Which Bird is a Brood Parasite and Lays Its Eggs

Question

Which bird is a brood parasite and lays its eggs in the nests of other birds?  
A) Catbird
B) Cowbird
C) Magpie
D) Kirtland warbler
E) Blue jay

Accepted Answer

Cowbirds are well-known for being brood parasites, which means that they lay their eggs in the nests of other bird species and rely on those birds to raise their young. The other bird species will then unwittingly take care of the cowbird's young, often at the expense of their own eggs or fledglings. The other bird species is known as the host species.
