GOMEZ VILLAFANE, Isabel E.; MUSCHETTO, Emiliano  and  BUSCH, María. Movements of Norway rats (Rattus norvegicus) in two poultry farms, Exaltación de la Cruz, Buenos Aires, Argentina. Mastozool. neotrop. [online]. 2008, vol.15, n.2, pp.203-208. ISSN 0327-9383.

The aim of this work was to study the range of movements of Norway rats in two poultry farms in Exaltación de la Cruz, Buenos Aires Province. Three female and three male rats were followed by radio-telemetry. The mean home range was 0.024 ha (0.0024 to 0.0525 ha) and the mean maximum distance between localization points was 33.70 m (10 m to 66 m). The maximum daily movement registered was 65 m. Individuals captured near sheds or pigpens did shorter displacements than those captured on the perimeter of each farm. Our results indicate that Norway rats moved only short distances in poultry farms.
