Sorry for the late report. It has been busy here for the last few days.
On Wednesday, Island Girl continued to fly NW, apparently crossing over a tip of the border with Ecuador before re-entering Peru. Still taking it easy, she covered only 139 km (86 miles) for the day.
Her roosting site (elevation 675') was pretty unique. She slept in a brushy area among the dry hills of a tributary of the Rio Tumbes. She was about 14 km (8.7 miles) inland from the coast and the Pan-American Highway and only 40 km (25 miles) from the border crossing into Ecuador.
She was also near the northern Peru city of Tumbes. If you look at this region on Google Earth, you'll see the beginning of the coastal mangrove habitats ("manglares") that typify the change from desert to tropical rain forest.
