Cladogram for Neognathae, which includes 71 of the 83 species and 46 of the 49 families used in this study. Calibration of branches (in Myr) and the basal relationships up to the family level followed to Prum et al. (2015). Clade colours also are coded as Prum´s paper: red – Galloanserae; brown – Strisores; purple – Columbaves; yellow – Gruiformes; blue – Aequoritornithes; green – Inopinaves. Intraclade relationships that could not be established and calibrated in our dataset using Prum et al. (2015), were resolved using the specific references indicated by the numbers nearby corresponding clades: 1 – Columba (Jetz et al. 2012); 2 – Rallidae (García-R et al. 2014); 3 – Laridae (Jetz et al. 2012); 4 – Alcidae (Pereira et al. 2008); 5 – Sulidae (Patterson et al. 2011); 6 – Accipitridae (Jetz et al. 2012); 7 – Picidae (Jetz et al. 2012); 8 – Alcedinidae (Jetz et al. 2012); 9 – Psittacidae (Braun et al. 2011); 10 – Cacatuidae (White et al. 2011); 11 – Corvoidea (Kennedy et al. 2012); 12 – Artamidae (Jetz et al. 2012); 13 – Alaudidae (Jetz et al. 2012); 14 – Turdidae (Nylander et al. 2008).
