Temperature-sensitive datalogger deployment and retrieval (bat recapture) data, by study year, hibernacula site number (see Fig. 1), and sex for the 504 loggers deployed.

Whether data were successfully downloaded from the logger and ultimately used in the analyses of this paper, are also described.*# of males/# of females and date of deployment or retrieval of loggers.**bats were occasionally excluded from analyses due to incomplete data (e.g., BMI not recorded) or problems with downloaded data.+loggers only deployed mid-winter (January-March) as opposed to the full-hibernation season (November-March).
