Flamingo Complexity

The complexity of living things gives evidence of design rather than accidental chance. Flamingos that live in southern Florida, the Galapagos Islands, and throughout the Caribbean provide an example of that complexity. You have probably seen photographs of these five-foot-tall pink birds wading in shallow waters and using their long necks to find food. The pink color comes from pigments in their foods, such as brine shrimp and algae. The color is absorbed by body fat and deposited in the flamingo’s feathers. Flamingo complexity involves more than color.

Flamingos move their heads through the water because their tongues pump water into their bills, where comblike structures strain out their food. This activity helps purify the water and provides nutrition for the flamingos. Their legs are an engineering marvel. What looks like a backward knee is actually an ankle joint that can be locked. You would think that a bird with no talons and no sharp beak would be easy prey for various animals that live in coastal areas. The reality is that flamingos can rest and even sleep with their ankle locked while standing on one leg in the water far from shore, out of the reach of predators.

Flamingo complexity also involves their efficient reproductive system, with monogamous pairs producing one egg a year. They build a mound away from the shore and take turns incubating the egg by sitting on the nest mound. During incubation, the flamingo will frequently stand, stretch its wings, preen itself, and carefully lift and turn the egg with its bill. The incubation period is between 27 and 31 days.

The more we learn about the unique design of various birds, the more we have to doubt that this is the product of blind opportunistic chance. In Job 39:13-30, God challenges Job to explain the unique characteristics of birds, including the ostrich, stork, hawk, and eagle. If flamingos lived in Job’s area, they surely would be included as an example of God’s wisdom and design.

Flamingos Sleep Standing on One Leg

Most of us have seen flamingos or at least pictures of them. Their bright pink plumage is hard to miss, and it is quite a sight when they travel in groups. We also may have marveled at a bird that eats with its head upside down. Even more remarkable is the fact that flamingos sleep standing on one leg. Because they retract the other leg into their body, people assumed that the one-legged stance was to conserve body heat. However, researchers investigating this odd behavior have found that it is both an energy-saving and safety design.

A flamingo’s knee is located close to its body. The joint you may have thought was the knees is actually the ankle. Researchers found that flamingos can lock their knee and stabilize their center of gravity over one leg. When flamingos sleep standing on one leg, they are very stable. When asleep, their swaying decreases sevenfold compared to when they are awake. They have virtually no muscle movements in their legs and feet while they sleep. In fact, dead flamingos are capable of standing on one leg when placed in a vertical position.

Roosting is one of the most dangerous times for any bird because predators can sneak up on them. However, Flamingos can roost while standing in water away from the shore, significantly reducing their risk of being eaten. The design of their legs and knees allows this unusual method of survival.

God has provided special equipment for survival to all living things. We cannot see the unique characteristics of flamingos as accidental mutations. God’s design is incredible and allows the great diversity we see in life on Earth.

Why Birds Stand on One Leg

Have you ever asked why birds stand on one leg? We live on a river that has a massive number of ducks in it. When the ducks are resting on the edge of the river, they generally stand on one leg. When guests visit us, they want to know why. Ducks are not the only birds that stand and even sleep on one leg. Geese and Flamingos do the same thing.

The answer to why birds stand on one leg seems to be a simple matter of the application of basic physics. For an object to be stable, its center of gravity has to be directly above the point of support. In my basic physics classes, we have some demonstrations of that principle. A spinning bicycle wheel will do strange things if its pivot point is not under the center of gravity. A top that is not symmetrical will invert when spun with its round side in touch with the table. There are toys that appear to be suspended in space, but in reality, their center of gravity is located at one end which makes it look odd when it is on the edge of a table.

When you stand on two legs, your center of gravity is somewhere between the legs. That may sound stable, but in reality, it isn’t. When you stand, you waver as your body senses that any movement you make throws you off balance. There is a constant muscular effort that counteracts this movement. Just standing for a long time can be fatiguing because a lot of energy is expended to counteract this wavering.

Recent studies with flamingos show that when they stand on one leg, the center of gravity falls directly over the point that touches the ground. Standing on one leg, the bird’s body is quiescent. When the bird is on two legs, there is more muscle movement and the center of pressure on the foot touching the ground changes. If you look carefully at a duck standing on one leg, you will see that it stands a little lopsided, so the mass is completely above the point of support. In addition to energy conservation, standing on one leg allows birds to withstand cold temperatures by keeping one leg close to the body. So thermoregulation is also involved in this odd-looking design.

So if you have ever asked why birds stand on one leg, remember this. Anytime we see something in nature that we don’t understand; it is almost 100% sure that there is a design feature involved. What the animal is doing may look strange, but it has at least one significant function. Truly we can “Know there is a God through the things He has made” (Romans 1:18-20).
