Figure 4. A. Estimates of speciation and extinction rates from HiSSE and MuSSE analyses (RevBayes) for four states of nest type/thermal range combination, using the MCC tree. B. Transition rates between the four states presented in panel A, from the analysis on the MCC tree using RevBayes (HiSSE). Numbers in parentheses represent the 95% confidence intervals of the rates. Orange arrow in the back represents most likely path, from the most probable ancestral state (domed nest/narrow niche) to the derived and most common condition (open/wide).
