Abstract

Catharus ustulatus (Nuttall, 1840) (Swainson’s Thrush), a long-distance migratory songbird, spends its nonbreeding period primarily in northwestern South America and has been listed hypothetically in Paraguay. Here, we provide the first confirmed record of the species in Paraguay, documented by photographs. This find extends the known range of C. ustulatus into the Dry Chaco ecoregion, with potential implications for understanding this species’ nonbreeding distribution and habitat use.
