I am in England. A while ago I saw on TV 2 African game wardens guarding a female rhino and her baby against poachers. She was habituated to them. One at least of them had an AK47 or similar in case of anything. From time to time he slapped the side of his AK47's receiver, making its mechanism rattle, as a "contact call" to keep contact with the rhino.
