Discussion

  • body temperature is guessed
  • males are assumed not to differ from females
  • mod_1: data added: tW1, Ww0
  • 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

  • uses urohidrosis, defecating on its legs, to lower its body temperature; lacks a voice box (Ref: Wiki)
