Discussion
- Time between clutches at T is 182.5 days, similarly to some other members of the Icteridae family present in the database; this value is used as parameter t_N (not estimated)
- Males differ from females in zoom factor only
- mod_1: v is reduced; food availability taken variable in tW data
- 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
