There are 15 flamingos at the park, the only ones in Cornwall.
Young flamingos are grey and slowly develop a pink colouring by consuming crop milk from their parents and eating types of algae, crustaceans and insect larvae.
Mr Reynolds added Frankie could be at risk from foxes and “hopefully she found somewhere safe to stay last night”.
“We need to get her back as soon as possible. If she’s in water then she’s ok but up on the land, you know it’s very worrying for us.”
Anyone who sees a flamingo in the area is asked to immediately contact Paradise Park and staff will attempt to rescue her.
