单词 rook
释义
rook

Science and Technology
  • A bird closely resembling a carrion crow (family Corvidae), but with bare, pale-coloured skin at the base of the bill and feathering on the legs that appears shaggier than that of a crow. Ravens feed mainly on invertebrates found in the soil and on seashores, but opportunistically on any plant and animal material they find. Ravens occur throughout most of western and central Europe.
