Résumé :	Birds in Neotropical forests frequently follow army ants to forage for insects. 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.
