Wild boar have a good nose for truffles. But not for acorns, says PhD student Lennart Suselbeek of Wageningen University. Looking for acorns they search randomly, according to research into how wild boar search for hidden acorns.
Suselbeek comes to that conclusion based on experiments in the lab and in nature. The aim of the study was to determine whether wild boar have influence on the way that wood mice hide acorns. Wild boars, like mice, love acorns. So they are competitors. But when it comes to defending its stock, the mouse is no match for the boar. It must be smart. They cannot be smart by hiding everything at the same place, but by making many different small stock sheds. So, risk spreading.
