Non-Invasive Sex Determination of Nestlings and Adult Bonelli’s Eagles Using Morphometrics
Animals, 2023 Biometric analysis allows the sexing of most vertebrates, particularly birds. Birds of prey, and, especially, the Bonelli’s eagle (Aquila fasciata), show reverse sexual dimorphism (i.e., females are usually larger than males).

Scientific Reports, 2023 Habitat loss is one of the main threats to species survival and, in the case of parasites, it is their hosts that provide their habitat. Therefore, extinction even at local scale of host taxa also implies the extinction of their parasites in a process ...

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 ...

Ecology and Evolution, Volume 16, Issue 1, January 2026.The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).
