While I assume you mean how fast can the bird fly, I'll include this snippet incase: SR-71 Blackbird set the world speed record in July 1976 of 2193.167 MPH and still holds it. The Bird Corvus corax or Raven, the best I am able to determine is about 14.3 miles per hour. The flight of birds is not an easy thing to accurately deduct.
14.3 mph

I think they can fly pretty fast.
humming birds fly so fast because they are so fast
A raven is a bird: a beaver is a mammal. Beavers live in and around water and do not fly, ravens fly and live in the air and in the tree tops. Ravens are omnivorous, beavers are herbivores.
