Birds of the Maldives

Birdlife on Coral Islands

The Maldives is not typically thought of as a birdwatching destination — the marine world takes centre stage. But for those who look up from the reef, the islands and surrounding ocean support a diverse community of resident and migratory birds. Over 180 species have been recorded in the Maldives, including seabirds, shorebirds, herons, and a number of land birds that have adapted to island life. For a country with so little land, this is a remarkable diversity.

Most visitors will notice birds without trying: grey herons standing motionless on the beach at dawn, white terns hovering above the reef, and crows calling from the palm trees. On less disturbed islands, particularly uninhabited islands and resort islands with mature vegetation, the birdlife can be surprisingly rich.

Herons

Herons are the most visible birds on Maldivian islands. The grey heron (Ardea cinerea) is a familiar sight on beaches and jetties, standing perfectly still before striking at fish with its long bill. They are remarkably tolerant of humans on resort islands, sometimes approaching outdoor restaurants to scavenge.

The striated heron (also called the green-backed heron) is smaller and more secretive, often seen crouching at the water's edge in harbours and along rocky shorelines. The black-crowned night heron is occasionally spotted roosting in mangroves and dense vegetation during the day, emerging to fish at dusk.

Terns

Terns are the seabirds you are most likely to see from a boat or beach. Several species are resident in the Maldives:

• White tern (fairy tern) — A strikingly beautiful, pure white bird with large dark eyes. White terns are common on resort islands with mature trees, where they nest on bare branches without building a nest — laying their single egg directly on a fork in the branch. Watching them hover is mesmerising.
• Sooty tern — Found in large colonies on uninhabited islands, particularly in the southern atolls. They are pelagic birds that spend most of their life over the open ocean, returning to land only to breed.
• Black-naped tern — A small, elegant tern commonly seen diving into lagoons for small fish. Identified by the thin black band across the back of its head.
• Greater crested tern — A larger tern with a distinctive yellow bill, often seen on sandbanks and harbour walls.

Frigate Birds

The great frigate bird (Fregata minor) is one of the most impressive birds in the Maldives — and one of the easiest to identify. With a wingspan of over two metres, a deeply forked tail, and effortless soaring flight, frigate birds are unmistakable overhead. Males have a distinctive red throat pouch that they inflate during breeding displays.

Frigate birds are kleptoparasites, meaning they often steal food from other seabirds in mid-air, chasing terns and boobies until they drop their catch. They are also skilled fishers in their own right, snatching fish and squid from the surface without landing on the water — their feathers are not waterproof, so they avoid getting wet. Look for them soaring high above the atolls, particularly near channels where fishing activity concentrates smaller birds.

Shorebirds and Waders

The Maldives sits on the Central Asian Flyway, a major migratory route for birds moving between breeding grounds in Central and Northern Asia and wintering areas in South Asia and Africa. During the migration seasons (September to November and March to May), a variety of waders and shorebirds stop over on Maldivian islands to rest and feed:

• Whimbrel — A large wading bird with a distinctive curved bill, commonly seen on mudflats and shorelines during migration.
• Common sandpiper — A small, active wader that bobs its tail constantly while walking along the waterline.
• Turnstone — A stocky shorebird that flips stones and shells to find invertebrates beneath. Often very approachable.
• Plovers — Several species of plover pass through, including the greater sand plover and the grey plover.

Land Birds

Several land bird species have become permanent residents of the Maldives:

• Asian koel — A cuckoo with a loud, repetitive call that is one of the most recognisable sounds on inhabited islands. Males are glossy black; females are spotted brown.
• White-breasted waterhen — A bold, ground-dwelling bird common in gardens and near freshwater areas on larger islands. It has a white face and breast with dark upper parts and a rusty-red patch under the tail.
• House crow — Introduced to the Maldives (probably from India or Sri Lanka), crows are now abundant on inhabited islands, particularly Male and Hulhumale. They are intelligent and noisy, and their growing population is a management concern on some islands.
• Indian myna — Another introduced species, commonly seen on inhabited islands foraging on the ground in small groups.

Where to See Birds

The best birdwatching in the Maldives is often on quieter, less developed islands. Uninhabited islands with mature vegetation support breeding colonies of terns and noddies. Resort islands with large gardens and minimal disturbance often have surprisingly good birdlife. The southern atolls, particularly Addu Atoll with its freshwater lakes and mangrove areas, offer habitats not found elsewhere in the Maldives and attract different species.

For marine birdlife, boat trips through atoll channels and visits to sandbanks often produce excellent sightings of terns, frigate birds, and occasionally boobies and shearwaters.
