Bird Migration System

Yesterday we looked at bird migration, particularly why birds migrate, and noted several reasons. The facts indicate a bird migration system that defies a chance explanation.

According to the All About Birds website, “On a single autumn night with favorable winds, there can be more than one billion birds in the air over the United States alone.” That is more birds than people in the U.S. There are more than 300 species of birds in North America that migrate long distances, which has a major effect on life on this planet.

To prepare for a long-distance flight, a bird must bulk up. The bird must be in top physical condition for flying, with energy stored for a grueling flight with infrequent or no stops. The timing also must be right. That means the bird must assess the weather and know when it’s right. Many other factors are involved in the bird migration system.

An interesting fact about bird migration is that they can travel thousands of miles, often along the same route, and arrive in the same place year after year. Even young birds migrate on their own just a couple of months after they hatch. So how can they find their winter home even though they’ve never been there before? Birds use many navigation methods, including the magnetic field, the sun, the moon, and stars. They also use familiar landmarks like ridges, rivers, and other features. They even use their sense of smell. With all that in mind, they must avoid predators and handle storms, strong winds, and sometimes human-made threats such as artificial light, communication towers, wind turbines, and tall buildings.

To learn more about what’s happening in bird migration today, check out the BirdCast website. There, you can see how many birds are moving across the lower forty-eight United States. The more we examine it, the more we see that the bird migration system defies a chance explanation. It’s another evidence of God’s design.
