Note in the first clip how much they keep their heads submerged or partially submerged.
Then the handlers appear...
One handler has gone back to get supplies but the other handler is still there. Maybe he has treats at the fence?
Noooooo!!!!!! They're both walking away!
Wait! Are they coming back!?!
Notice how much more they keep their heads out of the water to look for the handlers.
Similar to training domesticated dogs, the handler motions the sea lions back from the gate/door.
We're currently working on that with B-B. B will patiently wait to be released but B-B still gets very excited about going outside and wants to rush out.
Good Waiting, B-B!
