Discussion
- Length at birth is ignored, because tail and bill contribute a lot to length and they are born naked with a short bill
- mod_1: v is reduced and food availability in tW taken variable
- mod_2: 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
- Body temperature drops at night (Ref: Wiki)
