Antigua and Barbuda’s islands combine limestone ridges, mangroves, coastal scrub and reef-lined shores, creating a variety of habitats for birds, reptiles and marine life. Small island ecosystems mean many species are adapted to very specific niches across the two main islands and nearby cays.
There are 44 Animals of Antigua and Barbuda, ranging from Antigua Bank Anole to Zenaida Dove. For each entry you’ll find Scientific name,IUCN status,Habitat & range listed so you can identify species and note conservation information — details you’ll find below.
Which species should I look for on a visit?
Start with common shorebirds and seabirds, then use the Scientific name,IUCN status,Habitat & range columns to target specific habitats; the IUCN status helps flag species of conservation concern and habitat notes point you to the best places and times to look.
How can I use the IUCN and habitat information for conservation or planning?
Treat the IUCN status as a quick risk indicator and the Habitat & range field as a practical guide to where species live; combine scientific names with local guides, protected-area maps and recent observations to plan visits or prioritize conservation actions.

Images and Descriptions

Magnificent Frigatebird
A dramatic large seabird with a forked tail and males’ inflatable red throat pouch. Common over Antigua’s coasts, they piratically steal food and loaf over harbors; easy to spot near nesting cays and mangroves.

Brown Pelican
Chunky coastal bird that dives for fish; brown adults common around Antigua’s bays and reefs. Often seen perching on pilings and beaches; locally valued and recovered from past declines.

Brown Booby
A plunge-diving seabird with a stubby yellow bill and dark body. Breeds on small offshore islands and cliffs; frequent around fishing boats and rocky shores in both islands’ waters.

Laughing Gull
A familiar coastal gull with a black hood in breeding season and raucous calls. Abundant on beaches and salt flats, scavenges at shorelines and around towns throughout Antigua and Barbuda.

Red-billed Tropicbird
Elegant white seabird with long tail streamers and bright red bill. Nests on remote cliffs and small islands; best seen on boat trips where they glide over open water.

West Indian Whistling-Duck
A long-necked, whistling duck that prefers mangroves and ponds. Locally uncommon but important for wetland health; watch for small flocks at protected ponds and salt marshes.

Bananaquit
A tiny, active nectar-feeding bird with curved bill and energetic calls. Very common in towns, gardens and scrub; often seen at flowering trees and feeders across both islands.

Zenaida Dove
A soft-toned, chunky dove with subtle patterns on wings. Common and tame around villages and dry scrub, often feeding on seeds on the ground and perching in low trees.

Caribbean Elaenia
A small, inconspicuous flycatcher with a soft call. Frequently found in coastal and inland scrub; look for it making short sallies from low perches to catch insects.

Antillean Mango
A medium-sized hummingbird with glossy plumage and fast-winged hovering. Common at nectar sources and fruiting trees; easy to see in gardens and coastal vegetation.

Brown Noddy
Dark-bodied tern relative that nests in large colonies on offshore islets. Often flies low over water looking for small fish; common on cays around Antigua and Barbuda.

Sooty Tern
A pelagic tern that breeds in dense colonies on isolated cays. Mostly seen offshore; follow boat trips to seabird colonies for the best views of hovering flocks.

Bridled Tern
A medium tern with distinctive facial markings. Nests on small islets and rocky shores; often seen flying low over waves or perched on rocks near nesting sites.

Osprey
A fish-eating raptor frequently seen hovering and plunging for prey. Scattered pairs hunt around Antigua’s bays and mangroves; conspicuous and easy to spot from shorelines.

Ruddy Turnstone
A compact shorebird that flips stones to find invertebrates. A regular migrant and winter visitor across Antigua’s rocky and sandy coasts; bold and active on shorelines.

Sanderling
Small, fast-moving sandpiper running at the water’s edge. Common migrant and winter visitor on Antigua’s beaches; watch flocks chasing waves foraging along the surf zone.

Willet
A large, long-legged shorebird with loud calls. Often seen probing mudflats and tidal pools; conspicuous on Antigua’s wetlands and coastal flats during migration and winter.

Semipalmated Sandpiper
Tiny migrant sandpiper forming flocks on mudflats and sandy spits. Common during migration seasons; useful indicator of healthy intertidal foraging areas.

Royal Tern
A large, crested tern with an orange bill that dives for fish. Frequently seen around Antigua’s coasts and offshore fishing grounds in sizable flocks.

Black-necked Stilt
Long-legged, distinctive shorebird with striking black-and-white plumage. Wades shallow salt ponds and lagoons; readily found in protected wetland areas on both islands.

Antiguan Racer
A tiny, shy snake once near extinction but recovering on protected islets. Endemic to Antigua Bank; notable conservation success after eradication of invasive rats on breeding cays.

Antigua Bank Anole
A medium anole with strong territorial behaviour; common on trees and walls. Active during the day, often seen around human habitation and coastal scrub habitats.

Common Garden Anole
A small, adaptable lizard that darts across walls and vegetation. Frequently seen in gardens and yards; males display colorful dewlaps during territorial displays.

Green Iguana
Large herbivorous lizard commonly introduced on Caribbean islands. Sometimes seen sunning on walls and trees; can be locally common where established.

Common House Gecko
Noisy nocturnal gecko often found on walls and lights hunting insects. Introduced and widespread; easy to spot at night around houses and streetlights.

Johnstone’s Whistling Frog
A tiny, terrestrial frog with a high-pitched whistle. Common around gardens and damp leaf litter; nonaquatic breeding makes it tolerant of island habitats.

Jamaican Fruit Bat
A medium fruit bat that feeds on fruit and pollen. Common in wooded areas and mangroves at night; plays important roles in seed dispersal.

Mexican Free-tailed Bat
Fast-flying insectivorous bat often detected at dusk. Roosts in crevices and buildings; common aerial hunter above fields and coastline after dark.

Small Indian Mongoose
Introduced predator established across many Caribbean islands. Hunts reptiles, birds and invertebrates; implicated in declines of ground-nesting birds and native reptiles.

Black Rat
A widespread introduced rodent that frequents settlements, docks and gardens. Common on both islands; important invasive species affecting native birds and reptiles.

House Mouse

Humpback Whale
Large migratory whale passing Antigua’s waters seasonally. Known for spectacular breaching and song; best seen on winter whale-watching cruises.

Sperm Whale
Deep-diving behemoth that feeds on squid. Occasional in Antigua’s deep waters; a special sighting for offshore wildlife tours and marine researchers.
