Humans are not the only mammals capable of deceiving their own kind. That is the conclusion of a study focusing on Cantabrian brown bears, carried out with input from experts at the CSIC, the FAPAS, several Spanish and European universities and the Principality of Asturias.
The study published in the 'Journal of Mammalogy' (source in Spanish) argues that a minority of the bears living among the peaks of León, Asturias and Cantabria may be 'lying' about their true size to avoid having to face larger rivals. How? By using the signs and markings these mammals leave in their surroundings to stake out territory.
