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

Willow tits survive best with support from a flock
on December 18, 2018 at 2:50 pm
Willow tits (Poecile montanus) generally reside in one territorial area throughout their adult lives. But brutal winters in the north kill off many of them. They aren't able to manage well on their own, and storing seeds in the autumn is not always enough. For the young of the year, it is absolutely vital to find a flock to spend the winter with. Juvenile birds also have to try to become high-ranking members within the flock. […]
