Discussion
- males are assumed to differ from females by {p_Am} only
- food intake varies somewhat in time
- mod_1: v is reduced
- mod_2: males have equal state variables at b, compared to females
- mod_3: 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
