🌞🦩 In warm climates, flamingos keep cool by standing in water. The cool water temperature cools the blood coming up to the bird’s body from its legs and feet.

❄️🦩 Bird House keepers apply this natural thermoregulation to keep our flock warm in the winter, too! The flamingo pool is heated to 70 degrees Fahrenheit to keep the birds comfortable—even when it’s snowing!

🌨🦩When the forecast calls for ice and freezing rain, however, the flock stays indoors. If ice crystals stay on the birds’ bodies, they may not be able to maintain their optimal temperature.
