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 research from Point Blue Conservation Science shows the significant negative impact that invasive, non-native house mice on the Farallon Islands are having to the threatened ashy storm-petrel. Original modeling by ecologists published today in the journal Ecosphere shows the potential impacts to the petrel's population if mice are allowed to remain. The super-abundant mice encourage migrating burrowing owls to stay on the island, who later in the winter switch from eating mice to preying on […]

How do you identify a soaring scavenger from its flight silhouette, or pinpoint which species of swallowtail has just fluttered by on gossamer wings? These were among the challenges facing the survey teams as they attempted to shine a spotlight on the wildlife treasures concealed within the tropical forests on both sides of the border between Guinea and Liberia.
