Violet-capped woodnymph
The violet-capped woodnymph is a species of hummingbird in the family Trochilidae. It is found in forest, dense woodland, gardens and parks in south-eastern Brazil, eastern Paraguay, Uruguay, and far north-eastern Argentina. It is widespread and generally common, and therefore considered to be of Least Concern by BirdLife International.Description
The male is distinctive, being overall green with a blue cap and deeply forked dark blue tail. It is occasionally confused with the swallow-tailed hummingbird. The female lacks the blue crown, has entirely greyish-white underparts, and a shorter, white-tipped tail.
