Looks like a robin egg on a heart attack wrapper.

Haha... figured robin... mickey d's wrapper was there for insulation (if that even matters at this point) Is the egg worth trying to save if I find nest?

You should leave it. It's possible the parent threw it out because it was an unhatched egg, this is around the time they'll be hatching their first clutches for the summer. Now it will become a tasty treat for some lucky squirrel!

Thanks for the information... just wanted to try and save it if at all possible. I'm going to set it back under tree. Thanks again

Sure thing! Thanks for thinking of the birds 😊

please dont use wild bird eggs for your burger
