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.

there are two birds in the process of this: the house finch and the brown-headed cowbird. the house finch is the one that built the nest and laid the blue eggs. however, that speckled egg was laid by the cowbird. the cowbird does this to use finches to raise their own children, not really regarding the harm caused to the baby finches.

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.
