Discussion

• Body temperatures are guessed
• The high age at first reproduction cannot be captured by the std model
• mod_1: Pseudo-data point k is used, rather than k_J; Data set tp and parameter t_R are added, the latter replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
