Observations and telemetry‐surveys of feral Camargue coypus showed dusk‐ and night‐activity. Start and end of activity were correlated with sunset and sunrise respectively but influenced by climate and animals' individual history. A comparison with captive coypus in Britain showed differences caused by the stable social and abiotic environment, food‐quality and proximity of feeding‐ and resting‐places in the cage. Resting in close body‐contact — frequent in a stable environment — occurred very seldom in Camargue coypus. In this species, two behaviours of the two‐oscillator‐model for activity‐control could occur in different activities.
