Argus monitors like to stand on their hind legs to bluff antagonists, fight rivals, catch a limb to climb on or a bit of meat above their head, or just to look around.
Oz stands up near her nest box for a look about.
Here, Oz demonstrates not only her impressive bipedal posture
but the long tongue of the monitor family as well.
I had to tempt Chris with a bit of food (out of view in this photo)
to get her to stand up for this shot. Unlike Oz, my other arguses tend to
be reluctant to stand up when the camera is ready.
