Ruddy kingfisher

The ruddy kingfisher ("Halcyon coromanda") is a medium-sized tree kingfisher, widely distributed in east and southeast Asia.
Description.
Reaching approximately 25 cm, the ruddy kingfisher has a very large, bright red bill and equally red legs. The body is rust red, generally deepening to purple at the tail. There is little sexual dimorphism though some sources report male birds being somewhat brighter in plumage. Due to its preference for heavily forested areas, the kingfisher's high, descending call is more often heard than the bird itself is seen, and these birds generally travel singly or in pairs.
Distribution and habitat.
The ruddy kingfisher ranges from South Korea and Japan in the north, south through the Philippines to the Sunda Islands, and west to China and India. It is migratory, with birds in the northern part of the range migrating as far south as Borneo during winter. Locally common in southern parts of its range, the ruddy kingfisher is rare in Japan, where it is highly sought after by birders. Ruddy kingfishers inhabit forested areas from the temperate to tropical zones, often in thick jungles and rainforests.
The binomial name recalls the Coromandel Coast of India.
