Birds of the Wola region are numerous, varied and colourful, ranging from the large ﬂightless cassowary to various small ﬂycatchers, from colourful parrots and lories to soft-hued pigeons, and from numerous honeyeaters to some of New Guinea’s renowned birds of paradise, among many others. Although not always seen in the sometimes dense vegetation, they can often be heard singing near and far. Common furry animals include cuscuses and possums, together with tree kangaroos. A wide variety of rodents, including giant rats also occur, as does the egg-laying quilled echidna, a rare animal of remote forested regions. The reptile and insect populations are also numerous and varied, and there are also, according to local people, frightening forestdwelling demon spirits. Their zoological taxonomy assigns the majority of named animals to one of six ‘family’ (sem) or life-form categories: ‘birds’ (sor), ‘large furry animals’ (sab), ‘small furry animals’ (honez), ‘frogs’ (jiya), ‘ﬁsh’ (wen) and ‘insects and some reptiles’ (elelbiy). A few other animals stand on their own as unique ‘unafﬁliated taxa’, such as ‘pythons’ (burun), ‘dogs’ (shaen), ‘pigs’ (showmay) and ‘human beings’ (tenol). Such ethnozoological arrangements are common throughout the Highlands: the Gimi of the Eastern Highlands (Glick 1964: 275) and Kalam of the Schrader mountains (Bulmer 1974a), to cite two examples, have similar categories.
