Only on Cozumel Island, Mexico, where it is usually the most frequently encountered hummingbird. Feeds low to high on a variety of flowers, preferring forest edge, gardens, and other semi-open habitats. Male is stunning, emerald-green with a long, deeply forked tail. Female has distinctive broad dark facemask, rather long forked tail. No similar species on the island (Canivet’s Emerald occurs on the Yucatan mainland).
