Many species of fish, mammals and even insects make astonishing migrations.
But of all the living things on Earth, the most mobile of all are birds.
During their journeys, birds make use of countless features and attributes, every one of which is a separate convincing proof of creation.
The Gaussmeter (which measures force, frequency and magnetic fields), the Earth’s magnetic field, aerofoil shape, wing tip vortex . . . To most people, these terms may not mean anything.. They can be unaware of such details as that-for example-the Earth’s innermost core is of solid iron, while the outer core is liquid; and that the movement of this outer layer around the inner sets up a magnetic field. Nor do many realize how we benefit from that magnetic field for our very survival on this planet.
Apart from engineers or professionals having a special interest in the subject, people may not know that the airfoil shape present in fans, airplane propellers and the wings of birds establishes a lift force when air flows over it, and that this is vital at both take-off and landing. Engineers and experts make use of this information when designing new planes. They also take into account the effects of the magnetic field and take precautions against possible dangers.
However, it’s not only those people with specialized training in this field who make use of such facts. Birds, endowed with countless miraculous abilities by Almighty God, exhibit miraculous behavior throughout their lives. Even though they have received no training in this area of aerodynamics, yet they too display abundant proofs of the perfection of His creative knowledge.
Birds’ Expert Estimation of Altitude and Air Conditions
Migratory animals must estimate air conditions correctly-and in advance. This is something requiring meteorological expertise. The Australian bogong moths are one example of this. These moths fly hundreds of kilometers towards a cool region in the Australian Alps in order to escape the humid climate where they spend their caterpillar stage.
During spring, their caterpillars feed in green meadows. When temperatures begin rising in summer, they enter their pupal phase and later emerge as small grayish-black moths. Then, rather than endure the summer heat, they set out to a long journey for the Australian Alps, where millions of these long-distance travelers spend the summer, gathering in rock crevices and caves,
In order to reach the Alpine peaks, these small insects must take advantage of the seasonal cold front that moves in a south-easterly direction and that will carry them to where they will rest over the torrid summer months. Scientists believe that these creatures are able to detect barometric pressure changes, or changes in the ion balance in the air, that allow them to make perfect estimates.
The Miraculous Systems in Birds’ Ears
Birds have a barometric sense in their ears similar to that in moths. So sensitive are they to even the slightest change in altitude that even if heavy clouds prevent them from seeing the ground, they are able to continue
A bird’s air-pressure sense helps it to estimate
Why Do Birds Generally Migrate at Night?
Most birds carry out their vital functions-feeding, nest-building-in the daytime. But for long journeys they prefer night. Coastal birds, as well as such small birds as flycatchers, golden orioles, white-throated warblers fieldfares, and most species of sparrow are classic nocturnal migrants. There is enormous activity in the night sky. Telescopic observations during the full moon indicate that up to 9,000 birds an hour pass along the migratory routes. These nocturnal migrations begin one hour after sunset, reach their peak just before midnight, and slowly decline until the day dawns.
Nocturnal migration provides birds with a number of advantages. The most important of these is that it enables them to avoid predators. The majority of nocturnal migrants are small-sized and have weak
During Nocturnal Migration, There is No Danger from High Temperatures
Another likely-though not fully proven-advantage to nocturnal migration is the low ambient temperature. For birds that constantly flap their wings all day, solar rays pose a risk of overheating. Nocturnal migration prevents that danger. In addition, the energy they expend in
In all likelihood, birds determine the distances they are able to
For all these reasons, birds prefer to migrate at night, and their bodily structures have been created in line with this. Of course, there are also birds that God has created to
In conclusion, birds migrate in the manner that their body structures and life styles permit. God created these creatures and equipped them with particular abilities. Everything they do is another proof of the existence and might of God. Therefore, their every action is equivalent to praise of God.
Some migratory birds
We do not yet fully understand how birds determine altitude. However, high-altitude
Birds Are Immune to the Difficulties of High-Altitude
How do migratory birds manage to withstand the cold at such high altitudes? This is still a mystery. Temperatures at these altitudes can fall to as low as -14 degrees Celsius, and migratory birds must survive in this freezing cold for days on end.
Every living thing is created in such a way as to be able to cope with the difficulties it may encounter during the course of its life. Geese can
Don’t you see that everyone in the heavens and Earth glorifies God, as do the birds with their outspread wings? Each one knows its prayer and glorification. God knows what they do. (Qur’an, 24:41)
[God is t]he Originator of the heavens and Earth. When He decides on something, He just says to it, ‘Be!’ and it is. (Qur’an, 2:117)
The Advantages of
As already stated, birds consume as much food as they can before setting out to their migrations. They convert this food into body fat, because fat is the most ideal fuel. When 1 gram of fat is metabolized, it releases twice as much energy and water as does the same weight of protein or carbohydrate. During migration, these accumulated fats are consumed. However, a number of problems accompany this spare energy that birds carry with them.
For example, the red-throated pipit carries a fat load representing 90% of its normal body weight. This species slowly burns this fat during its 24-hour migration.
Birds use a specific quantity of fuel in order to be able to carry this load of extra weight up to particular altitudes. When they attain the appropriate height, their most advantageous thing to do is to continue
Many people are even unaware of these tiny birds’ existence. But when we examine them in detail, we find ourselves looking at extraordinary miracles of creation. These creatures accomplish flawless journeys under conditions that no human being could ever survive. There is no doubt that Almighty God has created birds with all these features. These wondrous creatures are just one of the manifold manifestations on Earth of our Lord’s omniscience.
