Typical Owls (Strigidae)
Eastern Screech-owl (Otus asio) - HBW 5, p. 174
French: Petit-duc maculé
German: Ostkreischeule
Spanish: Autillo Yanqui
Other common names: Common Screech-owl
Taxonomy: Strix Asio Linnaeus, 1758, South Carolina.
Sometimes considered to form superspecies with O. kennicottii, O. seductus and O. cooperi. Formerly treated as conspecific with O. kennicottii, and may interbreed in areas of range overlap (separated by 60 km in Oklahoma “panhandle”, slightly sympatric in Colorado Springs, broadly overlapping inTexas, undetermined in Mexico), but vocal and DNA analyses indicate that treatment as separate species more appropriate. Often considered to include O. seductus and O. cooperi as races. Geographical limits of listed races require further study; naevius<.. View all taxonomy...
Sometimes considered to form superspecies with O. kennicottii, O. seductus and O. cooperi. Formerly treated as conspecific with O. kennicottii, and may interbreed in areas of range overlap (separated by 60 km in Oklahoma “panhandle”, slightly sympatric in Colorado Springs, broadly overlapping inTexas, undetermined in Mexico), but vocal and DNA analyses indicate that treatment as separate species more appropriate. Often considered to include O. seductus and O. cooperi as races. Geographical limits of listed races require further study; naevius sometimes merged with nominate. Additional described races probably reflect individual variation or intermediates only: swenki of SC Canada to Oklahoma included in maxwelliae; semplei from C Mexico in mccallii. Six subspecies recognized.
