LOL! They're pretty freaky little things. They are faily well known for their antiphonal calling - the males call a bit of a song and then the females will answer with the other half of the song. The males guard their mates pretty fiercely, and that's what makes them go a little loopy when they can see their reflection in thigs like windows, car mirrors and car windows. It's because males don't pair with females for a few years after they become sexually active and they will go and try and steal other males until they find a mate. Little birdy tom cats!
