Neotropical migratory birds are those species that nest in North America and migrate to the tropics to spend the winter. In South Carolina 47 percent, or 53 species, of our nesting land birds are considered neotropical migrants. They include such familiar birds as purple martins, ruby-throated hummingbirds and whip-poor-wills but also less-well-known groups such as warblers, vireos, tanagers, orioles, flycatchers and thrushes. Neotropical migrants are among our most beautiful and musical birds.
