owl : any of an order (Strigiformes) of chiefly nocturnal birds of prey with a large head and eyes, short hooked bill, strong talons, and soft fluffy often brown-mottled plumage — Webster
Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica and some remote islands. Owls are divided into two families: the Strigidae family of true (or typical) owls; and the Tytonidae family of barn-owls. — Wikipedia

Illumination drives bats out of caves, no matter...
on December 11, 2019 at 3:12 pm
Artificial light influences the behavior of many nocturnal animals such as bats, which are very sensitive to all types of lighting. Particularly critical is the illumination of natural caves in which bats roost. Cave illumination is widespread in tourist areas worldwide and disturbs the animals in their resting places. Researchers of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Max Planck Institute for Ornithology (MPIO) have now investigated how the illumination of […]

Birds of a feather may flock together, but the feathers of birds differ altogether.
Dog and sheep bones help injured pigeons fly again
on November 20, 2019 at 4:00 pm
Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons' fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and more efficient than using metal pins for pigeon rehabilitative surgeries, November 20th in the journal Heliyon.
Songbirds sing species-specific songs
on November 12, 2019 at 7:00 pm
The generation of species-specific singing in songbirds is associated with species-specific patterns of gene activity in brain regions called song nuclei, according to a study published November 12 in the open-access journal PLOS Biology by Kazuhiro Wada of Hokkaido University in Japan, and colleagues. According to the authors, the findings could be a promising step toward a better understanding of the contribution of multiple genes to the evolution of behaviors.

Antibiotic resistance has become a global health problem due to decades of misuse of these drugs in both human and veterinary medicine. Nowadays, the prevalence of multi-drug resistant bacteria in humans, domestic animals and livestock has increased, hindering the finding of the correct treatment for infectious diseases that before were not a problem. This is especially true in hospital settings, where antimicrobial pressure is extremely high and patients are immunocompromised and more prone to […]
