KLAVINS, Juan  and  BODRATI, Alejandro. The Masked Water-Tyrant (Fluvicola nengeta): a new species for Paraguay, and second record for Argentina. Hornero [online]. 2007, vol.22, n.1, pp.43-45. ISSN 0073-3407.

The Masked Water-Tyrant (Fluvicola nengeta) occurred historically in northeastern Brazil. In recent decades, its range has expanded to the south and west, reaching the states of southeastern Brazil, where it previously did not occur. We present the first record for Paraguay and the second record for Argentina, which further extend the species' distribution. Our observations support the opinion that the species is in expansion, being favoured by human habitat alteration. Additionally, we support the use of Viudita Enmascarada as a common name in Argentina and Paraguay.

Keywords : Argentina; expansion; Fluvicola nengeta; Masked Water-Tyrant; new record; Paraguay.
