What has a symbiotic relationship with a cardinal?
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.

No. One bird is a brood parasite. It lays eggs in the nests of other birds. Its babies are larger and more aggressive, so the other bird's babies die. If you are in North America, the brood parasite was a Brown-headed Cowbird, and the eggs were tan and speckled.

Found a purple finch nest in our blue spruce when you checked the nest for eggs you found eight eggs five were very small and solid light blue the other three were a pale green with brown spots?
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.
