Animals exhibit consistent individual differences in their movement: a case study on location trajectories of Japanese macaques

Researching individual recognition (IR) is essential to understand the life history and adaptive behavior of social animals. Investigation of possible IR clues may also help us build new hypotheses about how social animals distinguish between different individuals. This study investigates behavioral...

Investigation of possible IR clues may also help us build new hypotheses about how social animals distinguish between different individuals.

Using a recently developed tracking system based on Bluetooth® Low Energy beacons, we collected three-dimensional (3D) location data from five Japanese macaques living in a group cage. A non-parametric, neural network-based analysis of the data revealed the existence of consistent individual differences in extremely limited aspects of the movement data (2-min trajectory of 3D location).
