Movement patterns of honey possums, Tarsipes rostratus, in the Fitzgerald River National Park, Western Australia

The movements of marked honey possums,Tarsipes rostratus, were studied using mark–recapture with pitfall traps in heathland on the south coast of Western Australia. Most individuals moved less than 30 m even over several months, with no evidence of marked dispersal. We suggest that this lack of mobility is associated with a detailed knowledge of the locations of those plants that supply all the species’ food. Males moved slightly further than females, possibly to search for mating opportunities and possibly because females exclude males from rich nectar sources. In consequence, the home ranges of males (1277 m2) were significantly larger, on average, than those of females (701 m2)
