The American Redstart is commonly found in secondary forests zipping through the trees chasing after flies.  It looks like a miniature Baltimore Oriole. Cornel Lab describes the song:   "During breeding season the male sings a series of 2–11 thin, high-pitched notes, sometimes ending with an accented phrase. The building energy of the song and the abrupt, accented ending lead some people to describe the song as sneeze-like."
