Storks do not have a syrinx (an organ that allows them to make sounds and imitate others), so their way of communicating is by tapping their beaks together while bending their necks back to amplify the sound.

In 1972, only ten pairs of white storks nested in Catalonia. Reintroduction and protection projects have significantly increased their population.

Throughout their lives they tend to mate for life, and each year they usually use the same nest to breed. There is no sexual dimorphism between genders.
