In summary, I'm definitely not suggesting zoos ever should keep elephants in small enclosures; even the smallest documented natural home range far exceeds the largest elephant enclosure (on this single parameter elephants actually aren't all that different from most other animals kept in captivity, e.g. carnivorans). Their complex social structures also make satisfactory elephant keeping particularly complicated. Indeed, I am very happy that new spacious elephant enclosures with features aimed at enrichment seem to be opening with some regularity. However, I am suggesting that claims made by certain anti-zoo groups ("elephants need to walk 10s of miles a day to live a decent life" and alike) should be taken with a grain of salt.
I agree. Releasing Morgan would be a death sentence to her.
However, I am of the opinion that she should be moved to a different park, Marineland France to be exact. With a proper adult matriarch and a stable social structure, Morgan would find life to be much better as opposed to the somewhat chaotic social structure at Loro Parque. Additionally the two mature males there are fairly poorly represented in the captive gene pool and would be ideal mates for morgan.
Her deafness might be due to trauma. She wasn't a young calf when she get separated from her pod, she was at least three years old, so she managed to keep up with her mother's pod somehow.
I don't know nearly enough about killer whales though. Perhaps her family were keeping a close eye on her for her first few years but as she got older she became more independent and wandered off, and could not find them again.
She's still very young though. There are several years left before she should be mating if she is going to be used for breeding. Plenty of time for genetic tests.
Do we know where her exact family is? If we did then release might be possible.
Trying to foist her on any other group (which is how Stumpy survives) probably won't work.
Stumpy can find new groups when she gets lost or abandoned, Morgan would get left all alone.
Her getting separated in the first place probably wasn't the result of anything dramatic. She likely wandered off and then simply couldn't find the rest of her family. They might not have understood that she was deaf.
