Bird Question. Do birds adopt eggs?

Yes they do...almost any bird will do it...

I raise exotice birds and if a bird I know is NOT a good parent to their chick when it hatches, I remove it and put it with a better parent...I have one Cockatiel that does this all the time...she is a wonderful parent and has fostered many babies for me.!!!

No, that is a parasitical birds egg. Cuckoos do this. Cowbirds do this, though they dump the original eggs. A parasitical bird lays eggs in another type birds nest and the the bird who's nest it is raises the parasites young. Some species will wait until hatching to dump the original eggs, or kill the original nestlings,.

Go to top ten and ask Bird Girl for an identification of the egg.

I think Indigo is right. I just got an ID at " Cow Bird egg " in my address bar and it looks like a match. This seems a variation on usual Cow Bird dumping behavior, though.

This does look like a cowbird egg..however it looks quite large, but I am unable to tell the size of the other eggs as I have no size reference in the photo. The Yellow-billed Cuckoo also occasionally will lay it's eggs in other birds nests, but they are not as abundant as cowbirds which range widely across the U.S. ....so I would say this is most likely a cowbird egg. The cowbird will hatch first, grow quickly out competing the host chicks, and the host chicks will most likely die. If the nest belongs to a bird that is about the same size as the cowbird, the host chicks, or at least one of the host chicks may survive. Most birds parasitzed by cowbirds end up raising only the cowbird. I study an endangered bird species who commonly have cowbirds eggs in their nest which has contributed to their decline..I am licensed to remove those eggs from the nest to give the endangered birds a chance to survive.

Idk if Birds Do That Or Not. I Think One Kind Of bird Lays Its Eggs In Other Nests But I dunno...

And I Cant tell What The Big Egg Is But The Little Ones Look Like Blue Jays.

That large egg is from a Cuckoo. When the eggs hatch the Cuckoo chick will push the others out of the nest. The mother, thinking that it is hers will continue to raise the Cuckoo.

You can call it "adoption" if you like, but what basically happens is that you get birds like cuckoos that will lay their eggs in another birds nest, which will then be hatched and reared by the "adopting" parents.

"The Brown-headed Cowbird (Molothrus ater or BHCO) and Bronzed Cowbird (Molothrus aeneus) are the only obligate brood parasites in North America. These birds don't build their own nests. Instead, they lay eggs in the nests of other birds, depending on the surrogate parent to incubate their eggs and rear their nestlings." http://www.sialis.org/cowbirds.htm (with photos)

It's probably a cowbird egg. (I'm not sure though, exotic birds are more my forte.)

There are species of bird who will lay their eggs in other species nests, their babies are larger and sort of take over the nest, often the other babies die off because the invader species ' baby gets more of the food.
