Description General Info
Description
This is the largest Rallina, measuring about 34 cm in length. It has a glossy chestnut plumage, extensive bold barring on underparts, unbarred undertail-coverts, relatively bright apple-green bill and relatively long and fluffy tail; legs and feet are olive-green. It also has pale barring on wings confined to outer primaries and greater and medium coverts. Juveniles are duller and less prominently barred. Other similar looking crakes include other Rallina and ruddy-breasted crake Porzana fusca. They are smaller and do not have green bill and legs. Immature birds are duller overall with the barred areas being dark grey-brown with a chestnut tinge, narrowly banded and streaked dirty white. Juvenile birds are paler than adult. Voice is a deep croak. It utters a sharp click as an alarm call.

Feeding Habits
Andaman Crake consumes a varied diet including small fish, molluscs, worms, and a range of insects like beetles, grasshoppers, and caterpillars. It exhibits unique behaviors, such as vigorously shaking and battering large grasshoppers prior to consumption.
Habitat
The andaman Crake predominantly inhabits marshlands within forested regions, thriving in large, open marsh areas. It is also known to reside in smaller marshes situated on the peripheries of secondary forests. These environments are characterized by wetlands with aquatic vegetation, which provide shelter and feeding grounds for the species.
Dite type
Omnivorous
General Info
Distribution Area
Its natural habitat is marshland inside subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests. It is threatened by habitat loss. It is known from North, Middle and South Andaman islands and may occur on other islands such as Great Coco or middle Coco Islands. It was formerly classified as data deficient by the IUCN, due to the lack of reliable information on its status. Later studies showed it to be fairly common in suitable habitat. Consequently, it has been listed at least concern status in 2017. BirdLife International estimates the population to range between 10,000 and 25,000 individuals.
Species Status
In the 1980s, the crake was considered to be quite common on the islands; over 80 birds were snared in a square mile. It is much rare now even though there are extensive forests in the islands. Introduced predators may also pose a risk to the birds' population.
