The Wonder of Birds

The Wonder of Birds - Bald Eagle

We live on the edge of the St. Joseph River in Michigan. By the river and surrounded by woods, I have the joy of observing the wonder of birds in enormous varieties. As I watch geese, swans and ducks take off and land on the river, I am amazed at the way they put their feet out and water ski to a stop. I enjoy seeing them stand on one foot, seemingly asleep with half of their bodies ready to react to any danger.

When our resident bald eagle flies by 100 feet above the water, the ducks turn their heads to track the eagle. The eagle swoops down and picks up a small dead fish which I couldn’t see from 20 feet away. I watch three species of woodpeckers hammer away at the trees on the edge of the river with such force that bark flies in all directions. Still, the design of their skulls lets them do this for hours on end without brain damage.

I watch the finches and nuthatches pick off berries from the poison ivy and eat them in the dead of winter. They never have any problem with the oil that I am allergic to. I watch the hummingbirds come to my feeders and hover for a long time, eating the sugar solution and engaging in territorial combat. I hear the birds singing as they mark their territories, with each species having its own peculiar melody.

As a person trained in physics and chemistry, I am enthralled by the wonder of birds and their widely varied properties. The Cornell Lab of Ornithology has an ongoing study of the properties and abilities of birds. One area of research is the specialized equipment individual bird species have. The eagle’s eyes are incredible optical tools that give it the ability to see a small fish from 100 feet above the water.

Woodpecker heads show engineering with their shock-absorbing design to prevent brain damage from the constant hammering they use to get bugs. People researching flight techniques study the wing design of hummingbirds which allows them to hover. The design of the bird’s gut prevents the poison ivy oil from lingering long enough to cause a reaction.

All birds have design features that allow them to survive. Their digestive and waste removal systems avoid the use of a bladder. The vascular system with a unique heart design allows the Swainson’s thrush to travel 3000 miles in a single flight with its heart beating 840 times a minute. Darwin showed us that the design of the bird genetics is flexible enough to allow their beaks to vary depending on what diet is available in their environment.

Humans throughout history have depended on birds as a food source. Where would we be in America without chickens and turkeys? God sustained the ancient Israelites with quails, a provision that continues today in that part of the world. In some areas, songbirds are a source of meat even though they are small. For those of us who look for evidence of God’s design in the natural world, birds are an incredible example of how much has to be done to produce an animal that can do what birds do.

The wonder of birds is not reasonably explained by accidental change. We all need to be concerned about the fact that between human exploitation, the removal of resources and habitat by humans, natural climate change, and pollution, the population of birds on our planet is getting smaller and smaller. Since 1970, three billion birds have vanished from the United States. God told us to take care of the world in which He has placed us. Caring for all of God’s creatures, including birds, is everyone’s responsibility.

Hidden Design in a Bird’s Eye

Hidden Design in a Bird’s Eye

Most people know that birds have excellent vision. Eagles can spot a mouse from high overhead. How can they have such sharp vision? Science has revealed the hidden design in a bird’s eye.

The secret of a bird’s eyes was detected first, not in an eagle, but in the eye of a chicken. Color cones are cells in the retina located in the back of the eye. The cones capture the image that the lens focuses on the retina. Human eyes have cones of three different colors: red, blue, and green. Examining the retinas of chickens’ eyes, scientists found that they have five different colors of cones. But it isn’t the number of different color cones that is the most amazing feature.

Much more interesting is the arrangement of the cones. The cones for each color are different sizes. Imagine taking many circles in five different sizes and colors and arranging them on a surface, trying to fit the maximum number of circles into the area. If they were all the same size, you might put them into a grid, but since the circles are in five different sizes, packing the maximum number into the area becomes much more difficult. In packing cone cells onto a retina, more cones will give a higher resolution (sharper) image.

The arrangement of cones in the chicken retina seemed to be haphazard until scientists studied them more closely. What they found was something they call “hyperuniformity.” It’s a mathematically elegant concept that appears to be disordered but is actually optimized with a hidden order. You might call it “disordered hyperuniformity.” It’s the hidden design in a bird’s eye.

What appears disordered is the best possible arrangement to evenly distribute the maximum number of unevenly-sized cones over the retinal surface. Scientists are applying this to many other areas. Hyperuniformity could improve cameras and scanning equipment. It could also improve such diverse processes as mixing concrete, making glass, or any application where you need to distribute solid particles evenly.

How did the cells in the chicken’s eyes get arranged so perfectly? Was the hidden design in a bird’s eye an accident, or is this another example of the work of an intelligent Designer?

Blessing of Turkeys

Blessing of Turkeys

Turkeys are native to North America and live in the wild in every state except Alaska. They got the name “turkey” when Turkish merchants brought them into Europe. Since they were very abundant and easy to kill, indigenous North Americans domesticated them by around 800 BC. Many native American tribes considered turkeys to be a gift from deity. Ben Franklin thought that the turkey instead of the bald eagle should be the national bird of the United States. The blessing of turkeys is that they seem to be designed uniquely to meet the needs of humans.

Biologically, turkeys are of the order called Galliformes, which are ground-feeding birds that include chickens, grouse, guinea fowl, quail, and pheasants. Turkeys have large breasts, are poor fliers, and can adapt to almost any environment. They are omnivores that will eat just about anything they find on the ground.

From an evolutionary standpoint, it is hard to imagine how turkeys have survived. The only defensive weapon they have is the spurs on the feet of the males. Those of us living in areas where there are large numbers of wild turkeys have learned to be careful when around them. A turkey will attack anything it sees as subordinate. Recently in the spring mating season, a turkey flew through the open window of a pickup truck and attacked the driver, who required more than a dozen stitches. But a turkey is no match for a wolf, bear, or eagle.

When God blessed Noah and his family in Genesis chapter nine, He told them that all living things were delivered into their hands. He said that “every moving thing that lives shall be meat for you; even as the green herb have I given you all things.” The ease of domesticating chickens and turkeys comes from the planning and wisdom of God. The blessing of turkeys for Thanksgiving dinner is a special reminder of God’s creative wisdom. It also reminds us that we are responsible to care for the wonderful blessings of food God has provided.

Why Roosters Don’t Go Deaf

Why Roosters Don't Go Deaf
Roosters are loud! They can hit volumes as high as 140 decibels which is the level of sound on an aircraft carrier deck. For humans, a noise above 120 decibels, about the level of a chainsaw, can cause permanent hearing damage. So you may wonder why roosters don’t go deaf.

Belgian researchers writing in the journal Zoology have the answer. They examined the skull structure of the birds. The researchers found that they have a built-in defense against loud sounds in the form of a sound barrier. When a rooster adjusts its head and neck to crow, small flaps of tissue close the ear canal. They effectively act as earplugs to dampens the noise significantly.

On top of that, the study reveals that roosters can regenerate the tiny hair cells deep within the ear that can become damaged by loud noises. Humans can’t do that, which is why deafness caused by loud sounds is permanent for us. For roosters, a degree of deafness would likely only be temporary if it happened at all.

“Micro-CT scans of a rooster and chicken head show that in roosters the auditory canal closes when the beak is opened,” the researchers wrote. “In hens the diameter of the auditory canal only narrows but does not close completely. A morphological difference between the sexes in shape of a bursa-like slit which occurs in the outer ear canal causes the outer ear canal to close in roosters but not in hens.”

So now you know why roosters don’t go deaf. God’s design in every living thing on Earth shows wisdom and an exceptional understanding of the problems that each species faces. The more we learn about the creation, the more we understand the wisdom and creative nature of God. “We can know there is a God through the things He has made” (Romans 1:19-20).
