A Case of Brood Parasitism of Olive-backed Pipits Anthus hodgsoni by the Horsfield's Hawk Cuckoo Cuculus fugax

Abstract

We report a case of brood parasitism to the Olive-backed Pipit Anthus hodgsoni by the Horsfield's Hawk Cuckoo Cuculus fugax on Mount Fuji in Japan. The hawk cuckoo lays its eggs, mainly in the nests of the Blue-and-white Flycatcher Cyanoptila cyanomelana, Siberian Blue Robin Luscinia cyane and Red-flanked Bushrobin Tarsiger cyanurus. There has been only one clear report that the Olive-backed Pipit was parasitized by the hawk-cuckoo. Our report is a presumable second case.
