Austral Canastero
Asthenes anthoides
Ranging further south into cooler, wetter Patagonian habitat than several of its canastero relatives, an austral canastero weaves the same distinctive domed stick nest shared across the wider canastero group.
Overview
The austral canastero, Asthenes anthoides, is a Least Concern bird native to grassland and forest habitat across southern Chile and Argentina. Its tolerance for cooler, more southerly conditions than several canastero relatives, its distinctive domed nest, and its flexibility between open scrub and forest edge make it one of the more adaptable small ovenbirds found anywhere in Patagonia.
A canastero that pushed further south
While several canastero relatives stay confined to drier, more northerly scrub, the austral canastero instead extends its range into the cooler, wetter conditions of southern Patagonia, adapting its habitat use between open ground and forest edge along the way.
Status
Least Concern, remaining widespread and generally stable across suitable grassland and forest-edge habitat in southern Chile and Argentina.
