Behavioral differences as predictors of breeding status in captive cheetahs
Authors:Nadja C Wielebnowski
Abstract:Individual behavioral variation of 44 adult captive‐born cheetahs, Acinonyx jubatus, was assessed using observer and keeper ratings on a variety of behavioral attributes. Inter‐rater consensus was high for most questionnaire items, several of which were significantly correlated with direct behavioral measures recorded in a mirror‐image experiment. Principal component analysis was applied to identify patterns of individual variation as measured by observer and keeper ratings. Three major components, labeled as tense‐fearful, excitable‐vocal, and aggressive, accounted for 69% of the observed variation. Females showed significantly higher scores on the component tense‐fearful than males. Non‐breeders of both sexes scored significantly higher on the component tense‐fearful than breeders. Assessment of individual behavioral variation through questionnaire ratings may therefore provide a simple and non‐invasive tool for predicting an individual's ability to adjust to the constraints of certain husbandry regimens and to reproduce in captivity. Simple measures of behavioral attributes may offer new insights for solving breeding problems and improving conservation management of endangered species in captivity.
