A member of the swift family, which usually migrate depending on the season. The Gallian swift, however, stay on the continent all year round. It is thought they once migrated, but it is not known why they now stay in one place. As they once traveled long distances, they are strong fliers capable of sustained flight at high speed. They also have the ability to remember a location and return there reliably. They nest in cliff walls, and these nests are considered a delicacy in eastern lands.
