Grooming in the Greenhouse

June 15, 2026 by J.B. 3 Comments

Of the many reasons why chimpanzees engage in social grooming (also known as “allogrooming”), hygiene is thought to be one of the least important. Grooming appears to be much more about strengthening bonds, lowering stress levels, and gaining favors. But evidence suggests that hygiene still plays an important role, as chimps often concentrate on parts of the body that are less accessible to their grooming partners. Because of this, there generally aren’t any parts of the body that are off limits, including noses and backsides.

    Lol, thx for the heads up, JB!
    What’s a little grooming, between besties?
    When I visited s friend in Perú, I rolled in after a few days in Cuzco without heat or hot water in the hotel. I’d already had a cold (me being me, that meant laryngitis), food poisoning, and a minor setback.
    My friend’s husband, hearing me coughing, came at me with cough syrup and made me take some. She then shared, in English, a story that let me know I was getting off lucky!:smile:

    Do the other members of Negra’s group take extra care with her, realizing she can’t move well any longer? Or do they simply treat her like one of the gang? Being a senior myself, I empathize with her struggles.

    Seeing Annie grooming Missy was a true treat! Annie’s “raspberries” were very funny especially when issued as if she was saying “All done—time to shift position”. Plus, Annie added a gentle little pat-pat on Missy’s arm or wherever. So sweet.

    Burrito and Negra, he is so gentle with her. And I can’t get over how bright and beautiful Neggie’s face looks. Look at her! Amazing!
