I find doves to be one of the easiest birds to pluck. You can also skin them if you don't like plucking them, but they pluck so easily that it only takes perhaps 30 seconds and you have a clean whole bird with the skin on which I think helps keep them moist during cooking.
My 2 favorite ways to prepare them both involve bacon,,,,, of course :)
#1 fry up a good portion of bacon then leave the grease in the pan. split the doves in half, season with whatever seasoning you like and simply fry them in the grease quickly on both sides. You can coat them in a light dusting of flour prior to frying if you like.
#2 season the whole bird,,,, wrap a couple of strips of bacon around the bird, broil quickly until golden brown,,,,, serve up and eat.
Actually I thought of another way too.......... wrap birds in bacon and place them on the very top level of your barbeque grill. Put the grill flame on low to medium and place some mesquite wood or hickory wood in one of those metal boxes designed to hold the wood/chips and place the box on the coals. If you don't have one of those smoking boxes you can simply put a supply of chips or dust inside some heavy aluminum foil, poke some holes in the foil and place foil on coals. Let the birds cook slowly until they are nicely browned. mmmm mmmm good.....
And yes,,,,,, I will feely admit that my love affair with bacon continues :)
