  1. Activity sensors with a * suffix indicate acoustic tags. “No fit” indicates that the long-term component of the time-series did not follow an exponential decline and that an exponential model could not be fitted; “No rec” indicates that it was possible to fit an exponential model to the time-series but that recovery thresholds and times were not assigned because the fitted exponential model did plateau
