ムジヒメウソ Sporophila simplex

Well-named seedeater found in arid scrub and adjacent farmland in western Peru and southwestern Ecuador. Its best field marks are the distinct wingbars and bill color (pinkish on breeding males, nearly black on other individuals). Bill is smaller and less bulbous than that of Parrot-billed Seedeater. Sometimes found alone, but loose flocks may converge on areas with abundant food, such as fields of seeding grass. Males often sing a short series of buzzy notes.
