Ah ? Why ?

”Move Pinaornis from Muscicapidae to Turdidae. Phylogenetic analysis places it in a basal clade within Turdidae (Fjeldså et al. 2020)”

Must be something in press? Can’t find it.

Edit: oh, it must be in Largest Avian Evolution?

In fact, it's a book: The Largest Avian Radiation. The Evolution of Perching Birds, or the Order Passeriformes / [Eds] J. Fjeldså, L. Christidis & P.G.P.Ericson, Barcelona: Lynx Edicions , 2020

Thanks Björn

It would be interesting to get the reasoning for this. Clearly there is the desire to balance stability/tradition, presumably the reason for keeping Apodiformes when it was being lumped into Caprimulgiformes by most other authorities, and phylogenetic integrity, which made their paraphyletic Caprimuliformes untenable. But why have they taken the splitters approach and gone for six orders, five of them monotypic? They could have retained Aegotheidae within Apodiformes and placed Steatornithidae and Nyctibiidae in the same order (whichever has precedence) for a four order system that contained monophyletic groups and respected tradition. Is the split based on time of divergence or uncertainty of the the exact relationships?
 
From https://www.worldbirdnames.org/new/updates/taxonomy/ the relevant references

Order Caprimulgiformes Frogmouths, Oilbird, Potoos, NightjarsOrders Podargiformes, Steatornithiformes, Nyctibiiformes, CaprimulgiformesTAX, PHYSplit the broad and deeply divergent order Caprimulgiformes into four smaller orders (NACC 2016-A-10; SACC 703; Prum et al. 2015; Mayr 2014; Yuri et al. 2013; Chen et al. 2019).
Order Apodiformes Owlet-nightjars, Treeswifts, Swifts, HummingbirdsOrders Aegotheliformes, ApodiformesTAX, PHYSplit the nocturnal owlet-nightjars from the three diurnal familes in the order Apodiformes (NACC 2016-A-10; SACC 703; Prum et al. 2015; Mayr 2014; Yuri et al. 2013; Chen et al. 2019).

It basically boils down to 'These splits are very old'
