Bali Island is though to be the last island of Wallace line that separates the flora and fauna of Mainland Asia and Australia, but in Bali Island there are no kakatoe birds, but one finds plenty of them in the islands East of Bali, e.g. in Sumba and Flores.

A very few are found in Nusa Penida. There are more snakes and beautiful myna colored birds. The Australian flora and fauna are supposed to begin in Lombok, the island just East of Bali.

In Nusa Penida one occasionally sees the white kakatoe and the Horned bill; a bird with very large beak, too big in proportion with the head, and the body.
