Abstract

The encephalon of three tinamids: Eudromia elegans, Nothura maculosa, and Rhynchotus rufescens are quantitatively analized. Both relative volumes and cerebral indexes are calculated for eleven encephalic components. Results are discussed from an eco-ethological approach. The relative size of encephalic components in Eudromia, Rhynchotus, and Nothura indicate a close relationship among brain components and sorne behavioral patterns and the environment.
Marked differences in the cerebral organization of these tinamid genera are not evident. A greater development of the wu!st and low values ofolfactory bulbs suggest that Eudromia and Rhynchotus are progressive species. Nothura is considered primitive.
