Classifications of smolt tags as predators (black bars) or smolts (gray bars) by the end of the study of acoustic-tagged Chinook salmon smolts according to four filtering approaches: simple rule-based filter (a), complex rule-based filter (b), smolt-only pattern-recognition filter (c), and multispecies pattern-recognition filter (d). White bars in a, b, and c are placeholders for the known predator tags used in the multispecies pattern-recognition filter (d). Tags are ordered according to a Ward hierarchical cluster analysis of behavioral metrics from the multispecies pattern-recognition filter (dendrogram shown). The red dashed line indicates distance threshold used to divide the multispecies dataset into five clusters (numbered 1–5); clusters 1, 4, and 5 were classified as predated
