These olivaceous flycatchers are very similar in coloration, the trans-Andean R. brevirostris being darker green above and deeper yellow below than the Amazonian R. olivaceus. Note the occurrence of R. brevirostris on mountains in eastern Panama above the lowland forest habitat occupied by R. olivaceus. Modified from Haffer (1967 b).
