I feel particularly baffled because, compared to many zoos, Twycross seems to have a fair amount of open space which (from a layperson's POV) could potentially be used to erect better housing. I like the space, and the trees, but consider animal welfare to be more important. Have also read (though can't state this with authority obviously) that Twycross are sitting on quite a considerable reserve of funds. How better to use (some of) that to build accommodation for the chimps which'd enable them to live in a more natural group ? 'The World Primate Centre' should earn its title, not just by the variety of primates it keeps, but also from the quality of its care for them.
