Could they not do displays that demonstrate natural behaviour? Surely a show that educates and contains conservation messages is important? There are plenty of naturalistic behaviours to show - even feeding with a keeper talk would attract lots of visitors.
Don't they also have a Sea Lion show? Are they going to scrap that too?
I believe ideas are being mooted along those lines. The current format has been scrapped due to a combination of negative visitor feedback/criticism and the keepers being uncomfortable in portraying certain behaviours.
Sealions are the exception however-although behaviours like ball-balancing,flipper clapping are being removed. Personally, I think it's a fine line with the sealions.Youve essentially got an animal that's dog-like in its requirements and that thrives on interaction.
