On Sunday, Island Girl continued to fly north through Ecuador and crossed the equator.
She flew 166 km (103 miles) for the day, passing by the coastal city of Esmeraldas.
Despite still being in Ecuador, she has now officially migrated back into the northern hemisphere.
She also returned to the Pacific coast and roosted in some trees only 938 meters (1,000 yards) from a broad, sandy beach.
Lots of habitat photos are available on Google Earth.
She was not far, just 3.7 km (2.3 miles), from the main highway (E-15) connecting Esmeraldas to the interior.
