The discovery of Dwarf Tinamou Taoniscus nanus in Bolivia, with additional notable records from the country

Abstract

We provide new information on the status, occurrence and ecology of birds in Bolivia. Although we focus on discoveries made during recent (2024) field work, several records overlooked from previous field work are mentioned herein. We present the first evidence of Dwarf Tinamou Taoniscus nanus in Bolivia, approximately 1,500 km from its nearest known population in Goiás, central Brazil. We confirm the presence of Cryptic Flatbill Rhynchocyclus (olivaceus/aequinoctialis) cryptus in the country and argue that Eastern Olivaceous Flatbill R. (o.) guianensis is also likely to occur in easternmost Bolivia. Four new species for Beni (Rufous-thighed Kite Harpagus diodon, Lowland Hepatic Tanager Piranga flava, Pied Puffbird Notharchus tectus, Cliff Flycatcher Hirundinea ferruginea) are reported and one new species for Oruro (Great Kiskadee Pitangus sulphuratus).
