Migration Info This species winters from the extreme southern United States (Texas and Florida) to the Peruvian Andes. It displays extreme variability in the types of habitats in which it is found both during winter and on migration. The only requirement seems to be the presence of trees on which this bark specialist can feed. It is among the earliest species to reach the U.S. Gulf coast in spring, often appearing in early March in significant numbers. This is one of the most common "vagrant" warbler species in spring along the west coast, perhaps indicating that migratory routes of the westernmost populations are scattered throughout the western states.
