Table 3. Model summary tables for probability of prey capture success, Foraging Efficiency Index (FEI) and Dive Efficiency (DE) as predicted by Support Vector Machine (SVM) and as observed on camera.

The abbreviations SC (St Croix), P (pelagic), F (female) and the symbol “:”, indicating an interaction between explanatory variables, are provided where possible. “Seabirds” and “multi” indicate where seabirds or seabird, fish and sharks were present during feeding events, respectively.
