At Loro Parque dolphinaria.truth filmed a training session of Morgan with one of her trainers Julian, who ist one of the chief trainers and an expert for orca training. He trains her from the beginning and has a great relationship with the rescued killer whale. This video was filmed in the morning. Morgan already got her breakfast (a feeding of fish without training), spend some spare time and then took part in this training session. She performes spectacular jumps, which are behavioural enrichment for her and educate people about the intelligence and strength of orcas during the show.
You can also see Julian reinforceing positively waiting of her. Why? Professional trainers already knew in the 1960s that dolphins love to perform in training sessions or shows. Their motivation is therefore really high and they become short-temperedly. That’s why waiting is a behaviour that needs to be reinforced - it’s not easy to do for dolphins enjoying training sessions.
As you can see, Morgan could swim away easily. If she wouldn’t like this training, it would be no problem to leave Julian. She knows she would get the fish in a feeding later and would have no disadventage because of non participating in this session concerning her food. Morgan doesn’t leave, because she enjoys spending time with Julian. Relationship is the key and why dolphins take part in sessions like that.
