Gibbons

Some illustrations I ran into while searching for chimp articles.  I think it is true that some primates will throw feces at someone they are unhappy with.  I didn't know they have such a range of other ways to let someone know they don't like them.  I'd say our behavorial repetoire is lacking in comparison.

  

Fig 1 Hostile presenting toward humans or gibbons or both. It may incorporate 1 or 2 hands for balance....During the hostile present, the gibbon bent over from the waist and elevated its anogenital area while hanging vertically from the enclosure, or while standing (Fig.  1 ).

A female Hylobates pileatus hanging on the side of the enclosure.....Generally the knees were flexed, with the posterior directed toward the target (Figs.1 and 2 )....When a ....female Hylobates pileatus....hostile presented toward humans or to gibbons it included >1 of the following: lips pushed out with a strained face (Fig. 2 ), vibrating the substrate, shaking a branch or wire mesh while the buttocks are shaking, slight raising and lowering the buttocks, a rigid body, intense staring, and a squeal. The gibbon frequently looked around or under its forelimb observing the recipient during the present, or with its hind limbs nearly straight looking between its legs (Figs.1 & 3 )

I think we should all adopt position 3 next time someone pisses us off. I am willing to record reactions and send them on to you for further research.

Position 3 really makes the message clear, doesn't it? I'd be worried about falling over, which would somehow undermine the whole display.
