Under a few pinecones when placed. Watch for downhill mountainbikes! Theres a fairly well defined track, but it is up a hill and not marked so make sure you are in tramping/ navigation mode!
Interestingly, the Ruru is not as NZ specific as you might think.The southern boobook (Ninox boobook) is a species of owl native to mainland Australia, southern New Guinea, Timor and the Sunda Islands. It was considered to be the same species (conspecific) as the morepork of New Zealand until 2013. Birds from Tasmania belong to a taxon, leucopsis which appear to be more closely related to (and hence treated as a subspecies of) the New Zealand species. Eleven subspecies are recognized. This bird is the smallest owl on the Australian mainland and is the continent's most widely distributed and common owl. It is predominantly brown in plumage with grey- or yellow-green eyes. It feeds on insects and small vertebrates.
