Upucerthia dumetaria ssp. peruana Zimmer

Peruvian Scale-throated Earthcreeper (Upucerthia dumetaria ssp. peruana)

The Peruvian Scale-throated Earthcreeper, one of three subspecies of the Scale-throated Earthcreeper (Upucerthia dumetaria I. Geoffroy Saint-Hilaire) (see photo), was described in 1954 based on two specimens that had been collected in the 1950s in the Puno region in the Andes of southern Peru.

The Peruvian Scale-throated Earthcreeper apparently was the largest of the three subspecies, reaching a size of about 21,5 cm, it is also said to have been darker colored than the other forms.

There are apparently no recent records of this form and it is sometimes thought to be already extinct, however, its type locality is huge and it might still be rediscovered some day. [1]
