Systematics
This article follows the Handbook of Birds of the World in including the small chat-like ground feeders previously classed with the Turdidae thrushes in this group. Recent biochemical studies found certain traditional thrush genera (Monticola, Myiophonus, Brachypteryx, and Alethe) here in the Muscicapidae. Conversely the Asian saxicoline genera Grandala and Cochoa belong among the thrushes, however this is disputed.
The division of Muscicapidae into two subfamilies may be artificial. Some genera in one subfamily are closer to members of the other and vice-versa. As the exact relationships of the family's members are worked out the internal taxonomic structure of the family may need to be radically revised.
