ing the journey. Yet white storks complete their journey in three weeks by
gliding between the heat currents for 6-7 hours a day and thus saving most
of their energy.
Since the sea warms up more slowly than the land, there are no heat cur-
rents over the sea. For this reason, migratory birds prefer to migrate over
land instead of making long sea journeys. You may have seen flocks of
storks that cover the sky at certain times of the year. That is because storks,
too, prefer to migrate over land. You may not be aware of the fact that
there is no warm air over the sea, but storks know it very well.
On the other hand, albatrosses, seagulls and other sea birds save energy by
using air currents caused by high waves. These sea birds that fly over the
waves benefit from the lift force of the air that turns upwards.
As seen in the examples given here, all birds know which techniques they
will use, where they will go and which route they will take. No confusion
arises for those that fly by using warm air currents and those that fly by
using air currents caused by the waves. This is because Allah inspires every
creature with the knowledge it needs. In the Qur’an, Allah points out birds’
movements in the air and states:
