Glittering-bellied emerald

The glittering-bellied emerald ("Chlorostilbon lucidus") is a species of hummingbird in the family Trochilidae. It has widely been listed by the scientific name "Chlorostilbon aureoventris", but this was shown to be mistaken by J. F. Pacheco and B. M. Whitney in 2006.
It is found in north-eastern Argentina, eastern and central Bolivia, eastern Brazil, Paraguay, and Uruguay. It is widespread and often common in a wide range of semi-open habitats, including gardens and parks.
