Discussion
- Males are assumed to differ from females by {p_Am} only
- Till day 151 or 155, weights are predicted by JackFisk1998, not measured
- food intake till weaning is assumed to be higer than post-weaning
Facts
- strong body size gradient from small in NE to large in SE Australia (Ref: Kooy2010)
- sensitive electroreception in bill; males have no parental care; hatching young are blind, without hair and fed with milk; after 5 w since birth, mother start spending time outside the burrow; after 4 m since birth, young emerge from burrow (Ref: Kooy2010)
