The steely-vented hummingbird (Amazilia saucerottei) is a medium-sized hummingbird that is a resident breeder from western Nicaragua to Costa Rica, and also in Colombia and northwestern Venezuela. The Central American birds differ in voice and behaviour from those in South America and may be a separate species, the blue-vented hummingbird (A. hoffmanni, syn. A. sophiae). Both forms are sometimes placed in the genus Saucerottia, but this is not recognized by most authorities, notably AOU and Howard & Moore.
