FRAGA, Rosendo; JORDAN, Emilio A.; DARDANELLI, Sebastián  e  FIGUERERO, Carlos. COLONIZATION OF THE ARGENTINEAN MESOPOTAMIA BY CHACO CHACHALACA (ORTALIS CANICOLLIS). Hornero [online]. 2021, vol.36, n.2, pp.120-129. ISSN 0073-3407.

We report information from museum specimens, online databases, bibliographic records, and field data that show colonization of the Argentinean provinces of Entre Ríos and Corrientes (Argentinean Mesopota-mia) by Chaco Chachalacas (Ortalis canicollis). This colonization probably started during the first decades of the 20th Century, and this cracid is currently expanding its range towards the Uruguay River basin.

Palavras-chave : Biogeographical barriers; Cracidae; Historical data; Paraná River; Range expansión.
