30th of july. Aroud 5PM. 1 adult and 1 immature circling along and above the limestone cliffs. Impressive raptor... At the same time, a family group of Delacour's Langurs lazed around. Hmm hmm... I don`t know if any cases of Bonelli`s predation on this rare primate have been noted there. The adult weight of a langur is about 7-10kg, so not small deal even for such a predator. But the young ones...
The 2nd of last may, I observed a Bonelli's immature flying low and quickly over the marsh, scolding by some Chinese Pond Herons. It perched on a rock, just above a small pagoda, not far from the dyke (200m), on the left side, and began to tear apart its prey (a bird, identication impossible).
Van Long, a paradise for birders, a well-stocked pantry for others...
