Discussion

  • Growth fit assumes constant feeding, rather than 3 feeding events

Facts

  • Strictly haematophagous on birds; 3 feeding events are required to reach maturity (Ref: Land1983)
  • Urine excretion contributes substantialy to weight loss between meals (Ref: Land1983)
  • Broods its embryos on the ventral surface; does not feed as adult, but mother attaches to host for the first feeding of the young (Ref: Wiki)
