The swallow-tailed hummingbird (Eupetomena macroura) is a species in the hummingbird family (Trochilidae), found mainly in east-central South America. Most authorities place it in the monotypic genus Eupetomena, although some place it in Campylopterus based on song and the thick shafts of the males’ first primaries. Its common name and specific epithet (which means “large-tailed”) both refer to the long, deeply forked, somewhat swallow-like tail.

The majority of the range of the swallow-tailed hummingbird is in the Caatinga and Cerrado of Brazil, and adjacent parts of northern and eastern Bolivia, and far northern Paraguay. In the coastal regions, it occurs from French Guiana in north to Santa Catarina, Brazil, in south.

It generally avoids the rainforest found throughout most of the Amazon Basin, and only extends locally into this region along the southern and eastern edge, in the relatively open habitats along the lowermost sections of the Amazon River, including Marajó Island, and upstream to around the Tapajós River, and in isolated enclaves of woodland or savanna-like habitats within the Amazon (including so-called “Amazonian Caatinga”) in south-eastern Peru (upper Urubamba River and Pampas del Heath), southern Suriname (Sipaliwini savanna), central Brazil, and northern Bolivia.

It occurs in virtually any semi-open habitat; even gardens and parks within major cities[8] such as Rio de Janeiro and São Paulo. It avoids the interior of humid forest, but does occur in openings or along the edge; the swallow-tailed hummingbird is most common among savanna-like vegetation. It is generally a species of lowlands, but occurs locally up to 1,500 m (4,900 ft). Not a true migrant, some populations move north or south a short distance in the dry winter months.

Throughout the bulk of its range, it is among the commonest species of hummingbird, although it generally is uncommon in the outlying regions, particularly where it becomes more humid. In southern Brazil, it is apparently increasing and seems to have extended its range in recent decades. It is considered to be a Species of Least Concern by the IUCN. It was frequently exported for the cage bird trade up to 1970, but like other hummingbirds, it is nowadays on CITES Appendix II and trade is restricted. Also, hummingbirds are generally hard to keep in captivity, and though this species is generally rather hardy, it has been noted that abandoned young may die despite given optimal treatment when trying to hand-raise them. source
