The Charming Birds of Matano Lake

Matano Lake, situated just miles northward of PT Vale processing plants, has a beautiful and attractive panorama. Nevertheless, the beauty of the lakeside's colorful birds are not known to many. A Vale engineer spares years of his free time to capture the beauty into a book.

Sulawesi is a paradise of biodiversity. Located amidst the imaginary line of Wallacea, that marks the biogeographical area of Autralasia and Asian fauna, place the island into the map of world biodiversity. Dozens of endemic birds, in addition to endemic mamals and floras, are inhabiting the island hinterland.
