# Hibernating female big brown bats (Eptesicus fuscus) adjust huddling and drinking behaviour, but not arousal frequency, in response to low humidity ## Description of the data and file structure The excel file has four different sheets that contains (listed in order): **Sheet1_Video Data - arousals**: arousal begin and end time/date, bat ID, humidity treatment, drinking bouts, and associated starting body mass (prior to hibernation) and ending body mass (end of hibernation)) **Sheet2_Video Data - torpor:** torpor begin and end time/date, bat ID, humidity treatment, and associated starting body mass (prior to hibernation) and ending body mass (end of hibernation)) **Sheet3_Arousal Definition Data**: bat ID, humidity treatment, arousal begining and end data/time, and associated skin temperature threshold. Note: arousals for video data do not have an associated skin temperature threshold. **Sheet4_Huddle Size Index**: photo date and time, humidity treatment, file name, and huddle measurements by observer 1 and 2.
