This species was previously considered conspecific with C. vauxi, C. viridipenis and C. pelagic and is normally difficult to differentiate from other Chaetura. Its name Chaetura derives from the Greek roots khaite = hair and oura = tail. The epithet chapmani was established in honor of the American ornithologist and collector Frank Michler Chapman.

The limpkin (Aramus guarauna), also called carrao, courlan, and crying bird, is a bird that looks like a large rail but is skeletally closer to cranes. It is the only extant species in the genus Aramus and the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks.
