abr_data.csv: Data from experimental playbacks

Video_ID: Video segment with detection   

ABR#: Automated behavioral response system unit number   

Date: Date of observation

Pre_Not_alert: Amount of time not alert   before treatment broadcast   Total_Pre: Total amount of time before   treatment broadcast   

Prop_Alert_Pre: Proportion of total time   alert (vigilant) before treatment broadcast   

Post_Alert: Amount of time alert   (vigilant) during / after treatment broadcast   Post_Not_alert: Amount of time not alert   during / after treatment broadcast   

Total_Post: Total amount of time during /   after treatment broadcast   

Prop_Alert_Post: Proportion of total time   alert (vigilant) during / after treatment broadcast    

Fletcher_etal_code.R: R code used for analyzing data

Generalized linear mixed models used for testing effects of treatments on the probability of running and the proportion of time spent vigilant.
