You did good! What a beautiful bird! Is it a rock dove?
It doesn’t look limp or in shock to me...I’ll tell you that we had much success using canned food dog food on a recent mockingbird rescue.
I don’t know what kind of dove it is, but he’s really mellow about letting me put suff in his carrier. I have water, lettuce, carrot peel bits and apple bits, suggested by the lady at PetSmart. He is pretty, though.
