A greenish brown color with many dark speckles.
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.

Bay-winged Cowbird was created in 1819.
In this interaction, the cowbird has deposited its eggs in the sparrow's nest, leading the sparrow to unknowingly raise the cowbird chick along with its own. This is an example of brood parasitism, where the parasitic bird relies on others to raise its young. It can negatively impact the host species by diverting resources away from their own offspring.
The Cowbird wouldn't have any food or protection from pests.

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
The color of the greenish egg white is pale green.
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.
