Carlton first moved east to a large foraging aggregation and roost site on the western edge of Lake Okeechobee in Glades County, Florida, on 7 July. After 28 days, he flew 25 miles south to another core roosting area for an additional six days, feeding on insects and adding further to his fat reserves. His migratory restlessness got the best of him on 10 August, when he flew to the westernmost Everglades for one last night in the United States. The next day, he crossed the Straits of Florida for Cuba and continued west over land before striking out over the ocean once again from the narrow tip of the Guanahacabibes Peninsula. After 400 miles over the Gulf of Mexico, Carlton arrived on the Yucatan Peninsula on 13 August. A week later, Carlton is still resting and feeding on the Yucatan, the only major stopover point for the U. S. breeding population on its 5,000 mile southbound migration.
