(A) Panel illustrating the full set of observed locations (grey pluses), the MCD-regularized locations (, blue circles), the calculated GC route (grey line) and the deviations () between the GC route and the MCD-regularized locations (red lines). The blue triangles indicate the determined start and end points of the GC route. (B) Enlargement of the region contained by the box in panel (A). The estimated true locations (, red circles) were derived from the estimates of . (C) Robust nonlinear smoother (blue) fit to MCD-derived travel rates (grey). The vertical red line denotes the peak travel rate associated with the onset of migration. Note that the smoother was not fit to the first week of data because these elevated speeds are likely a post-tagging behaviour. (D) Robust nonlinear smoother (blue) fit to MCD-derived longitudes (grey). The vertical red line denotes a large change in direction of travel potentially associated with the cessation of migration.
