Favors evergreen forest and edge in tropical lowlands, often near streams. Feeds mainly at low to middle levels in shady understory, but comes to feeders at edges and in clearings. Male is stunning but often looks all dark: note the fairly long, deeply forked tail and brilliant emerald and violet plumage. Female rather dull and plain: note the black bill, green-mottled flanks, and blue-black tail with whitish corners.
