Typical Owls (Strigidae)
Tawny-bellied Screech-owl (Otus watsonii) - HBW 5, p. 179
French: Petit-duc de Watson
German: Watsoneule
Spanish: Autillo del Amazonas
Other common names: Austral/Southern Screech-owl (usta)
Taxonomy: Ephialtes Watsonii Cassin, 1848, Orinoco River, Venezuela.
Suggested to belong to the O. atricapillus superspecies, but large overlap in range with O. vermiculatus. From vocal evidence and DNA sequencing appears closest to O. atricapillus; more distantly related to O. choliba than previously thought. Race usta has been treated as separate species; compared with nominate, however, differences in morphology appear to be minimal and vocal dissimilarities probably not constant; also, their ranges may partly overlap. Two subspecies recognized.
Subspecies and Distribution:
- watsonii (Cassin, 1848) - lowlands from E Colombia S to NE Peru and E (N of R Amazon) to Surinam and Amazonian Brazil.
- usta (P. L. Sclater, 1859) - E Peru and S Amazonian Brazil S to lowland forest of N Bolivia and N Mato Grosso.
