Lateralization of splay posture in reticulated giraffe (Giraffa camelopardalis reticulate).

Motor laterality is quite often studied in non-human primates, but rarely has been investigated within ungulates. The aim of the study was to use the naturally occurring splay behavior in giraffe as a method to look for the presence of laterality. Four male giraffes housed at Zoo Atlanta were watched for three months, recording their first leg moved to begin the splay posture and the total number of leg movements to achieve a secure stance. All four giraffe significantly moved their left leg first to begin the stance, which suggests at least individual level laterality. However, using the number of leg movements overall, the last leg moved was only significant in one individual.
