Answer 1

1) Answer: In the nests of wide range of other species of birds (brood parasites)

Cuckoo birds are brood parasites meaning, they lay their eggs in the nest of other species of birds (eg; crows). They lay camouflaged eggs in the nest of other birds along with the egg of that bird and those birds raise the eggs of cuckoo bird along with their own eggs thinking that it is their egg. Thats why it is refered to as brood parasitism.

Cuckoo bird donot build any kind of nests.
