Verreaux's Eagle-Owl - Description

Description

Verreaux's Eagle-Owl is a very large and powerful owl species. It ranges from 60–66 cm (24–26 in) in length. This species has an average wingspan of 140 cm (55 in). The body mass is 1,600–2,000 g (3.5–4.4 lb) in males, with an average of 1,700 g (3.7 lb) against a body mass of 2,500–3,150 g (5.5–6.9 lb), averaging 2,625 g (5.79 lb), in the larger females. Among standard measurements, each wing chord measures 42–49 cm (17–19 in), the tail is 22–27.5 cm (8.7–10.8 in) long and the tarsus is 8 cm (3.1 in).

In appearance, they are distinguished by a whitish oval disk face with a black border and their pink eyelids. Their eyes are orange in color and they have two fluffy ear-tufts. Overall, they are a fairly uniform brownish-gray, with light vermiculations above and white spots on the shoulder. They are paler on the underside.

The male's song is a deep gwok, gwok, gwonk-gwokwokwok gwokwokwok gwonk. The female's call is similar but higher pitched. The alarm calls of both sexes are often a sonorous whok but variable grunting notes and raspy screams also seem to indicate alarm. Both the female and the young engage in high, piercing calls when begging for food at the nest (at which time the male does the food capture).

Famous quotes containing the word description:

    “Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
    —Willard Van Orman Quine (b. 1908)

    “As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
    —Henry David Thoreau (1817–1862)

    “A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
    —John Locke (1632–1704)
