a bird
Yes, the cowbird is a brood parasite that lays its eggs in the nests of other bird species. The host birds unknowingly raise the cowbird chicks as their own, often at the expense of their own offspring.
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.
cowbird
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.
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 cowbird and the bison do have a few disadvantages in their relationship. Although the bison probably cannot feel it, the cowbird might be annoying with all the pecking and flocking around. The cowbird might get trampled if the bison decide to stampede.
