It took Island Girl about 10 days to reach Peru. Yesterday, she covered 229 km (142 miles) and left Chile behind. She has flown a total of 1,995 km (1,239 miles) so far on her migration north.
It appears that she flew past Arica (Chile) and then Tacna (Peru), before continuing almost due north into the desert foothills instead of following the curve of the Pacific coastline towards the west.
This is a departure from the norm. She is also moving up into the Andean highlands as she continues her migration. Whether she turns west or not remains to be seen but this is a natural place to leave the shoreline. She may be following a migratory bearing north and not a leading line (northwest) in this case.
