The encephalon of three tinamids: Eudromia elegans, Nothura maculosa, and Rhynchotus rufescens are quantitatively analyzed. Both relative volumes and cerebral indexes are calculated for eleven encephalic components. Results are discussed from an eco-etiological approach. The relative size of encephalic components in Eudromia, Rhynchotus, and Nothura indicate a close relationship among brain components and some behavioral patterns and the environment. Marked differences in the cerebral organization of these tinamid genera are not evident. A greater development of the wulst and low values of olfactory bulbs suggest that Eudromia and Rhynchotus are progressive species. Nothura is considered primitive.
对三种䳍形目鸟类（优雅凤头䳍、斑胁田鸡和红嘴䳍）的脑进行了定量分析。计算了11个脑区的相对体积和脑指数。从生态病因学角度对结果进行了讨论。凤头䳍属、红嘴䳍属和田鸡属鸟类脑区的相对大小表明，脑区组成与一些行为模式及环境之间存在密切关系。这些䳍形目属种在脑组织结构上的显著差异并不明显。脑嵴的较大发育和嗅球的低值表明凤头䳍属和红嘴䳍属是进化的物种。田鸡属被认为是原始的。
