- Resumen:
- The Hellmayr’s Pipit ( Anthus hellmayri
) is a poorly known species distributedthrough southern South America. It is represented by three subspecies; one of them, A. h. dabbenei
,is considered migratory. Although it is believed that A. h. dabbenei is migratory in Chile, there is insuffi-cient evidence to its status. In the period between 2010 and 2011 we conducted an exhaustive searchfor this species in the Araucania Region of south-central Chile. In addition, historical and previousrecords by the authors were included in the analysis. In total, we recorded 57 individuals from sea levelto 1400 m a.s.l., found in the period between September and March in the years 2003–2011. Thesefindings support what appears to be regular migratory behavior of a summer resident species in Chile,not a vagrant as suggested by previous works. The habitats used in Chile are similar to those reportedin Argentina and Uruguay, and can be categorized as grasslands dominated by annual plants, and withthe presence of isolated shrubs. We also discuss reproduction and seasonality of Hellmayr’s Pipit inChile.
