Quebracho Crested-Tinamou is a Chaco endemic and is restricted to a small area of western Paraguay, southeastern Bolivia and northern Argentina, where it inhabits dry thorny woodland and adjacent savanna in arid areas. The ecology of this species is poorly known, but initial field observations suggest considerable similarities between it and the more widespread and well-studied Elegant Crested-Tinamou (Eudromia elegans) with which it forms a superspecies. It differs from that species principally in the browner dorsal coloration, bolder markings on the breast, and less heavily-marked underparts. The subspecies E. f. mira, described for Paraguayan populations, is dubiously valid and most modern authorities consider the species monotypic. Quebracho Crested-Tinamou currently is not considered to be under any conservation threat, but accelerating habitat loss within the species range means that it may qualify for threatened status in the near future.
