Sorry, I didn't make myself clear. The wolves at Howletts are (as far as know) pure Iberian. There is no connection to Norfolk nor Wildwood (except both collections being in Kent). Howletts received the wolves possibly before the Norfolk transaction. I know the carnivore keepers (Howletts) were very keen on getting into the Iberian program. As somebody already mentioned the Aspinall zoos always look to species that nobody else is doing much with. I wouldn't necessarily agree with this direction... For example: interestingly it now makes for 3 pure populations of European wolf in the country (not withstanding the cross-breed Europeans and Canadian Timbers), as Highland have Scandinavians. None of which are working in the same direction.
From what I heard on the grapevine the wolves at Norfolk went to a private keeper (cannot think of name, North England?). He breeds alot of unusual species for the private pet trade (arctic foxes, genets, sugar gliders etc).
Before anybody asks I doubt that his intention with the wolves would be to breed for the private trade. One of the girls is quite old (an original founder at WW) while the other two were born in 2004/5 and the male is neutered.
What is going on at Norfolk is a whole other ballgame. I am surprised that they are still open.
