Good babysitters are hard to find, so Mamma Cuckoos use some slight-of-wing to trick other birds into hatching and raising their young. They slip their eggs into the nests of smaller birds. When the Cuckoo chicks are born they knock those other eggs out of the way and convince their fake Mammas to feed them instead. It sure cuts down on childcare costs!
Wasp Mammas don’t need fancy bottle warmers or breastfeeding pillows. They make sure their babies have all the nourishment they’ll need ahead of time by paralyzing caterpillars and burying them alive with their wasp eggs. That way, the little wasp babies have plenty of fresh meat when they hatch. Yum!
