Page "Chilean Flamingo" Paragraph 5

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 flagging — 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.
