Accuracy of estimated locations from models fit with and without a ψ parameter to re-scale Argos error ellipse sizes. The log difference in root mean squared distance (logΔ RMSD) from interpolated GPS locations was calculated for the two models fit to each individual animal. Negative values indicate the model with a ψ parameter is more accurate, whereas positive values indicated the model without a ψ parameter is more accurate. Results are pooled across species with individual log differences in RMSD displayed as species-specific shapes (gold, blue). The inner quartile ranges are beige boxes and medians are black bars
