Park rangers at Pensthorpe Natural Park in Fakenham say they are 'tickled pink' after discovering flamingo eggs in their bird reserve.
Last year, twenty new flamingos were introduced to the previous flock of 29, with the hopes that they would begin to breed.
And now, for the first time in 15 years, flamingo eggs have been discovered on site.
The first egg was laid by a 14-year old female flamingo and has been now been carefully swapped for a wooden ‘dummy’ egg in order to protect it.
Since then, the birds have got the hang of it and more eggs have been found.
The eggs will be incubated and cared for by park staff to give it the best chance of survival.
Head of Species Management, Chrissie Kelley, said:
If all goes to plan, the egg will be returned to the nest shortly before hatching.
When hatched, flamingo checks are grey and do not reach the vivid pink colour the birds are known for until they are three years old.
