Laughingthrushes are passerine family of mostly Old World birds (Cibois et al., 2018). They were formerly included in the Timaliidae. Hybridization has been reported in three genera, Turdoides, Garrulax and Actinodura. But captive hybrids of Minla and Leiothrix are also known.
One study suggested extensive gene flow during the divergence between Chinese Hwamei (G. canorus) and Taiwan Hwamei (G. taewanus) using ABC modelling (Li et al., 2010). Post-divergence introgression was also detected between two Black-throated Laughingthrush subspecies (G. chinensis chinensis and G. c. lochmius) on Hainan Island (Wu et al., 2012).
