Tailorbirds are small birds, most belonging to the genus Orthotomus. While they were often placed in the Old World warbler family Sylviidae, recent research suggests they more likely belong in the Cisticolidae and they are treated as such in Del Hoyo et al.[2] One former species, the mountain tailorbird (and therefore also its sister species rufous-headed tailorbird), is actually closer to an old world warbler genus Cettia.[3]
