Drongo Cuckoo - Male

I found this Drongo Cuckoo in PPH Seloliman - Ngoro - Mojokerto - East Java. The first nature santuary plantations, my friend'd took me long time ago. Almost every weekend on saturday morning I came there for excercise, and clicking with my camera. I heard the calling of this bird is not too often, mingle with other cuckoos, and to find it, I must say I've got to be very lucky. This is the only picture I have of this bird. The color is absolutely gorgeus, shiny glossy black, and from the front has white barring undertail. The eyes is brown on the male and yellow on the female.
