Notes on the nesting of 20 species of Northwestern Argentina birds

Abstract

We present data on nesting of 20 bird species of the Yungas (montane forests) of Salta and Jujuy provinces. We provide information on date, location, shape, size, materials and contents of the nests. Breeding information is presented for the little-known nest of Sittasomus griseicapillus, Poecilurus scutatus, Syndactyla rufosuperciliata, Todirostrum plumbeiceps and Contopus fumigatus. Chicks in a nest of Cliff Flycatchers Hirundinea ferruginea were fed by three adults. Helpers were detected in nests of Plush-capped Jays Cyanocorax chrysops. Most avian species bred principally in the wet season, but the Hermit Hummingbird Phaethornis pretrei nested in the dry season.
