The International Ornithological Committee (IOC) and BirdLife International (BLI) recognize seven subspecies of tawny-faced gnatwren: Microbates cinereiventris semitorquatus Lawrence (1862) Microbates cinereiventris albapiculus Olson (1980)
Microbates cinereiventris magdalenae Chapman (1915) Microbates cinereiventris cinereiventris Sclater (1855) Microbates cinereiventris unicus Olson (1980) Microbates cinereiventris hormotus Olson (1980) Microbates cinereiventris peruvianus Chapman (1923)
However, the South American Classification Committee of the American Ornithological Society (SACC/AOS) and the Clements taxonomy have not accepted the three subspecies that Olson described but include them within M. c. peruvianus.
The tawny-faced gnatwren is 9 to 11 cm (3.5 to 4.3 in) long and weighs 10 to 14 g (0.35 to 0.49 oz). The nominate subspecies has a rusty face with a rufous crown and a thin black stripe behind the... Wikipedia →
