I saw this Warbling White-eye (Zosterops japonicus) in higher elevation forest of District Sonder in Minahasa highland.
There were a lot of other birds in the nearby trees such as Crimson Sunbird, White-faced Cuckoo Dove, Sulawesi Cuckoo Dove, Sulawesi Blue Flycatcher, Black-faced Munia, Sulawesi Pygmy Hanging Parrot, and etc.
