We present new records of the little- known White- chested Swift Cypseloides lemosi from northern Peru and north- west Bolivia; photographic documentation is available for one of the Peruvian records, whilst the sight- only Bolivian records represent the species’ first mention for the country. We also present a photographically documented record of the almost equally poorly known White- chinned Swift C. cryptus from north Peru, along with two previously unpublished specimen records from the same country, and discuss some aspects of the identification of both these swifts.
