Ordination plot of smolt tags (points) along the first and second principal component axes based on summarized tag-level metrics for smolt-only pattern-recognition filter. Tag classification as smolt or predator was based on partition of data into two clusters in Ward hierarchical cluster analysis. Labeled vectors are relative PCA loadings of observed behavioral metrics from full smolt-tag data set
