The Antillean Mango Hummingbird is found in the Dominican Republic, Haiti, Puerto Rico, the British and U.S. Virgin Islands.
It lives mostly in the subtropical or tropical dry forests and subtropical or tropical moist lowland forests.
The Antillean Mango hummingbird was once quite abundant in the Virgin Islands but now may only remain on St. Thomas and some of the British Virgin Islands. It is still common in the coastal plain of Puerto Rico.
It is thought that the Antillean Mango hummingbird is declining in numbers due to the Green-Throated Carib hummingbird which competes with it and has expanded its range into areas once inhabited by the Antillean Mango hummingbird.
The male Antillean Mango hummingbird has green on it’s back and head and has an iridescent green gorget. It has gray on its abdomen.
The female Antillean Mango hummingbird is green on her back and upper body and is grayish white underneath.
Their outer tail feathers are mostly brownish grey or chestnut colored.
