Abstract
ABSTRACT Crypturellus duidae (Tinamidae) is a poor-soil specialist with isolated populations in Amazonia, and is considered restricted to white-sand forest habitats. We report the first record of C. duidae in a peatland forest in northern Peru, in the Putumayo River basin. Our record extends the known distribution of C. duidae between two disjoint areas of occurrence in Peru and Colombia, and shows its presence in peatland forest, another forest type on nutrient-poor soils. Additionally, we report the presence of other poor-soil specialist bird species that were previously registered in peatlands. Together with the new record of C. duidae, these bird records provide evidence of the diversity of poor-soil specialists in peatland forests.
Highlights
Primer registro de la perdiz de pata gris, Crypturellus duidae, y otras aves especialistas de suelos pobres en turberas en la cuenca del Río Putumayo, Loreto, Perú
In the Loreto region, in the northern Peruvian Amazon, white-sand forests are a distinctive collection of forest types characterized by high stem densities, a canopy as low as 5 m (GarcíaVillacorta et al 2003), and a distinctive floristic assemblage dominated by specialist trees (Zárate et al 2015)
In addition to being the first record of C. duidae from a peatland forest, this is the first record of the species in Peru far from white sand and its known occurrence areas in the upper Nanay River basin in Peru and in the Chiribiquete region of Colombia (Álvarez et al 2003)
