 os·trich n.  [Formerly written also estrich.] Zool. A large bird of the genus Struthio, of which Struthio camelus of Africa is the best known species. It has long and very strong legs, adapted for rapid running; only two toes; a long neck, nearly bare of feathers; and short wings incapable of flight. The adult male is about eight feet high.
 Note: ☞ The South African ostrich (Struthio australis) and the Asiatic ostrich are considered distinct species by some authors. Ostriches are now domesticated in South Africa in large numbers for the sake of their plumes.  The body of the male is covered with elegant black plumose feathers, while the wings and tail furnish the most valuable white plumes.
 Ostrich farm, a farm on which ostriches are bred for the sake of their feathers, oil, eggs, etc.

 Ostrich
    (Lam. 4:3), the rendering of Hebrew pl. enim; so called from its
    greediness and gluttony. The allusion here is to the habit of
    the ostrich with reference to its eggs, which is thus described:
    "The outer layer of eggs is generally so ill covered that they
    are destroyed in quantities by jackals, wild-cats, etc., and
    that the natives carry them away, only taking care not to leave
    the marks of their footsteps, since, when the ostrich comes and
    finds that her nest is discovered, she crushes the whole brood,
    and builds a nest elsewhere." In Job 39:13 this word in the
    Authorized Version is the rendering of a Hebrew word (notsah)
    which means "feathers," as in the Revised Version. In the same
    verse the word "peacocks" of the Authorized Version is the
    rendering of the Hebrew pl. renanim, properly meaning
    "ostriches," as in the Revised Version. (See OWL [1].)
