BHARATPUR: Nepal is a seasonal home to species of migratory birds for incubation, said a survey and observation based on the Chitwan National Park and adjoining community forests.

Tentatively, female migratory birds from India, Sri Lanka, and other South Asian countries come to Nepal since February/March for laying eggs and hatching,

The incubation period is normally of one and a half months to two months.

Such birds have chosen grassy lands and trees as their seasonal shelters. They have built nests in such areas and more nests have been spotted in the CNP and community forests adjacent to it.

Besides Chitwan, in this season, Parsa and Bardiya National Parks also welcome the migratory birds arriving for the purpose of incubation.  The highest inflow is recorded at the CNP and the census of seasonal birds is conducted only at the CNP.

The census has been in effect for five years and it is supported by Bird Education Society, Himalayan Nature, Nepal Ornithologists Association  and CNP.

So far, 887 species of birds are recorded in Nepal and according to experts, eight species of birds have vanished. The bird -spiny babbler- is found only in Nepal.
