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.
One of the only birds that lay blue eggs are Blue Jays, they do not usually lay them on the ground though. There is a very good chance it fell out of a nest.
A robin lays a small blue round egg. If you have found one on the ground don't pick it up because then the robin won't take care of it. It's important to remember that birds can smell human scent!
The Cuckoo bird -- well, actually the cuckoo doesn't "steal" the nest, the female just lays her egg there and let's the original nest owners raise HER young. The Black-headed Grosbeak -- is known to steal parts & pieces of another bird's nest to construct her own. But Sparrows steal nests from Martins, sometimes forcing Martin eggs or even young ones out, letting them fall to the ground. Starlings, in turn, steal nests from Sparrows. The Brown-headed Cowbird also lays its eggs in another's nest and leaves others to raise its young. A mourning dove has been observed taking over a newly built Robins nest.
The female Common Cuckoo lays her eggs in other birds nests, like the Reed Warblers and Willow Warblers nests.
Nightingale lays eggs in the Crow's Nest.
It is the cuckoo (Cuculus canorus) that is a parasitic layer of eggs in other bird's nests.
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.
A cuckoo doesn't make a nest of it's own. Instead it lays an egg in another birds nest. The cuckoo relies on the other (smaller) birds to raise it's young for it. Cuckoo birds lay their eggs in clocks. I thought everyone knew that. It is the Brown-headed Cowbird that lays their eggs in other birds' nests.
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.

No, but a cowbird lays eggs in the nests of other species, and that may be the case here.
The cuckoo bird lays its eggs in other bird`s nests and the mother will raise the resultant chick, even though it is of a different species. The young cuckoo will even push the other eggs out of the nest.
Cuckoos do this.
all birds lay eggs
other birds, such as ducks and geese.
