New notes on the nesting of some species of Northwestern Argentina birds

We present new dat on nesting of 12 bird species of the Yungas (montane forests ) of Salta and Jujuy provinces. We provide information on date, location, size, materials and contents of the nests. The nest and eggs of Atlapetes torquatus, apparently unknown, are described. Most avian species bred in the wet season, but Amazilia chionogaster nested in the dry season

The ecology and vocalisations of Banded Ground-Cuckoo Neomorphus radiolosus

El Cuco-Hormiguero Franjeado Neomorphus radiolosus es un ave rara, con problemas de conservación y cuya información sobre comportamiento y biología es deficiente. Cualquier dato adicional en este aspecto representa un instrumento importante para su conservación. Presentamos nuevos datos sobre su compartamiento en base a individuos observados en la Estación Biológica Jatun Sacha Bilsa, Esmeraldas, Ecuador, y la Reserva El Pangan, Nariño, Colombia

New records of <i>Catamblyrhynchus diadema</i> for Northwestern Argentina

The first record of the Plushcap ( <i>Catamblyrhynchus diadema</i>) for Salta province is given based in a collected specimen. New records for Jujuy province are reported. A immature plumage is described and information about the habits is discussed by means ofthe bibliography and field notes

The prescence of Pseudocolopteryx citreola in eastern Argentina, with comparisons of voice with other doraditos

The Ticking Doradito (Pseudocolopteryx citreola) was included in P. flaviventris until a recent taxonomic revalidation. The plumages of the two species are virtually indistinguishable and so recording their vocalizations is necessary in order to identify the species with any certainty. In Chile P. citreola is found in the centre of the country and it is a migrant but its winter distribution is unknown. In Argentina the situation is more complicated as it is possible to find this species and P. flaviventris in the same areas. In Argentina P. citreola occurs in the foothills of the Andes from Río Negro to Salta and it even reaches low lying areas in Bolivia. We present the first two recordings of P. citreola vocalizations for the eastern sector of the Southern Cone (one from eastern Entre Ríos and the other from southwestern Buenos Aires province, Argentina, both in November). We comment on potential confusions created by our new data in reference to the distribution of P. flaviventris in the Cisandean region. Possibly our new records of P. citreola records represent a west-east migration pattern. A phonetical comparation and sonograms showing the differences between the song of this species and the other Pseudocolopteryx is presented. The voices of P. citreola resemble those of P. dinellianus and (to a lesser extent) those of P. acutipennis, and are markedly different from those of P. flaviventris. The voices of P. citreola in Salta province, northwestern Argentina, are somewhat different from those elsewhere, and merit further research.Fil: López Lanús, Bernabé.
