Here we documented up-to-date information on breeding ecology of Buffy Laughingthrush (Garrulax berthemyi), an endemic species of China, and a sympatric coordinal Red-tailed Laughingthrush (Trochalopteron milnei), in southwestern China. Furthermore, we compared breeding ecology of these two sympatric species. No significant differences were found in clutch size, egg size, nest size, nest height, nest habitat and predation rate between these two species except nests depth, nests cover and eggs color. The Red-tailed Laughingthrush nestlings differed from those of the Buffy Laughingthrush in gape morphology and the extent of down. Observation of breeding behavior showed that cooperative breeding might exist in the population of Buffy Laughingthrush.
