Western Marsh Harrier/වගුරු බිම් උකුස්සා/වගුරු හැරිකුස්සා (Circus aeruginosus)

An uncommon winter migrant to marshes, grasslands, and paddy fields throughout the country, mainly in the lowlands. It is usually encountered as a solitary bird and feeds on frogs, water snakes, fish, and water birds such as teals and waterhens, as well as small mammals and insects including grasshoppers. It hunts with a slow, sailing flight close to the ground. Like other harriers, it often perches on the ground and probably roosts there at night, though it also frequently perches in trees.  The Western Marsh Harrier breeds in Europe and Asia, north of the Himalayas.
