This contribution provides information, obtained during an uninterrupted period between June 1977 and October 1981, regarding the behavior, distribution and taxonomy of 36 species of marsh and lowland rainforest birds in the department of Madre de Dios (and the most frequently mentioned locality is the TRZ). Most of these birds are little-known residents of the forest, though some are of wide distribution and common in other regions, occuring only as migrating or errant birds in Peru. Data on the specimens of poorly known species is included, and the first recordings in Peru of the following species are reported: Chauna torquata, Porphyrula flavirostris, Coccyzus cinereus, Sinallaxis albescens, Myrmotherula iheringi, Myiozetetes cayanensis, Catharus fuscescens and Oporornis agilis. The following species, known from 10 specimens or less, are also considered: Simoxenops ucayalae, Myrmeciza goeldii and Poecilotriccus albifacies. The collections carried out have demonstrated that the ant-eating bird (Formicariidae) described as Percnostola macrolopha is in reality the male of Percnostola lophotes and not a separate species. A range of resident species, including Dryophila devillei and Ramphotrigon megacephala, are definitely associated with bamboo habitats (Guadua sp.). The small proportion of the birdlife comprising southern migratory birds include species such as Coccyzus cinereus, Satrapa icterophrys, Casiornis rufa, Pseudocolopteryx acutipennis, Inezia inornata and Turdus amaurochalinus.
