Large Falconine birds with strong hooked bills, toothed on all edges of 
mandibles, long wings, long tails, and strong legs and feet. 
In coloration and formation the species of RhyncJiodon agree with those 
of Falco, but are immensely superior in size. The birds have comparatively 
shorter tails, but comparatively longer, stronger legs and feet. Osteologists 
have found characters whereby to separate these generically. Superficially 
they might be regarded as subgenera.
