Figure 5 in Quantitative assessment of species identification in aerial transect surveys for ice-associated seals

Figure 5. Frequencies of observed characteristics from images identified as pups (a) and nonpups (b) of four ice-associated seal species in the Bering Sea. Bars are stacked according to the frequencies of nine observed species and age class confidence categories. For pups, only those traits with at least one observation are included for each species. For nonpups, only traits with ≥ 5 observations are included. Trait definitions are provided in Table 1.
