No, but a cowbird lays eggs in the nests of other species, and that may be the case here.

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.
Most likely, it is a bluejay. They are rather raucous talkers and are about the size of cardinals.
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.
What you saw was more likely a wren feeding a Brown-headed cowbird. Cowbirds are dark in color like crows but as adults are more blackbird-like in size. Cowbirds often lay their eggs in the nests of songbirds and allow them to hatch and raise the cowbird fledglings. This is a behavior known as brood parasitism and is normal for cowbirds. A cowbird fledgling oftentimes grows to become larger than the host parent that is raising it.
