The melodious blackbird (Dives dives) communicates with the other birds via a song that is a duet between the pairs, followed by a whit and a whistle. A resident breeder from coastal eastern and southeastern Mexico to Costa Rica, the male and female look identical with plumage that is wholly black with a slight velvety sheen. The scientific name dives dives comes from the Latin meaning “costly or rich”, probably because of its very shiny look.
