Do you know if all those birds are Mourning Dove, or a mix of other dove species?
We have Mourning, White-wing (migrate to and from Mexico), Inca, Eurasian Collared, Rock (pigeon). We have a rather famous dove hunting season here. The Inca are too small to be game. Mourning and White-wing are the most popular game birds. The Eurasion Collared is considered an invasive species and there is a no-bag limit on those, meaning take all you can get. They are big for dove also. I don't know about the quality of the meat though, never had the opportunity to try it.
I'm glad the Inca are too small to hunt, they are so beautiful to me. I feed the neighborhood dove in my yard. They absolutely love cooked rice for whatever reason.
