Resumen

El nido del Hornero (Furnarius rufus) se caracteriza tanto por su conspicuidad como por la fortaleza de su construcción, que presumiblemente sirve como defensa contra depredadores. En este registro reportamos por primera vez la rotura del nido y depredación de un pichón de Hornero por parte de un Carancho (Caracara plancus). La depredación del nido, ocurrida luego de que lloviera, sugiere que los caranchos pueden depredar oportunistamente sobre nidos de Hornero debilitados por las lluvias.
