Nano Technology Enables Scientists to Study Migrations of Pied Cuckoo

  • To study migratory patterns of the Pied Cuckoo, a number of agencies are using advancement in nanotechnology.

  • Pied Cuckoo is a bird closely linked with the arrival of the Southwest monsoon in India.

  • The project is a joint effort by the

    • Wildlife Institute of India (WII), Dehradun

    • The Indian Institute of Remote Sensing (IIRS)

  • IIRS comes under the Indian Space Research Organization (ISRO).

Overview

  • There are three subspecies of Pied Cuckoo

    • One is resident in Africa

    • One in South India

    • Third is migrant between India and Africa

  • As the bird is small and terrestrial, crossing the sea holds a lot of risk for cuckoo.

  • While migrating back home in the southern African region, by flying over the Arabian Sea, and the Indian Ocean, it must be having stoppages.

  • The agencies want to find out these stopovers.

  • The scientists also want to find out how birds respond to climatic variations in the long term.

  • The pied cuckoo is famous in North India folklore as ‘Chatak’.

  • Chatak is a bird that quenches its thirst only with raindrops.

  • It is a brood parasite.

  • A brood parasite does not make its own nest and instead lays its egg in the nest of other birds, particularly the Jungle Babbler.

  • Adult Cuckoos weigh 65 to 75 grams and so any tracking device to be put on them needs to be very small. The thumb rule is that it has to be less than 3 percent of the body weight.
