The mourning warbler (Geothlypis philadelphia) is a small songbird of the New World warbler family. Mourning warblers are neotropical migrants native to eastern and central North America and wintering in Central and South America. They tend to be found in dense second growth forests. They are very similar to the MacGillivray's warbler in appearance, especially in females and immature birds, but their breeding range does not overlap into the west. The "mourning" in this bird's name refers to the male's hood, thought to resemble a mourning veil. Wikipedia →
