Analysis of detection effort and cost per detection for acoustic monitoring and camera trapping

	Acoustic captures	Acoustic capture rate	Cost Per acoustic capture per 1,000 trap days	Camera trap captures (estimated)	Camera trap capture rate	Cost per camera capture per 1,000 trap days
Bartlett's Tinamou	85	1,676.9	$1.67	0.029	3.1	$406.71
Cinereous Tinamou	131	2,584.5	$1.08	0.063	6.6	$191.03

Camera trap captures are estimates made by applying the capture rates reported in Mere Roncal et al. (2019) to the survey duration of the acoustic monitoring project. In this system, the acoustic monitoring survey method collected detections at a 301× higher rate than camera trapping while being 147× less expensive per unit effort.
