THE pressure is on for Cooberrie's canoodling cassowaries to keep on doing what comes naturally.
For there's already a list of zoos waiting for Punch and Judy to produce more chicks like Berrie to help preserve one of the world's most critically endangered species.
Berrie flew the coup last week, leaving her keeper Francis Carnahan who hand-raised her from the moment she cracked through her egg about 15 months ago.
The chick has been sent to Brisbane's Alma Park Zoo where she will be part of a new breeding program.
And her siblings, Franny and Hammy, have left the wildlife sanctuary for Victoria's Halls Gap Zoo where it's hoped they will eventually produce their own offspring.
Cooberrie Park's cassowary enclosure is currently the world's largest display facility for southern cassowaries at more than two acres with a lush rainforest and natural creek.
The sanctuary has the best breeding record in Australia thanks to Punch and Judy, and if they have more chicks they will go to zoos in Western Australia and southern Queensland.
