Black-and-white Warblers, Mniotilta varia, spend their winters in Florida and California, with some migrating all the way to northern South America. These medium-sized warblers can be found in a number of habitats including forests, wetlands, mangroves, and urban settings.
Insects and butterfly larvae make up their diets. Look for these agile birds on tree trunks and thick limbs where they use their downcurved bills to probe moss and bark to pluck insects.
