Task: Question Answering
Input (English): passage: Rooks are distinguished from similar members of the crow family by the bare grey-white skin around the base of the adult's bill in front of the eyes. The feathering around the legs also looks shaggier and laxer than the congeneric carrion crow. The juvenile is superficially more similar to the crow because it lacks the bare patch at the base of the bill, but it has a thinner bill and loses the facial feathers after about six months. Collective nouns for rooks include building, parliament, clamour and storytelling. Their colonial nesting behaviour gave rise to the term rookery.
 question: is a rook the same as a crow?
Output (English): No
