sapphire-bellied hummingbird Chrysuronia lilliae

Rare, endangered, and poorly known hummingbird restricted to mangroves and adjacent scrubby areas along the Colombian coast. Male has sapphire underparts extending from throat all the way to belly, and lacks the distinct hood typical of the more common Sapphire-throated Hummingbird. Female’s plumage is not known with certainty, but likely resembles female Sapphire-throated Hummingbird, which has white central underparts bordered by green flanks, and white tail tips.
