Boris - Bennett's Wallaby (Macropus rufogriseus)
At five years old, Boris is our oldest wallaby. Naturally, he has taken on the role of alpha male of our wallaby group - otherwise called a "mob". Essentially, this makes him the leader; the other wallabies will look to him if they sense danger, to see how he reacts. If his reaction is to evade, they will do the same. Boris' role as alpha also gives him preferential access to the females. Or maybe his exotic accent won them over - he is from Prague after all...
Boris is the mate of Lilly. He will stick close to her and show his dominance when he feels necessary. If he catches Darren (our other male) trying to court his mate, he will shoo him off with foot thumping and hissing.
