New sites and range extensions for endemic and endangered birds in extreme north-east Brazil

摘要

Between 1998 and 2011 we surveyed diverse localities within the Atlantic Forest and Caatinga biomes in the north-east Brazilian state of Rio Grande do Norte, registering the presence of Ochraceous Piculet Picumnus Ulnae, Silvery-cheeked Antshrike Sakesphorus cristatus and Yellow-faced Siskin Sporagra yarrellii, none of which had definitely been recorded previously in the state. We also present new records of Tawny Piculet Picumnus fulvescens, expanding our knowledge of the species' distribution.
