Buteogallus milleri is an extinct species of buteonine hawk. The only remains discovered—a fragmentary coracoid (the holotype) and the distal half of a humerus—are from Hawver Cave in El Dorado County, California. B. milleri was larger than Buteogallus fragilis or Geranoaetus melanoleucus (the black-chested buzzard-eagle), and close in size to the Cuban species Buteogallus borrasi. However, there is not yet enough material to fully assess the similarities between B. milleri and B. borrasi.[1] [2] B. milleri is named after paleontologist Loye Miller.
