Parrotbills & Allies - Paradoxornithidae

Bird family - Paradoxornithidae is sister to Sylviidae but is deeply divided from it to a degree that is similar to other families in the babbler radiation. Recognize as a separate family (Cai et al. 2019). Sequence and constituent species of the entire family is based on Cai et al. (2019). Alteration of the generic taxonomy of the parrotbill group, per se, with its reduction from nine to only two genera, formerly based on Penhallurick & Robson (2009), is revised to also follow Cai et al. (2019) in 13.2.
