I'm reliably advised that it was in fact the pigs and Crab-eating Macaques that did the most damage. Just goes to show, you can try to add order by calling it a Crab-eating Macaque, but it will do exactly as it pleases anyway.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
