It gets them away from the burden of raising the chick.
The offspring survives at less effort from the parent(s).
For a bird, that's a win.
Evolution.
They aren't the only birds to do it either - one species of duck even does it.
The brown-headed cowbird does it also.
Nightingale lays eggs in the Crow's Nest.
Female cuckoos lay their eggs in the nests of other birds, which then raise the cuckoo chick as their own.
Common cuckoos do not build their own nests or incubate their eggs. Instead, they lay their eggs in the nests of other bird species and rely on the host bird to incubate the eggs and raise the cuckoo chick.
Cuckoos and cowbirds lay their eggs in other birds' nests, and leave them for the other bird to raise. Weavers and whydahs (African species) also do this.
The cuckoo is the bird which never builds nest. Cuckoos lay their eggs in the nests of other birds and leave the "adopted parents" to raise the cuckoos own chicks.
Cuckoos are known for their brood parasitism, where they lay their eggs in the nests of other bird species. The female cuckoo typically observes potential host nests, waits for the host to leave, and then deposits one of her eggs, often removing one of the host's eggs to reduce detection. Cuckoo eggs often mimic the size, shape, and color of the host's eggs, increasing the chances that the host will care for the cuckoo chick once it hatches. This strategy allows cuckoo chicks to benefit from the care and resources of other birds.
Usually - it would be called a 'nest'. However - cuckoos don't build their own nest to incubate their eggs - they lay their eggs in the nests of other birds - for the 'foster mother' to incubate the eggs instead.

Yes, starlings are known to lay their eggs in other birds' nests, a behavior known as brood parasitism.
No. Some birds nest on the ground (curlews), some (woodpeckers) make holes in trees and some lay their eggs in other birds nests (cuckoos).
cow birds lay there eggs in other bird's nests.
