Kakadu Pebble-mound Mouse

Pseudomys calabyi

The Kakadu Pebble-mound Mouse is a remarkable native rodent, not a pest, known for its unique architectural behaviour. This species, found only in the rocky escarpments of the Top End, constructs mounds of small pebbles over its burrow entrances. These mounds can be extensive, containing thousands of stones, and are thought to protect the burrow from flooding during the wet season and maintain a stable temperature and humidity inside. The mouse is a habitat specialist, relying on the specific conditions of the sandstone country. It is listed as a vulnerable species, threatened by habitat changes caused by inappropriate fire regimes that reduce its food supply and cover.
