An eastern grey kangaroo (macropus giganteus) licking her pouch and cleaning her joey. Note at 1:20 the female spreads her arms and leans forward. This is her cue for the joey to return to the pouch. This is usually accompanied by a clucking sound (which unfortunately I didn't catch on film). She doesn't let the joey in at other times because she is trying to teach it to come when called.
