All chicks are born with white plumage, which they keep for around three years, and a straight bill, which gradually droops down as they grow.
Keeper, Lauren Hooper-Bow said: “We are extremely pleased with the high hatching success rate among the flamingos this year.
“With the number of eggs still to hatch, it could be our best year to date and it’s particularly welcome as in 2019 heavy snow showers prevented the flamingos from sitting on any of their eggs.
“This year’s success is likely to be down to a combination of factors including good weather during the egg hatching period, having a large colony and the fact so many of the eggs were fertile,” she added.
Flamingos lay a single egg on top of a tall cone nest.
When they are fully grown the flamingos stand at around a-metre-and-a-half tall, and can weigh anywhere up to seven kilograms.
They live 15-20 years in the wild, however in captivity, and safe from natural predators, the Chilean birds can reach ages of 70-years-old.
Chilean flamingos can survive at high altitude in the Andes Mountains, which run from Venezuela in the north and the range passes through Colombia, Ecuador, Peru, Bolivia, Argentina and Chile.
They are also significantly more able to deal with the cold than their Caribbean counterparts.
In the wild, flamingos eat small crustaceans and other microscopic animals and plants, which are obtained by filter feeding.
When adult, the continuously-moving beak acts as an efficient filter for food collection when water is pumped through the bristles of the mouth.
The flamingos’ famous pink plumage comes from pigments in their diet which is replicated in their special feed at Longleat.
