Description

Canivet's emerald grows to a length of 8 cm (3.1 in) and weighs 2.3–2.5 g (0.081–0.088 oz).[3][4] The male is metallic green with a forked blue-black tail. The female is green above and grey below, with a dark eye mask topped by a white stripe behind the eye. They are virtually identical to the garden emerald, with the exception of bill colour; Garden has an entirely black bill while Canivet's has a red-based bill with a black tip. The two species have no overlap in their ranges.

Taxonomy

The subspecies C. c. salvini, which occupies the southern part of the range from extreme south of Mexico to Costa Rica, is sometimes split as Salvin's emerald.
