The barn owl (Tyto alba) is the most widely distributed species of owl, and one of the most widespread of all birds. It is also referred to as the common barn owl, to distinguish it from other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls (Strigidae). The barn owl is found almost everywhere in the world except polar and desert regions, Asia north of the Himalayas, most of Indonesia and some Pacific islands.
Phylogenetic evidence shows that there are at least three major lineages of barn owl, one in Eurasia and Africa, one in Australasia and one in the New World, and some highly divergent taxa on islands. Some authorities further split the group, recognising up to five species, and further research needs to be done to clarify the position. There is a considerable variation between the sizes and colour of the approximately 28 subspecies but most are between 33 and 39 cm (13 and 15 in) in length with wingspans ranging from 80 to 95 cm (31 to 37 in). The plumage on head and back is a mottled shade of grey or brown, the underparts vary from white to brown and are sometimes speckled with dark markings. The face is characteristically heart-shaped and is white in most species. This owl does not hoot, but utters an eerie, drawn-out shriek.
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 true owls or typical owls, Strigidae; and the barn-owls, Tytonidae.
Owls possess large forward-facing eyes and ear-holes; a hawk-like beak; a flat face; and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted in order to sharply focus sounds from varying distances onto the owls' asymmetrically placed ear cavities. Most birds of prey have eyes on the sides of their heads, but the stereoscopic nature of the owl's forward-facing eyes permits the greater sense of depth perception necessary for low-light hunting. Although owls have binocular vision, their large eyes are fixed in their sockets—as are those of other birds—so they must turn their entire head to change views. As owls are farsighted, they are unable to see clearly anything within a few centimeters of their eyes. Caught prey can be felt by owls with the use of filoplumes—like feathers on the beak and feet that act as "feelers". Their far vision, particularly in low light, is exceptionally good.

We’re broken down on our knees
Broken down for all to see
Broken down nowhere to go
Not a prayer
Not a hope
Not a prayer to ever know
What the sun feels like
What it is to be alive
1, 2, 3, Go!
We won’t live forever
We won’t take it anymore
And the silence will be broken
We won’t live forever
We won’t take it anymore
And the silence will be broken here once more
We’re broken down, price to pay
Broken down another day
Broken down a life on hold
Lost our minds
Torn apart
Can’t find a way to make this ours
Look into these eyes
Now it’s time we come alive
1, 2, 3, Go!
We won’t live forever
We won’t take it anymore
And the silence will be broken
We won’t live forever
We won’t take it anymore
And the silence will be broken here once more
We don’t know where we go
It’s still in our souls
Nowhere to turn to
When will we give in? Yeah!
We won’t live forever
We won’t take it anymore
And the silence will be broken
We won’t live forever
We won’t take it anymore
