The rodent had lost power in it's back feet when discovered. It was given shade and water but sadly transpired within the hour. It was given a brief funeral and buried outside the grounds of the Boundless Canberra All-abilities playground.
Rattus rattus can be a variety of colours so fur colour is not a good guide. Ears look like they would have reached the eye if bent forward, indicating Rattus rattus but tail looks a bit short for R rattus whose tail would reach past its nose. Feel like exhuming it to check Rob? Then you could have a second, longer, funeral ceremony.
