injured duck/breed identification?

I would suggest that try to find a Wildlife rehabilitator to take care of the duck, if it is wild, and just because she behaves calmly does not mean she is a pet. Some wild ducks can be very tame if they have never been around people or have had significant exposure to humans. If she was a pet, legally she should have a leg band or one of her hind toes cut off. If she still has both hind toes and no band she is more than likely wild. A number of wild ducks have rather finicky diets and rehab center would likely know how to take care of her. As to where she was found, I know that sometimes duck and other waterfowl will land on pavement if it is wet because it can look like a pond. Her bill is the right shape for a Ruddy Duck and the injuries are likely sustained from hitting the black top. As far as I know ruddy ducks are also federally protected so you must have the proper permits to keep them. I think a wildlife rehabilitation center would be the best place to take her since they are likely to be familiar with treating wild species.
