Kendrapara, Sep 9: The annual census of monsoon birds has started at Bhitarkanika National Park, authorities said on Monday.
Birds throng the wetland sites for nesting in large numbers every year.
Four teams comprising ornithologists and wildlife personnel of the park are conducting the headcount of the avian species.
Each year during monsoon, a bird census is conducted to find out the current status of the bird species at the park.
Resident birds arrive at the park to lay eggs during monsoon while migratory birds arrive in winter from far-off places.
According to sources, the birds usually stay for three to four months and then embark on their homeward journey.
