Absolute rate of diversification for the entire birds-of-paradise clade, core (polygynous) birds-of-paradise, some closely related families, and core Corvoidea, estimated in absence of extinction (ε = 0) and comparatively high (ε = 0.90) relative extinction rate. The 95% confidence intervals at relative extinction rates of ε = 0 and ε = 0.90 are expressed as expected number of species for each clade. The 95% confidence intervals have been calculated as described by Magallon and Sanderson [Magallon and Sanderson 2001] and is based mean diversification rate for the core Corvoidea (at a relative extinction rates of ε = 0 and ε = 0.90) and the age of the clades.
