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.
