The correct answer is Koel.

Concept:

  • Birds build nests to lay their eggs and incubate their younger ones.
  • Not all birds build nests eg. Koel lays its egg in the nest of a crow.
  • Different birds build nests at different places, some on ground level, some high up on the tree.
  • Different birds use different techniques and different materials to build their nests.

Explanation:

  • The crow builds its nest high up on a tree with all kinds of materials
  • The koel lay their eggs in crow nests.
  • This ensures that there's a higher chance of clutch formation. (The clutch is the number of eggs laid).
  • The koel's eggs resemble those of the crow in pattern and colour, which helps them in nesting.

Additional Information 

  • The dove makes its nest among the thorns of a cactus plant or a Mehendi hedge
  • The sparrow and pigeon make their nest anywhere on top of a cupboard, behind a mirror, on a ledge.
  • The barbet or coppersmith bird makes its nest in a hole, in a tree trunk.
  • The tailorbird uses its sharp beak to make its nest by stitching together two leaves on a bush. It lays its eggs in the fold of the leaf that it has made.
  • The sunbird makes a nest that hangs from the branch of a small tree or a bush.
  • The robin makes its nest with  soft twigs, roots, wool, hair and cottonwool at ground level, lower branches of a tree or sometimes at the top
