Life history data table formatted for input into the Coevol analytical software. Life history data were obtained from the AnAge senescence database Build 13 (De Magalhães, J.P. and Costa, J. 2009, Tacutu, R., Craig, T., et al. 2013). We collated the following data: (1) age at sexual maturity (days), (2) incubation time (days), (3) number of eggs laid per year, (4) mass at hatching (grams), (5) growth rate (1/days), (6), maximum recorded longevity (years), and (7) total metabolic rate (watts). Relative to the set of 198 avian taxa in (Prum, R.O., Berv, J.S., et al. 2015), when matching genera occurred in the AnAge database, we used averages at the genus level; otherwise, we used family-level averages. Body mass (grams, species average) data were collected from Dunning Jr, J.B. (1992). This yielded a data matrix with ~49% missing data overall (with no missing data for body mass).
