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.
This behavior is called brood parasitism, and it is seen in species like cuckoos and cowbirds. The female lays her eggs in the nest of another bird species, leaving them to be raised by the unsuspecting host. This frees up the parasite bird to lay more eggs elsewhere without the responsibility of parental care.
Cowbirds are known for practicing brood parasitism, where they lay their eggs in the nests of other bird species and let them raise their young. Once the cowbird chick hatches, it often outcompetes the host bird's chicks for food. This behavior can result in the host bird's chicks dying due to neglect or lack of resources.
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 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.
If a cowbird lays eggs in a flycatcher's nest, the best course of action is to leave the situation undisturbed, as many birds, including flycatchers, may not recognize the cowbird eggs as foreign. Interfering with the nest can lead to abandonment or harm to the remaining eggs or chicks. If the nest is in a location where it's safe to monitor, observe the parents' behavior to see if they continue to care for the nest. If concern for the flycatchers' welfare arises, contacting a local wildlife rehabilitation center for advice may be beneficial.
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 relationship is called parasitism because, 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 destroy it.Read more: What_is_the_symbiotic_relationship_between_brown_headed_cowbirds_and_other_birds
