Magnolia Warbler
This warbler was first discovered in magnolia trees in the 19th century by ornithologist Alexander Wilson, but the birds were actually migrating to the northern coniferous forests where they breed. They winter from Mexico to Panama. and the species is occasionally found in the West Indies and even the western and southern United States—as well as from sea level to 1,500 meters in elevation! The color patterns vary, depending on the Magnolia Warbler's stage of life (breeding or not-breeding; adult, juvenile, or first-yea; male or female, etc.). Breeding males have a black face.
