Migration Info Worm-eating Warblers are found almost exclusively in undisturbed forests in their winter range. They depend on a well-developed layer of leaf litter, where they employ their unique style of feeding by probing and opening rolled leaves. The highest winter population densities are reached along the Caribbean slope of Central America and in the Greater Antilles. Unfortunately, forest destruction in these regions is a serious threat to this species. Worm-eating Warblers arrive along the U.S. Gulf coast as early as mid-March; the peak passage of this species through the Gulf coast region and Florida is in early April.
