Evolution of arid zone birds in Australia: Leapfrog distribution patterns and mesic-arid connections in quail-thrush (Cinclosoma, Cinclosomatidae)

► We reconstruct a phylogeny of Cinclosoma using molecular markers. ► Multilocus gene and species trees support recognition of seven species. ► We infer that arid-adapted taxa evolved from forest-adapted ancestors. ► We investigate a 'leapfrog' distribution in plumage patterns. ► A hybridization event between C. castanotum and C. marginatum was identified.
