Kangaroo vs Cassowary

Kangaroo
Macropus rufus
Kangaroos cannot hop backward. The contract with physics is one-way.
Grasses and shrubs. They are hoppy lawn mowers.
Cassowary
Casuarius casuarius
Dads sit on the eggs and raise the striped chicks.
Mostly fruit. They are forest gardeners who accidentally plant trees with leftovers.
Who do YOU think wins?
