The crescent-chested warbler (Oreothlypis superciliosa) is a small, New World warbler that is found throughout North and Central America from Texas to Nicaragua. This bird is similar to other warblers, however, certain features set them apart. This warbler is noticeable different than most warblers due to its brightly colored plumage and distinct features such as a white supercilium and orange crescent on its breast. Crescent-chested warblers create their nests near the ground and eggs are incubated by the female. Furthermore, there are differences in the plumage of these warblers depending on their age and sex such as down in young birds and more present crescents on male birds. These birds are foragers and eat insects. They are also migratory birds and normally survive in flocks. Lastly, the crescent-chested warbler has a number of predators including rodents and other avian predators.
