1. When they visit and revisit specific areas, animals may reveal what they need from their home range and how they acquire information. The temporal dimension of such movement recursions, i.e., periodicity, is however rarely studied, yet potentially bears a species, population, or individual-specific signature. 2. A recent method allows estimating the contribution of periodic patterns to the variance in a movement path. We applied it to 709 individuals from 5 ungulate species, looking for species signatures in the form of seasonal variation in the intensity of circadian patterns. 3. Circadian patterns were commonplace in the movement tracks, but the amount of variance they explained was highly variable among individuals. It increased in intensity during spring and summer, when key resources were spatially segregated, and decreased during winter, when food availability was more uniformly low. Other periodicity-inducing mechanisms supported by our comparison of species- and sex-specific patterns involve young anti-predator behavior, territoriality, and behavioral thermoregulation. 4. Model-based continuous-time movement metrics represent a new avenue for researchers interested in finding individual-, population-, or species-specific signatures in heterogeneous movement databases featuring various study designs and sampling resolutions. However, we observed large amounts of individual variation, so comparative analyses should ideally use both GPS and animal-borne loggers to augment the discriminatory power; and be based on large samples. We briefly outline potential uses of the intensity of circadian patterns as a metric for the study of animal personality and community ecology.
