"To lose one orangutan may be regarded as a misfortune, to lose both looks like carelessness"![]()
I've just had a look at the Twycross 'Orangutans' thread to confirm that a Zoochatter from Dvur Kralova says Dona was sent to Chester to pair up with Kevin from Berlin, rather than Sibu.
The problem there though was that no-one knew anything about Kevin. I think someone asked a keeper (might've been Bongorob) and the keeper didn't know about Kevin either.
The plan from the beginning with Sibu was to house him and try to bring in a compatible female before sending the pair of them away. Using this plan, the apparently sudden decrease from 2.4 to 1.3 seems to indicate that this happened.
However the Sibu death story popped up on here a few days ago and no-one has got any indication whether this is true or not (do we have a definitive source of the information for his "death"? I can't remember the post, even though i probably posted on it).
If Sibu did die, then perhaps the zoo sent Donna back as she was no longer required as his partner...
