Floss, Hammer, Throw

Next time you can’t bear to floss, consider this: a macaque might steal for such luxury. A charming new-ish book compiles and systematizes examples of tool use by our neighbors.

Tool use. It’s an irresistible topic – but one that’s often treated in a one-off fashion by researchers or writers hoping for splashy coverage.  Animal Tool Behavior offers quite the opposite: a lively overview of studies documenting all manner of tool-use by all manner of species. This 2011 tome is the joint work of three researchers: Benjamin Beck, Robert Shumaker, and Kristina Walkup. The matching quiz below offers a smattering of the diversity to in their book. (As for its elegant organization — which allows for quick comparisons across species — that you’ll have to see for yourself.) Enjoy!

a. Push Over – pilfer clothes from soldiers and then roll boulders at pursuers
b. Insert and Probe – use human hair for floss
c. Symbolize – treat leaf bundles as dolls
d. Hammer – use pebbles, twig bits, or seeds to pound shut burrows
e. Throw – shoot water at insects, observers’ eyes and lit cigarettes
f. Anoint – anoint oneself with rattlesnake scent
g. Absorb – dunk prey in water, perhaps to create a hydration aid

1. Chipmunk
2. Orangutan
3. Bird
4. Fish
5. Baboon
6. Wasp
7. Macaque

Solutions below….

  • f-1 – Siberian chipmunks have been observed draping themselves with snake skins, likely to mask the rodents’ own scent
  • e-4 – I suppose everyone knows about archerfish. But I didn’t know some shoot targets as far as 3 meters away.
  • a-5 – This incident was reported by a Lieutenant Shipp in 1810. The soldiers retreated, rather than be pelted from cliffs by a troop of baboons.
  • d-6 – For reasons I don’t fathom, 15 different research teams have documented Ammophila wasps tamping closed burrows in which they’ve laid eggs.
  • b-7 – Flossing is apparently a popular activity for macaques living near a Buddhist shrine in Thailand. (Several women there report hair-snatching incidents.)
  • c-2 –Young wild female orangutans have been observed at three different sights making leaf bundles and treating them like infants.
  • g-3 – In one study, Brewer’s blackbirds were seen dunking grasshoppers before serving them to offspring
