The redback fisherman ( Ceyx rufidorsa ) is a Southeast Asian kingfisher.

features

The red-backed fisherman reaches a body length of 12.5 to 14.5 cm. The plumage is yellow-orange on the underside. The mantle and wings are reddish with a purple tinge. There are white spots on the chin and the ear covers. The beak and legs are red.

Occurrence

The bird lives up to a height of 455 m on streams, ponds and other small bodies of water in lowland rainforests and sometimes in the mangroves . It occurs in Thailand , Malaysia , Indonesia , the Philippines and rarely in India .

food

The food the bird hunts from a perch consists of fish, crustaceans, insects and other invertebrates.

Systematics

Some experts regard the redback fisherman only as a color variation of the jungle fisherman ( Ceyx erithacus erithacus ). In contrast to the redback fisherman, the jungle fisherman has a dark blue to black top. On Borneo , where both kingfishers occur together, they mate with each other and there are all gradations between the red-purple and the black-blue upper side. There are also intermediate forms on Sumatra and the Malay Peninsula .

North of Kuala Lumpur , however, the redback fisherman is sedentary, while the jungle fisherman goes on migrations. Here they rarely mate with each other and otherwise behave like two different species.
