Delivering Items via Messenger Ravens

Add ravens, perhaps the smartest bird in the world, with some behaviors to teach us about them. Add functionality where you can attach a bundle to them and give them seeds or berries, they then can fly to a player of your choice in a poof of black feathers. It appears near the other player, and once they have the bundle, it returns to you. Ravens are also very acrobatic in the air in the real world, and therefore could add a lot more life to Minecraft's skies. Players want more birds, and this would also allow them to deliver resources to friends such as food for their journey, fresh tools, or even obsidian to make a portal to get home. Ravens are also very Gothic, and sitting them down in a build can add a lot of life and character.
