  • The ostrich lays the largest egg which can weigh up to three pounds.
  • In brood-parasitism cases, the host bird will feed the intruder bird with its own brood, freeing up the real parent to forage and find food.
  • When lay egg ins, muscles contract the oviduct behind the egg, pushing it forward.
  • Later eggs in a clutch are sometimes more spotted as the female’s store of calcium is depleted.
  • Oology also includes the study of the breeding habits of birds and their nests.
