The American redstart (Setophaga ruticilla) is a stunningly colorful warbler, often found flitting through the trees in wooded areas of North America. This bird is commonly known as the "redstart," but it also goes by other names, including the "red-tailed flycatcher," "firebrand," "rufous-crowned warbler," "yellow-tailed warbler," and "red-tailed warbler." These names all refer to the bird's distinctively bright orange-red patches on its wings, tail, and sides. Not only is the American redstart a beautiful sight to see, but it also serves an important ecological function as a seed disperser and insect predator.
