We present movement data for a species of New Guinea “giant rat”, Mallomys rothschildi , as a test of the efficacy of a recently developed method of spool‐and‐line tracking in short‐term ecological/behavioural studies. We demonstrate that M. rothschildi is scansorial, feeds on shoots of Pandanus spp., and ranges freely over large areas without apparently being constrained by a fixed “home” nest. Another species, Hyomys golialh , occurs sympatrically and is superficially virtually indistinguishable from M. rolhschildi. Data from the single individual tracked suggest that the two species are ecologically segregated on the basis of clear behavioural differences. We note the considerable advantages of spool‐and‐line tracking over radio tracking in this type of study.
