The Owls

The Owls have large eyes and ears forward-hole, like a hawk-beak, a flat, and, in general, obviously a circle of feathers to each eye means a disc face. Although the Owls have the binocular vision, their large eyes are firmly in their sockets, as with other birds, and they need to turn her head to change the entire display.

The smallest owl is Elf Owl (Micrathene whitneyi), as little as 31 grams (1.1 ounces) and 13.5 cm (5.3 inches). Some of the pygmies owls are hardly bigger. The largest of the owls are two of the eagle owls, Eurasian Eagle Owl (Bubo bubo) Blakiston and fisheries, Owl (Bubo blakistoni), May, reaching a size of 60-71 cm (28.4) long, have a magnitude of about 2 m (6.6 ft.), and the weight of nearly 4.5 kilograms (10 lbs).

The Owls were, and are unable to see much of anything that only a few centimetres in front of their eyes. Their vision from afar, particularly in poor lighting conditions, is exceptionally good. You can rotate her head 135 degrees in both directions, so they can look beyond their own shoulders.

Different kinds of cool sounds, the wide range of calls owls aid to research or to their presence in potential competitors, and the aid ornithologists and birdwatchers to locate these birds and the recognition of the species. The disk with face to channel, that is, by its prey in their ears. In many ways, these are asymmetrically arranged to find the best location directional (Cotty, 2008).

Owl eggs are usually white and almost spherical, and the spectrum of the number of a few dozen, depending on the species. The eggs are at intervals of 1-3 days and not in the same period started. This explains the great change in the size of the young birds brothers and sisters. The Owls do not build nests, but rather a blanket site breeding areas or leave a nest in the trees, underground buildings or in buildings, stables and caves.

Most owls are night people, actively hunting only a victim under the guise of darkness. Several species of owl, however, are light-sensitive switch or active during the twilight of dusk and dawn, an example is the dwarf Owl (Glaucidium). Some schools are also active during the day; examples are the owl the Terriers (Speotyto cunicularia) and Short-eared Owl (Asio flammeus).
The cog on the edge of an owl attack springs to reduce theft.

A large part of the strategy of the owl-hunting depends on the stealth and surprise. Owls have at least two adjustments in the achievement of the Stealth. First, the color of a faille with owl feathers can be almost invisible under certain conditions. Secondly, margins at the top position of the owl regimes cell wing beats of the owl, making their flight is virtually noiseless. Some fish feed on owls, where this silence is no evolutionary advantage of this lack of adjustment. Eleven of the owls and building the lack of feathers theft quietly.

Once the victim was caught, the owl by strong and powerful beak greenhouses or tongs walk by him, to kill his prey before everything to swallow (unless their too large). The scientists are studying the diet of owls are supported by their habit regurgitate the indigestible parts of their prey (such as bones, heads and fur) in the form of pellets. This owl balls "are often sold by the company in the schools to be dissected by the students as
