Wikipedia Abstract

The spectacled owl, Pulsatrix perspicillata, is a large tropical owl native to the neotropics. It is a resident breeder in forests from southern Mexico and Trinidad, through Central America, south to southern Brazil, Paraguay and northwestern Argentina. There are six subspecies. One is occasionally treated as a separate species called the short-browed or brown spectacled owl but the consensus is that it is still merely a race until more detailed analysis can be done.
