Did you know that Cozumel Island, shares a part of it’s heritage with San Juan Capistrano. The island’s name, in Mayan, is “Cuzaam luumil,” or “island of the swallows.” Although they are known more for white sandy beaches and clear blue waters, they are home to many swallows. The swallows live among the mangrove and in aquatic caves known as cenotes.
According to Wikipedia
The swallows, martins and saw-wings, or Hirundinidae, are a family of passerine birds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term Swallow is used colloquially in Europe as a synonym for the barn swallow. There are around 90 species of Hirundinidae, divided into 19 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are non-migratory.
