When animals put other animals in jail

Usually, it's humans putting animals in cages, but sometimes the animals do it to themselves.

Female platypus lock themselves in burrows to breed, great hornbill males lock females up in the hollow of a tree (they seal it up with fruit and poop) and potter wasps paralyse caterpillars for their babies to eat.

Today on What The Duck?!, Dr Ann Jones investigates the wild and hostile world of animal jails.

Are the animals just psycho killers or do they have their reasons?
