White-headed Munia in Javanese it is called Emprit Kaji, often called Bondol Haji (Indonesian). I photographed this bird last weekend. Actually there are five or six of them, but I could not shoot the others.
There are aslo many other smaller birds (Munias), but they are not so easy to get closer to. Some other day I am very sure will photograph them. I need a longer lens, I think.
