Dryolimnas cuvieri
The White-throated Rail (Dryolimnas cuvieri) is a medium-sized, highly secretive bird of the Rallidae family, measuring 25-30 cm in length and weighing approximately 145-220 grams. Its most distinctive field mark is a crisp white throat contrasting sharply with a grey head and neck, extending to the upper breast. The body plumage is predominantly rufous-brown, with darker upperparts and a paler belly. It possesses striking ruby-red eyes, a stout red bill, and long, reddish-pink legs and feet....
This rail primarily inhabits dense, often flooded, freshwater and brackish wetlands, including marshes, mangrove swamps, reedbeds, and coastal thickets, typically at low elevations.
The White-throated Rail is an opportunistic omnivore, feeding primarily on insects, small invertebrates (snails, worms), seeds, and various plant matter, foraging by probing in mud and gleaning from vegetation.
White-throated Rails are notoriously secretive and most active during the early morning and late afternoon, often remaining hidden within dense vegetation during the hottest parts of the day, though nocturnal activity can occur. Their foraging strategy involves probing in soft mud, gleaning insec...
The White-throated Rail's core distribution encompasses Madagascar and the Comoros archipelago, including Grande Comore, Anjouan, Mohéli, and Mayotte. A distinct subspecies, *Dryolimnas cuvieri aldabranus*, is resident only on the Aldabra Atoll in the Seychelles, making it a crucial site for the ...
Least Concern
- The Aldabra subspecies (Dryolimnas cuvieri aldabranus) is the only known living bird to have re-evolved flightlessness after an ancestral population colonized the atoll and became flightless, only to be wiped out by rising sea levels, and then recolonize and become flightless again. - It is the...
