Has been placed in separate genus, either Cerchneis or Tinnunculus. Often considered a member of the F. tinnunculus group (see latter species). Race sparverioides appears distinctive, occurring as two morphs (pale and dark), but otherwise not different from other races. Seventeen subspecies normally recognized.
