Small Marsupials


PHOTOGRAPHY OF SMAL MAMMALS FOR IDENTIFICATION

Most photos of small terrestrial mammals submitted to Canberra Nature Map for identification that were photographed in the Canberra suburban area are of a Black Rat (Rattus rattus).  The next most likely species is the House Mouse (Mus musculus). Outside the city, at present, photos of Black Rats outnumber all other small mammal photos combined. However you may have found something different.  Here are some tips for what to include in your photos to increase the potential for correct identification:

  • An image that is sharp, not blurry;
  • A scale;
  • A view of the whole animal (preferably stretched out if it is a carcass);
  • Views of every surface -  (not always possible but ideally this includes a profile of the head, good views of the ears, the belly, the pads on the hind feet, and a good view of the fur and  skin on the tail from below and above);
  • Views of the teeth; and
  • A count of the number of teats.

Based on the teeth it's an Antechinus. It could be A. flavipes or A. stuartii, but hard to say given its state.

I agree with this one being Antechinus flavipes. The BCT bait stations are great for size reference.

Now, here is your Antechinus! I suggest its a yellow footed with that grey head and brown / rufous body but perhaps Martin can confirm.

Darn indeed. FYI, its the overall size of the animal (an antechinus would be half the size), the shape of the head and mouth (rodents have two large incisors and the mouth tends to be smaller and more at the front of the head), the size of the tail, and in this individual (male) its the shape of the testicles (in Antechinus the testicles are more round and further forward).
