This allowed us to look at if there was an effect of any one individual caller on the number of birds recruited - for supplementary analysis). Description of datasheet 2019Intercoder.reliability.csv video = video number (videos for independent coder were randomly chosen) sd.recruits = number of recruits recorder from video by independent coder jc.recruits = number of recruits recorded from video by Jenny R. Coomes Description of datasheet 2019. Withoutrepeatcalling.csv This datasheet is the full dataset with the playbacks that contain repeat calls from the same individuals removed.
