There have been at least three types of swifts seen in Cuba. The Antillean Palm-Swift is the most common among them and is seen throughout the island. The Chimney Swift and Black Swift are migrants who nest in the central to northern parts of North America.
The swifts are the fastest flying passerines in Cuba and sometimes they are all but impossible to fix a sight on one because of their speed. Their bodies are built in the same manner as a torpedo, which helps them slice through the air with the least resistance. The swifts are recognized by their silhouette which shows scimitar-shaped wings and narrow tail feathers.
