Several bird species follow legions of ants in order to feed on the arthropod fauna that flees from these swarms. Most of these birds are opportunistic, while a few are obligate or specialist followers. These interactions between ant swarms and birds have been widely documented in lowland tropical areas, but in the highlands of the Neotropics, this phenomenon is poorly understood. In this note, we present the analysis of an interaction event between a group of birds (Grallaria milleri, Arremon assimilis, Scytalopus spillmanni) and an ant swarm possibly of the genus Neivamyrmex, in the Río Blanco Reserve (Manizales-Caldas). This is the first report of S. spillmanni and the second of G. milleri and A. assimilis following an ant swarm, in addition, we include a review of other reports of birds following legionary ants in the Colombian Andes.
