Trick question: what color is the yellowthroat's throat?
The common yellowthroat (Geothlypis trichas) is a beautiful warbler that measures between 4 and 5 1/2 inches in length. There are four varieties of adult males. The Eastern family is dark brown with a grayish frontal band and sometimes a broken, whitish eye ring. The birds from the Western interior are paler and grayer, with limited yellow on the throat and a whitish frontal band. The Southwest version is a slightly larger bird. They are a bright olive color and have an all-yellow underside. The black mask may be a reduced size behind the ear coverts, which are tinged with yellow. The Pacific yellowthroats are small, dark brown birds with white frontal bands and yellow below.
