Various methods for estimating animal density from visual data, including distance
sampling (DS) and spatially explicit capture-recapture (SECR), have recently been
adapted for estimating call density using passive acoustic monitoring (PAM) data,
e.g., recordings of animal calls. Here we summarize three methods available for passive
acoustic density estimation: plot sampling, DS, and SECR. The first two require
distances from the sensors to calling animals (which are obtained by triangulating
calls matched among sensors), but SECR only requires matching (not localizing)
calls among sensors. We compare via simulation what biases can arise when
assumptions underlying these methods are violated. We use insights gleaned from
the simulation to compare the performance of the methods when applied to a case
study: bowhead whale call data collected from arrays of directional acoustic sensors
at five sites in the Beaufort Sea during the fall migration 2007–2014. Call detections
were .....
