I have just visited Twycross, Gibbon forest is looking good but I have just had a thought what is there to stop a bird of prey i.e. a Buzzard from taking a young gibbon and what is there to stop them from getting off the island ?
Plus buzzards are usually scavengers.
many gibbons on the moors?They'll take carrion if they can get it, certainly, but they are primarily hunters - see them hunting on the moorlands next to Helly's house regularly.
Paignton had some metal screening over an enclosure (prairie dogs?) to stop gulls attacking youngsters.
No it was put up to stop the Birds used in the Flying Displays the zoo does from making a mistake and landing it and ending their display careers a little early!!!The lion enclosure at colchester zoo has bird protection but that is to stop the birds from flying in with the lionslike what happened a few years ago.
