Discussion
- Body temperatures are guessed
- food intake is given as function of time, but strange enough, it starts for 0, explaining why predicted growth is delayed, relative to observed, despite high v. Digestion efficiency is assumed to decrease slightly with specific feeding rate, relative to max
- life span seems very short for a macaw
- 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
Facts
- Female breeds, both parents feed young; nest in big hollow Caraibeira trees (Tabebuia aurea) (Ref: ADW, Wiki)
- Extinct in the wild (Ref: ADW, Wiki)
