A total of eight taxa were assigned to respective divergence events with confidence. Accounting for uncertainty, the number of taxon pairs for each divergence event is in parentheses.
Malurus splendens and Climacteris rufus were assigned with confidence to the second divergence event, and were analyzed alone, however the divergence event includes either Gliciphila melanops or Phylidonyris novaehollandiae, or both of these species (Psi = 3 (or 4)).
Ω very close to zero and Ψ = 1 indicates support for a single divergence event. A single divergence event for Malurus splendens and Climacteris rufus alone was not supported (Ψ = 2). A single divergence event for Malurus splendens, Climacteris rufus and Gliciphila melanops was not well supported, with Ω = 0.091 a significant outlier (P < 0.05).
