Short-tailed Antthrush has a very wide geographic range, and so arguably is the best known species of Chamaeza antthrush. Nonetheless, almost all aspects of its natural history are unknown or very poorly known. The diet of Short-tailed Antthrush has not been described in any detail. The tolerance of this species to habitat disturbance or degradation has not been investigated. There is only limited information on the reproductive biology of this species, and no information on such topics as population density or population trends, age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality, and sexual behavior. Finally, Short-tailed Antthrush would benefit from a modern, comprehensive survey of geographic variation across its wide distribution.
