Discussion
- males are assumed to differ from females by {p_Am} only
- nestlings exceed mean adult weight at day 10 for males and 11 for females; f > 1 had been allowed to accomodate this pattern
- body temperature has been guessed
- mod_1: v is reduced and food availability is taken variable in tW data
- mod_2: males have equal state variables at b, compared to females
- mod_3: 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
Facts
- Helpers for caring nestlings are frequently around (Ref: Sher1985)
- Males spend half as much time in incubation than females, spend equal time in brooding nestlings (12 d period), but contribute more to feeding nestlings; (Ref: Sher1985)
