Here we report the first record of several species of Neotropical grassland birds following army ants (Labidus praedator) and yellow armadillos (Euphractus sexcinctus). We observed Strange-tailed Tyrants (Alectrurus risora) following army ants in El Bagual Ecological Reserve in Argentina. Other species also observed following army ants included Pampas Finches (Embernagra platensis), Wedge-tailed Grass-finches (Emberizoides herbicola), Long-tailed Reed-finches (Donacospiza albifrons), Great Kiskadees (Pitangus sulphuratus), Rufous Horneros (Furnarius rufus), Gray Monjitas (Xolmis cinerea), and Pale-breasted Spinetails (Synallaxis albescens). Strange-tailed Tyrants and Wedge-tailed Grass-finches were also observed following armadillos. Because birds were observed capturing insects flushed by the army ants and armadillos, our observations indicate that birds that opportunistically follow army ants and armadillos benefit from the association. SINOPSISes Las aves de selva del Neotrópico a menudo siguen a las hormigas legionarias para alimentarse. Aquí reportamos por primera vez algunas especies de aves del pastizal Neotropical siguiendo a las hormigas legionarias (Labidus praedator) y a los armadillos (Euphractus sexcinctus). En la Reserva Ecológica El Bagual, provincia de Formosa, Argentina (26°11′S–58°57′W) registramos mayormente al Yetapá de Collar (Alectrurus risora). Otras especies registradas realizando el mismo comportamiento fueron Verdón (Embernagra platensis), Coludo Grande (Emberizoides herbicola), Cachilo Canela (Donacospiza albifrons), Benteveo Común (Pitangus sulphuratus), Hornero (Furnarius rufus), Monjita Gris (Xolmis cinerea) y Pijuí Cola Parda (Synallaxis albescens). También registramos al Yetapá de Collar y al Coludo Grande siguiendo armadillos. Debido a que las aves fueron observadas capturando insectos espantados por las hormigas y los armadillos, nuestras observaciones indican que las aves de pastizal podrían beneficiarse de dicha asociación.
