Chats (formerly sometimes known as"chat-thrushes") are a group of smallOld World insectivorousbirds formerly classified as members of thethrush family (Turdidae), but following genetic DNA analysis are now considered to belong to theOld World flycatcher family (Muscicapidae).[1]
The name is normally applied to the more robust ground-feeding flycatchers found inEurope andAsia and most northern species are strongmigrants. There are many genera and these birds in particular make up most of thesubfamilySaxicolinae.
Other songbirds called "chats" are:
Australian chats, generaAshbyia andEpthianura of the honeyeater family (Meliphagidae). They belong to a more ancient lineage than Saxicolinae.
American chats, genusGranatellus of the cardinal family (Cardinalidae), formerly placed in the wood-warbler family. They belong to a more modern lineage than Saxicolinae.
Yellow-breasted chat (Icteria virens), an enigmatic North American songbird previously placed in the wood-warbler family (Parulidae) and now in the monotypic Icteriidae; its true relationships are unresolved.
Thecladogram below is based on amolecular phylogenetic study by Min Zhao and collaborators that was published in 2023. Some regions of the phylogenetic tree were not strongly supported by the sequence data.[8] Both the genera included and the number of species in each genera are taken from the list of birds maintained byFrank Gill,Pamela C. Rasmussen and David Donsker on behalf of theInternational Ornithological Committee (IOC).[1]
