Schematic representation of the N-mixture model of correlated abundances for 3 species.

<p>Solid rectangles correspond to observed quantities (covariates or individual capture histories). Dashed circles correspond to latent random variables. Notation is described in Multispecies N-mixture model of correlated abundances. Covariates of abundance (LPC1, LPC2, VPC1) and detection probability (DAY OF YEAR, TIME OF DAY) are described in Statistical analysis of avian data.
