Asian Koel

The Asian Koel  is a member of the cuckoo order of birds, the Cuculiformes. It is found in South Asia, China, and Southeast Asia. It forms a superspecies with the closely related Black-billed and Pacific Koels which are sometimes treated as subspecies. The Asian Koel is a brood parasite that lays its eggs in the nests of crows and other hosts, who raise its young. They are unusual among the cuckoos in being largely frugivorous as adults. The name koel is echoic in origin with several language variants and the bird is a widely used symbol in Indian poetry.
The Asian Koel is a bird of light woodland and cultivation. It is a mainly resident breeder in tropical southern Asia from India and Sri Lanka to south China and the Greater Sundas. They have great potential in colonizing new areas, and were among the pioneer birds to colonize the volcanic island of Krakatau. They first arrived in Singapore in the 1980s and became very common birds.Some populations may make long distance movements.
