Discussion
- mod_2: v is reduced and food availability is taken variable in tW data
- 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
- This species is well known for its capacity to lower its body temperature during cold winter nights (Ref: Wiki)
