The curious type, which seems to be an exaggerated form of 

 3Ivscisaxkola, is also restricted to Patagonia and the Andes. It is 

 remarkable for the shortened tail and elongated hind claw, which 

 caused the older authors to refer it to Anthus, and it is said by 

 d'Orbigny and other authorities to be Lark-like in its habits. It 

 nests on the ground near the borders of streams.
