This day my guide, Julián, took me to a garden on the edge of the Iguazú National Park where hummingbirds were being fed. Several species appeared, including this 'Versicoloured emerald' (many hummingbirds have strange names...). This hummingbird is common and occurs in various environments, such as forest edges, mangrove swamps, deserts and urban areas, in large parts of northern and eastern South America. This national park in northern Argentina is one of the southernmost reaches of its range. The species is divided into two subspecies, a coastal one with a white bib and an inland variety without a bib. The bird is 8–10 cm (3–4 in) long and has a long, slightly curved bill, the lower part of which in some individuals can be bone-colored or even orange (something you can make out in the photo with a little good will).
