Honestly it is the whole killer whale/cetacean captivity can of worms that is on my mind with this. From what I've read a lot of people are not happy with the birth at Loro Parque (or in fact Morgan being there). But while I have mixed feelings about cetacean/killer whale captivity and am at the moment not sure anymore what my opinion on that should be, I am definitely not going to add to the choir of criticism and hatred towards these institutions. Do I have some critical questions, sure. But I'm not going to viciously attack people and places. I give Loro Parque the benefit of the doubt for now.
Most cetaceans, even the "common" bottlenose dolphins to some extent, probably will always remain very challenging species to suitably keep, care for and breed - and that definitely goes for killer whales.
Many facilities have already ended the breeding of killer whales and that won't make things easier I guess.
That said, it does seem to me that at Loro Parque they know what they're doing and are able to do things reasonably okay when it comes to killer whales. I'm sure they'll try everything they can.
