birds

Journal of Animal Ecology, Volume 92, Issue 12, Page 2263-2279, December 2023., 2023
Disturbance foraging has been understudied against the foundation of knowledge that exists on foraging behaviour. Our review represents the first of its kind in analyzing over a hundred years of foraging data to provide insight into the important of geography, phylogeny, and ecology in shaping disturbance foraging behaviour.

Evolution of posture in amniotes–Diving into the trabecular architecture of the femoral head

Journal of Evolutionary Biology, Volume 36, Issue 8, Page 1150-1165, August 2023., 2023
We use 3D microanatomical parameters measured at the femoral head to study femoral posture in amniotes. We show that these parameters are not good indicators of femoral posture. Methods of ancestral state reconstruction hold great promise for improving our understanding of the evolution of posture in amniotes.

Antibody prevalence to avian influenza virus subtypes H5, H7 and H9 in falcons, captive and wild birds, United Arab Emirates, 2003–2006

Veterinary Medicine and Science, Volume 9, Issue 4, Page 1890-1900, July 2023., 2023
Antibody prevalence to Avian influenza virus subtypes H5, H7 and H9 in falcons and wild/captive birds, UAE, 2003–2006. The vertical axis indicates the number of samples investigated. Columns 1–3 depict the prevalence of antibodies in sera of wild and captive birds and columns 4–6 the prevalence in falcon samples.

Global patterns and predictors of avian population density

Global Ecology and Biogeography, Volume 32, Issue 7, Page 1189-1204, July 2023., 2023
Abstract Aim How population density varies across animal species in the context of environmental gradients, and associated migratory strategies, remains poorly understood. The recent influx of avian trait data and population density estimates allows these patterns to be described and explored in unprecedented detail.

Bird genetic databases need improved curation and error reporting to NCBI

Ibis, Volume 165, Issue 2, Page 472-481, April 2023., 2023
The ongoing biodiversity crisis is causing rapid species losses faster than taxonomists' capacity to describe new species. Integrative taxonomic approaches need robust taxonomic baseline data to correctly describe and conserve global species diversity, in which genetic data are one of the pillars.
