Burrowing Behaviour of the Northern Hopping-Mouse (notomys Aquilo): Field Observations

We describe burrowing behaviour of the elusive northern hopping-mouse (Notomys aquilo) recorded by camera traps. New burrows were observed at the beginning and end of the wet season on Groote Eylandt, Northern Territory. Initial burrow entrances were open for approximately five days before being back-filled, leaving only a spoil heap with pop holes (burrow entrances) up to 5.3 m away. These results will improve survey techniques for this cryptic, threatened species.
