title: A note on motor laterality in plains zebras (Equus burchellii) and impalas (Aepyceros melampus).
abstract: This observational field study used intermittent still photography to examine the distribution of motor laterality in images of two African grazing quadruped species: plains zebras (Equus burchellii) and impalas (Aepyceros melampus). Zebra images (n=708) had a laterality index of -6.21 and a Z-score of -1.65 (p=.098). Impala images (n=318) had a laterality index of -18.87 and a Z-score of -3.36 (p=.0008). The weak left motor bias in zebras aligns with that reported in domestic horses using a related method.
