Mouse on grass stalk at Deramakot – any clues?
I recently finished a couple week trip to Sabah focused mainly on mammals – particularly orangutan, gibbon, other primates, wild cats and civet (but I am interested in all wild life).
On a night drive at deramakot, we came across a little mouse that was sleeping on the end of a tall grass stalk. The stalk would probably be 1.5 meters tall if straight, but mouse was at the very end, so the stalk was bent over, but still probably a meter off the ground. I thought that was odd, and snapped a not very good picture.
A couple minutes later we saw another one, and I got a better picture. One mouse doing this is odd, but two is a pattern. So I thought well, this must be some well known behavior that I’ll look up when I get home. Except I can’t find any mention of it. The mouse that is frequently seen on stalks is a harvest mouse on wheat or other grain, but obviously that is not what is going on in Sabah.
Unfortunately the mouse is curled up in a ball and facing away from the camera so it may not be very diagnostic. It looks to me like a Ranee Mouse (aka Lesser Ranee Mouse, Haeromys margarettae), but I defer to those with greater expertise.
Does anybody know about this? Either the identity of the mouse, or the behavior of sleeping on grass stalks.
Here is the picture.
