Avistamientos de <i>Cinclus schulzi</i> en la Cordillera de Sama, Bolivia
(2015) Eliana Flores Bedregal; Orlando Herrera Carrasco; José M. Capriles
We present sighting data of the Rufous-throated Dipper (Cinclus schulzi) in Cordillera de Sama, Tarija Department, Bolivia. We visited 17 rivers and streams, but we attained only 12 sightings in 4 water courses, corresponding to a minimum of 10 individuals: 4 pairs, a solitary individual and a fledging. Dippers were recorded in clear water courses, but were absent in sites contaminated with livestock waste. We confirm the presence of Cinclus schulzi in the Cordillera de Sama Biological Reserve and its nesting in the area. Furthermore, we present data about foraging behaviour and interactions with other species.
Pre-Columbian transregional captive rearing of Amazonian parrots in the Atacama Desert

The feathers of tropical birds were one of the most significant symbols of economic, social, and sacred status in the pre-Columbian Americas. In the Andes, finely produced clothing and textiles containing multicolored feathers of tropical parrots materialized power, prestige, and distinction and were particularly prized by political and religious elites. Here we report 27 complete or partial remains of macaws and amazon parrots from five archaeological sites in the Atacama Desert of northern Chile to improve our understanding of their taxonomic identity, chronology, cultural context, and mechanisms of acquisition. We conducted a multiproxy archaeometric study that included zooarchaeological analysis, isotopic dietary reconstruction, accelerated mass spectrometry radiocarbon dating, and paleogenomic analysis. The results reveal that during the Late Intermediate Period (1100 to 1450 CE), Atacama oasis communities acquired scarlet macaws (<i>Ara macao</i>) and at least five additional translocated parrot species through vast exchange networks that extended more than 500 km toward the eastern Amazonian tropics. Carbon and nitrogen stable isotopes indicate that Atacama aviculturalists sustained these birds on diets rich in marine bird guano-fertilized maize-based foods. The captive rearing of these colorful, exotic, and charismatic birds served to unambiguously signal relational wealth in a context of emergent intercommunity competition.
