1. They are born dull gray, not bright pink! Baby flamingos hatch with fluffy gray or white feathers. They only turn pink after a few years of eating special foods like algae and brine shrimp.

2. They eat upside down. When a flamingo wants to eat, it ducks its head into the water upside down! Its curved beak acts like a sieve, pumping water out while trapping tiny shrimp, bugs, and seeds inside its mouth.

3. Standing on one leg saves energy. Flamingos often sleep and stand on just one leg. Scientists discovered that their leg joints lock into place, taking almost zero muscle power to stay balanced without falling over!

4. Their "knees" are actually ankles. The bendy joints in the middle of a flamingo's long legs look like knees that bend backward, but they are actually their ankle joints! Their real knees are tucked up high under their feathers.

5. A group of flamingos is called a "flamboyance." When hundreds or thousands of these pink birds gather together, their group gets one of the coolest names in the animal kingdom: a flamboyance!

6. They live in super salty, stinky water. Flamingos love nesting in lakes so salty and alkaline that the water would burn human skin! Their tough leg skin protects them, keeping dangerous predators from bothering their nests.

7. They can sleep while standing on one leg. Flamingos can tuck their head under their wing and doze off while balancing on one skinny leg in icy cold water without losing their balance or getting too cold.
