there are seven islands in total on this lake. The capuchins can use 3 of them (two are bridged by a log that can be seen on this photo, and I've also seen them jump to the smaller island at about 2 o'clock on the photo). Two islands are used by two species of spider monkeys (which cannot intermingle), and the remaining two are for red ruffed lemurs
the lake itself has a load of free-ranging waterfowl species: 2 species of pelicans, great cormorant, mute swans, common shelducks, ruddy shelducks, Philippine ducks, mallards, and perhaps others
