The Bat Falcon (Falco rufigularis) is a falcon that is a resient breeder in tropical Mexico, Central and South America and Trinidad. It was long known as Falco albigularis; the name Falco fusco-coerulescens or Falco fuscocaerulescens, long used for the Aplomado Falcon, are now believed to refer to the present species (AOU 1948).
