The Rufous tailed hummingbird (Amazilia tzacatl) is also known as Rieffer's Hummingbird. The vent and rump are rufous. The slightly forked tail is also rufous but with a dusky tip. The bill is almost straight, coloured red with a black tip. It can be be found in the open country, along river banks and the forest edge, in woodland and scrub, as well as plantations and gardens up to 1850 m (6000 ft), in Central and South America.
