The birds of VB include a number of interesting carnivores:

• The Javan hawk-eagle and two other kinds of eagle, which can often be seen soaring over open ground at VB by day seeking prey and sometimes soaring between pine trees in the pine forest opposite VB.
• The Sunda owl, which hunts by night.
• A fishing owl, which hunts by night in the fish ponds at VB, using its fecal pelets to lure fish to the service.
• Various cuckoos (wiwik) of the genus Cacomantis. Thus insectivorous genus isnoted for the habit of laying its own eggs in the nests of other birds – brood parasitism. The young cuckoo, who is raised by a surrogate mother, waits for an opportunity to kill his foster-siblings.  Wik­i­­­pedia: “The genus name is derived from the Greek kakos meaning evil or ill-boding and mantis for prophet and is derived from their association with "rains" being supposed to be predict ill fortune and bad weather.” Thewiwik has the same reputation in Java.
