Liolaemus lorenzmuelleri is a lizard endemic to Chile. Some authors indicated that its activity pattern was unimodal; however, no evidence was found to support this statement. The objective of this study was to verify the unimodal activity pattern of L. lorenzmuelleri, based on quantitative data. Thirty-five videos recorded between August and December 2022 of an individual of the species were examined. The times and dates of recording were analyzed with the Kernel density function. It was concluded that the species exhibited a unimodal activity pattern for the study period.
