Screech Owls - The Screech Owl is generally restricted to the Americas, however we import ours for the purpose of mail carrying. As usual for owls, female screech-owls are usually larger and fatter than the males of their species, with owls of both sexes being compact in size, shape, and height. Screech-owls are generally colored in various brownish hues with usually a whitish, patterned underside, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a grayish- and a reddish-brown morph.
Barn Owls - The Barn Owl is a pale, long-winged, long-legged owl with a short squarish tail. Depending on subspecies, it measures about 25–45 cm (9.8–18 in) in overall length, with a wingspan of some 75–110 cm (30–43 in). Tail shape is a way of distinguishing the Barn Owl from true owls when seen in flight, as are the wavering motions and the open dangling feathered legs. The light face with its heart shape and the black eyes give the flying bird an odd and startling appearance, like a flat mask with oversized oblique black eyeslits, the ridge of feathers above the bill somewhat resembling a nose
Brown Owl - The Brown Owl is a stocky, medium-sized owl commonly found in woodlands across much of Eurasia. Its underparts are pale with dark streaks, and the upper parts are either brown or gray.
Snowy Owl - The Snowy Owl is a yellow-eyed, black billed white bird and is easily recognizable. It is 52–71 centimetres (20–28 in) long with a 125–150 centimetres (49–59 in) wingspan. Also, these birds can weigh anywhere from 1.6–3 kilograms (3.5–6.6 lb).[2] The adult male is virtually pure white, but females and young birds have some dark scalloping; the young are heavily barred, and dark spotting may even predominate. Its thick plumage, heavily-feathered taloned feet, and coloration render the Snowy Owl well-adapted for life north of the Arctic Circle.
Eagle Owl - The Eagle Owl is a large and powerful bird, smaller than the Golden Eagle but larger than the Snowy Owl. It is sometimes titled the world's largest owl, but so is the Blakiston's Fish Owl, which is slightly bigger on average. The Eagle Owl has a wingspan of 138–200 cm (55–71 in) and measures 58–73 cm (23–29 in) long. Females weigh 1.75-4.2 kg (3.9-9.4 lbs) and males weigh 1.5-3.2 kg (3.3-7 lbs). In comparison, the Barn Owl weighs about 500 grams (1.1 lbs). The size, ear tufts and orange eyes make this a distinctive species. It has a strong direct flight. The ear tufts of males are more upright than those of females.
