Ostrich, n. A large bird to which (for its sins, doubtless) nature has denied that hinder toe in which so many pious naturalists have seen a conspicuous evidence of design. The absence of a good working pair of wings is no defect, for, as has been ingeniously pointed out, the ostrich does not fly.
2005 Update: The evolutionary successor to the owl as mascot for the fourth estate. Cultural naturalists debate whether the Ostrich itself will soon suffer the fate of it's predecessor, replaced by a really cute caged songbird. Or a plump turkey with a blogger account.
