Abstract

Little is known about the routes, timing and potential drivers of migration among austral migrants of South America. To contribute to a better understanding, we studied the migration of the southern subspecies of Rufous-collared Sparrow (Zonotrichia capensis australis) from the southernmost tip of South America. Based on 11 tracks, we found that departure from the breeding grounds in fall (post-breeding migration) occurred within a wide temporal window, beginning on March 22 and finishing on May 17. Wintering grounds were identified between 51.2° S and 31.9° S, within the Patagonian steppe ecoregion. Migration distance ranged from 450 to 2500 km, with the longest distance registered for two females who were the first to depart for the outbound route and the latest to arrive at the breeding grounds upon their return, offering an indication of a differential migration pattern.

期刊介绍： Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
