Actually, birds exhibit intelligence sometimes associated with apes and small children.
In addition, birds are remarkably sensitive.
The New York Times recently wrote that robins can find worms with their sense of hearing. The worm’s tiny bristles rustle against the sides of their burrows.
Birds are able to navigate using a magnetic sense, still not completely understood.
They have other talents which humans do not. They can use each eye independently. They can fly with one eye closed and half of their brain asleep and still navigate better than a human driver texting in traffic.
The proverbial "eagle eye" is not a myth either. Bald eagles are renowned for their excellent eyesight. They have two foveae or centers of focus, that allow the birds to see both forward and to the side at the same time. Bald eagles are capable of seeing fish in the water from several hundred feet above, while soaring, gliding or in flapping flight. This is quite an extraordinary feat, since most fish are counter-shaded, meaning they are darker on top and thus harder to see from above. Fishermen can confirm how difficult it is to see a fish just beneath the surface of the water from only a short distance away. Eagles, like all birds, have color vision. An eagle's eye is almost as large as a human's, but its sharpness is at least four times that of a person with perfect vision. The eagle can probably identify a rabbit moving almost a mile away. That means that an eagle flying at an altitude of 1000 feet over open country could spot prey over an area of almost 3 square miles from a fixed position.
When we see the birds fly by, remember that we are seeing creations of God which are far more sophisticated than any man-made drones.
