This Corvus specimen was recorded on a small island near the western shore of Flores, East Nusa Tenggara, Indonesia. With respect to the locality, I suggest that it may be C. florensis, an endemic species of the West Flores region.
Ivan, perhaps https://www.researchgate.net/profile/Kathryn_Monk may be able to help you with that, she is the author of the Ecology of Nusa Tengarra and the Maluku

It's C.macrorhynchos to me. It's the commonest bird in Sri Lanka.
What is the size of this specimen???
Comparatively ,Corvus macrorhynchos is much larger than the Corvus florensis.
Are all pictures from the same bird? Especially on image 3+4 the bird seems to have a very large bill with a high culmen. This suggests macrorhynchos. The Flores crow is barely larger than a jackdaw.
Best wishes,
André
Dear colleagues, thanks for your suggestions. It was a single specimen. Sorry, I don't remember its size although based on photos it seems to be rather large (surely larger than a jackdaw). Best wishes, Ivan
So it should be a Large-billed Crow. But I have never seen florensis, I only know enca quite well. If you want to confirm the determination you can contact the Oriental Bird Club http://orientalbirdclub.org/contact/
