Prairie Warbler
Setophaga discolor
These birds have yellow underparts with dark streaks on the flanks. In males, the back is olive green with chestnut or rufuos streaks. A black stripe runs through the eye, and another black stripe runs from the beak down the throat. This semicircular stripe gives them a distinctive "tired" look. They have two faint wing bars. Their tails have large white areas, and they have dark legs. Coloring is duller in females and immature birds, and streaks are fainter or absent. The subspecies S. d. paludicola is also duller overall. Voice: Prairie warblers have two categories of songs, referred to as Type A and Type B. Type A songs are typically a series of ascending buzzy notes. The B songs are an ascending series of whistled notes that often contain some buzzy notes. Compared to A songs, the B songs are lower in pitch and have fewer, longer notes. The total song length is longer as well in Type B songs.
