The long legs of the bird fit easily beneath its tail and its wings, and its whole body is covered with feathers so that air might penetrate them and aid it to fly. Since the food of birds consists of seeds and the flesh of animals that they consume without chewing, they have no need of teeth. Instead, God created for birds a hard and sharp beak that cannot break when tearing off meat or suffer injury when gathering seeds.

To enable this creature to digest the food it has not chewed, it has been given a powerful digestive system and a warm body.

Furthermore, birds reproduce by laying eggs so they can remain light enough to fly; if their offspring were to grow in their stomachs, they would become too heavy to fly." Then the Imam referred to a general law, saying, "Thus all the peculiarities of a bird's creation conform to its environment and its manner of life."[^1] The question of animal speech—the means by which animals communicate with each other—is another divine sign.

They possess a special kind of language that enables them to communicate with each other. The Noble Qur’an thus relates the story of an ant addressing the Prophet Solomon, peace be upon our Prophet and him, "An ant said, "O ants, enter your dwellings lest Solomon and his army unwittingly trample you underfoot." (27:18) Modern scientists have discovered a sophisticated system of communication among the animals that is more complex and precise than our own system of communication.

Crissy Morrison writes, "If we put a female moth next to the window of our room, it emits soft signals that a male moth picks up from an incredible distance and it sends its own signals in return. However much you may wish to disturb this communication, you will be unable to do so. Does this weak creature carry some kind of transmitter, or does the male moth have a receiver concealed in his antennae?

"A cricket rubs its legs together, and the sound can be heard up to a kilometer away on a quiet, still night. In order to summon its mate, the male cricket sets sixty tons of air in motion and the female cricket sends a warm response to his wooing by some physical means, although apparently no sound is audible from her. "Before the invention of radio, scientists used to imagine that animals communicated with each there by means of smell.

Supposing this hypothesis to be true, it would still be something of a miracle, because the smell would have to move through the air to reach the nostrils of the female insect.
