The swallows, which belong to the family Hirundinidae, have an elegant silhouette with their neck scarcely marked and their rounded head. Their very long and pointed wings, their well-developed tail gives them in flight an aerodynamic profile very useful for their seasonal migrations. Twice a year, in fact, they travel an incredible journey of seven to ten thousand kilometers, with only fuel the reserve of fat they have built before leaving.
