Size relative to a 6-ft (2-m) 
Hesperornis was a large, flightless seabird, up to about five feet tall. Although it was incapable of flight, 

Hesperornis was a swift swimmer that could propel itself through the shallow coastal waters of the Pierre Sea with its powerful hind legs and webbed feet.  It’s webbed feet were similar to a grebe.  It’s jaws were equipped with sharp, pointed teeth adapted for preying on fish and squids.
