Yes it does
The Cowbird never has its own nest - it uses the finch nest as its host (read: parasite.) The Cowbird egg will hatch first & will push the other eggs or baby finches out of the nest. Other species of birds will get rid of the Cowbird eggs, but finches don't seem to. I always remove them when found.
It's not symbiotic, it's parasitic. The cowbird lays it's eggs in the nest of other birds expecting them to hatch and feed it. In some cases when the host bird rejects the egg the cowbird has been known to return to the nest and ransack it in what scientists call Mafia behavior.
the cuckoo is known to rid a nest of eggs, and lay their own eggs in the nest. Then they leave the original nest owner to raise their young for them.
Scientifically it's called "brood parasitism". The most well-known example of this type of birds is the Common Cuckoo. This is also the origin of the words "cuckold" and "cuckoldry".
The northern cardinal and the brown-headed cowbird have a symbiotic relationship. The brown-headed cowbird lays its eggs in the cardinal's nest (and in the nests of other species, too, such as the yellow warbler). This harms the cardinal's chances to reproduce. It's a parasitic relationship.

The famous cuckoo and the screaming cowbird.
A cuckoo doesn't make a nest of it's own. Instead it lays an egg in another birds nest. The cuckoo relies on the other (smaller) birds to raise it's young for it. Cuckoo birds lay their eggs in clocks. I thought everyone knew that. It is the Brown-headed Cowbird that lays their eggs in other birds' nests.
Cowbirds. They lay their eggs in other birds' nests, creating a hazard for the chicks in the nest, because cowbird chicks are usually stronger than the birds in the nest they hatch in. The parents just try to feed them all and the cowbird gets the most attention.
The cow bird. The cow bird lays it's eggs in another birds nest, and then when the cow bird's eggs begin to hatch, the baby cow birds will push the other birds out of the nest.
Yes. The Brown Headed Cowbird lays its eggs in a different birds nest while the parents are away. So the mother bird of the nest thinks its their egg. She will raise it until it can fly away on its own.

Cuckoos do this.
The cuckoo!
I believe some species of birds steal others birds eggs and raise them as their own but I suggest you look up purple finches on the internet or a book and read about them laying eggs to be sure. I've never heard of birds stealing other eggs and brooding them but what I do know for sure is that the Brown Headed Cowbird does not make it's own nest and lays its eggs in other birds nests. The Cowbird is actually considered a parasite in that it's eggs will hatch first and dominate the nest. In some circumstances some of the intended hatchlings could starve to death or be killed by the young Cowbirds. Simply remove the brown spotted eggs.
