Lincoln Park Zoo Has Flamingo Eggs

A female Chilean flamingo tends to two eggs on July 16 while Lincoln Park Zoo staff anxiously hold their collective breath in anticipation for flamingo chicks. This is the first time in the zoo's 140-year history that their flamingo flocks have laid eggs. For a flamingo to incubate not only one egg, but two, is particularly unusual. 

Incubation is approximately 4 weeks, so if all goes well, chicks should be hatching in late July and early August.

Chilean flamingos are a gregarious species of flamingo native to South America.  Their conservation status is listed as near threatened and in need of protection.

Phoenicopterus chilensis

Birds
Order:   Ciconiiformes

Description
With tall, thin legs and a long, flexible neck, the Chilean flamingo can reach up to 40 inches in height. Like all flamingos, it has striking pink plumage, including crimson highlights along the edges of the wings. What appears to be the bird’s knee is actually its ankle—the joint bends backward rather than forward.

Range
Peru and Brazil south to Argentina

Status
Not threatened

Habitat
Coastal mudflats, estuaries, lagoons and salt lakes. Chilean flamingos can occupy habitats ranging from sea level up to 14,000 feet in the Andes. Their ability to tolerate extreme conditions makes them well suited for Chicago’s harsh winters.

Niche
The Chilean flamingo’s bill is equipped with comb-like structures that enable it to filter food—mainly algae and plankton—from the water.

Life History
Chilean flamingos live in large flocks in the wild and require crowded conditions to stimulate breeding. During breeding season, males and females display a variety of behaviors to attract mates, including head bobbing—swiveling their heads from side-to-side in tandem—and wing salutes, where the wings are repeatedly opened and closed. Males and females cooperate in building a pillar-shaped mud nest, and both incubate the egg laid by the female. Upon birth, the chicks have gray plumage; they don’t gain adult coloration for two–three years. Both male and female flamingos can produce a nutritious milk-like substance in their crop gland to feed their young.
