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

- New analysis finds Spotted Owls harmed by...on April 16, 2021 at 8:52 pm
Are forest fires a threat to the imperiled Spotted Owl? For years, different groups of scientists assumed so, but a new study turns this assumption on its head. Researchers from the John Muir Project, Pennsylvania State University, and Wild Nature Institute found that these previous studies consistently had a serious methodological flaw: they failed to take into account the impact of post-fire logging on Spotted Owls.

Since 1993, 15 species of bird and mammal are thought to have gone extinct, including China's Yangtze river dolphin and the Pernambuco pygmy owl from Brazil. But these recent examples are a tiny fraction of what scientists estimate could disappear in the lifetimes of people living today. One million species spanning the full diversity of life on Earth are at risk of extinction.

This spring, longtime Central Park birder and naturalist Gabriel Willow is feeling a little less nervous than he did a year ago.

The Amazon rainforest is teeming with creatures unknown to science—and that's just in broad daylight. After dark, the forest is a whole new place, alive with nocturnal animals that have remained even more elusive to scientists than their day-shift counterparts. In a new paper in Zootaxa, researchers described two new species of screech owls that live in the Amazon and Atlantic forests, both of which are already critically endangered.
- Paraguay's first satellite deployed from the...on March 25, 2021 at 3:37 pm
On March 14, the Paraguayan Space Agency (AEP) deployed a satellite from the International Space Station to help track a tiny parasite that causes Chagas disease. The satellite, Guaranisat-1, is the first developed and put into orbit by Paraguay. An estimated 8 million people in Mexico, Central America, and South America have Chagas disease, which if untreated can be life-threatening. Large-scale population movements from rural to urban areas of Latin America and other parts of the world have […]
