Island Girl Slows A Bit

As Island Girl proceeds up the Chilean coast towards the Peruvian border, she is slowing some. Her daily jumps have decreased in length. Yesterday, she flewonly 96 km (60 miles), her second shortest hop of the migration so far.

It is not really clear why peregrines cover a great distance one day and a short distance the next but they do. Perhaps they are tired, maybe the weather conditions are poor, possibly it is too hot, or there might even be a food source that they want to exploit, who knows?

She is now about 139 km (86 miles) south of the Peruvian border.

The area she is roosting in, a prominent river valley near the town of Pisagua, has been used in the past by our other tagged birds. She slept on a hillside directly above a secondary road.
