On Saturday, Island Girl continued NW, crossing the border into Mexico. She flew 241 km (150 miles) for the day.
She is still following the coastal foothills of the Pacific and is now approaching the Isthmus of Tehuantepec, a break or low point in the central Sierra. This is a well known point of cross-over for fall migrant hawks of many species, including Broad-winged Hawks, Swainson's Hawks and Turkey Vultures. Obviously, it is also used during the northbound migration. The dominant local peak is Cerro Atravesado, over 2,200 meters in elevation. The "pass" is just north of this mountain.
Her current heading will take her towards Veracruz, 445 km (277 miles) to the NW.
She roosted in the forests of the coastal foothills on Cerro Bernal Visto at 924' elevation. She was just above the Pan-American Highway situated 1.3 km (.8 mile) below her, and once again, it appears that she could see vehicles driving along the road from her vantage point.
There are several blue box photos of this site on Google Earth. Pretty interesting peak.
She was about 15 km (9.5 miles) inland and not far from a salt-water bay to the west called La Joya.
Island Girl is migrating past the south end of a very long sandy beach (Playa Aguachil) with an extensive back bay called the Mar Muerto or Dead Sea. It looks like superb habitat for shorebirds and gulls. No doubt there are several peregrines wintering there.
