SECRETARY BIRD (Sagittarius serpentarius) - an extraordinary large, mostly terrestrial bird of prey. It is instantly recognizable as having an eagle-like body on crane-like legs which increases the bird’s height to around 1.3 m (4 ft) tall. This 140 cm (4.5 ft) long bird has an eagle-like head with a hooked bill, but has rounded wings. They can run so fast that they are sometimes referred to as "the devil's horse." They are excellent flyers, but they have a hard time getting off the ground.
