The cowbirds remove ticks from the bison, while the bison disturb insects that are picked up by the birds.
No, but a cowbird lays eggs in the nests of other species, and that may be the case here.
I believe some species of birds steal others birds eggs and raise them as their own but I suggest you look up purple finches on the internet or a book and read about them laying eggs to be sure. I've never heard of birds stealing other eggs and brooding them but what I do know for sure is that the Brown Headed Cowbird does not make it's own nest and lays its eggs in other birds nests. The Cowbird is actually considered a parasite in that it's eggs will hatch first and dominate the nest. In some circumstances some of the intended hatchlings could starve to death or be killed by the young Cowbirds. Simply remove the brown spotted eggs.

Birds that are useful to humans could be they type we use for food such as chickens which provide eggs and meat. They type that provide feathers for quilts such as geese. Hawks and other raptors that catch and eat mice and rats in the fields. Or the every day backyard birds that eat insect pests in the garden.
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.
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.

The famous cuckoo and the screaming cowbird.
AnswerBison horns curve inward and point at each other. Buffalo horns curve outward. Bull bison horns NEVER point towards each other, only the cow (female) ones do. The words buffalo and Bison (which both literaly translate to "Ox like animal") can both refer to the American Plains Bison (Bison bison bison) and the American Woods Bison (Bison bison athabascae- which is larger). Both species have similar horns. Water buffalo horns are much different.
Any of various blackbirds of the genus Molothrus,especially the common North American species that lay their eggs in the nests of other birds and are often seen accompanying herds of grazing cattle.
