The Gray-breasted Bristle-cuckoo is a small bird from the cuckoo family. It lives in Southeast Asia and is known for not building its own nests, but laying eggs in the nests of other birds.
The Gray-breasted Bristle-cuckoo differs from other cuckoos with its gray breast color and distinctive voice. It is important for nature because it eats many harmful insects and serves as an example of brood parasitism.
