Some very special arrivals at Tower Hill are being put through their paces by their protective fathers. A number of chicks have been born - with a mother usually laying between six and 11 eggs in a clutch.
However, once she lays the eggs, it's up to the male to take over, according to a Parks Victoria spokeswoman.
"During the incubation period of roughly 60 days, the male will go without eating and drinking and will not leave the nest until the eggs are ready to hatch," she said.
"Young birds remain close to their dad for the next four months, learning from him what they can eat and the best places to find food. They are ready to leave his side at about six months of age and can start a family of their own at around 20 months."
Visitors to Tower Hill are asked to keep a respectful distance from the birds. "We also urge drivers on the roads around Tower Hill to be on the lookout for wildlife and reduce their speed," she said.
