The bat falcon (Falco rufigularis) is a falcon that is a resident 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. It is probably closely related to and looks like a small version of the orange-breasted falcon. These two, in turn, are probably closest to the aplomado falcon and constitute a rather old American lineage of Falcos.
