Philippine Hawk-Cuckoo mobbed by a Black-naped Monarch

The Philippine Hawk-Cuckoo is a Philippine endemic ranging from the lowlands up to high elevations from the major islands of the Philippines. It was formerly lumped with the Hodgson's Hawk-Cuckoo but now regarded as as a separate species due to the difference in vocalizations. The breeding biology of Philippine Hawk-Cuckoo is poorly studied but it is most likely a nest parasite. It is a medium-sized bird, almost 12 inches from beak to tail but here it is being mobbed by a smaller Black-naped Monarch. The monarch most likely is defending a nearby nest while the cuckoo is just having his breakfast!
