Typical Owls (Strigidae)
Ferruginous Pygmy-owl (Glaucidium brasilianum) - HBW 5, p. 217
French: Chevêchette brune
German: Brasilzwergkauz
Spanish: Mochuelo Caburé
Taxonomy: Strix brasiliana J. F. Gmelin, 1788, Ceará, Brazil.
Considered by some authors to form superspecies with G. tucumanum, G. peruanum and G. nanum. Has been considered to include those as races, but recent studies have shown all to be vocally distinct and to differ in DNA. In past treated as conspecific with G. jardinii, but again differs in vocalizations and DNA. N populations (cactorum, ridgwayi, saturatum) recently proposed as forming separate species (G. ridgwayi); further study needed. Race pallens perhaps better placed in G. tucumanum. Twelve subspecies recognized.
