There is also the David Sheldrick Wildlife Trust[3][4] which takes care of elephant and rhino orphans (most of them are orphans due to poaching). For $50 a year, you can become a sponsor of a particular orphan and they'll send you photos and updates about how your sponsored animal is doing. You can for example sponsor this little fella [5][6]. It's a great gift.
