There are almost 100 species in this family of birds. Swifts are found all over the world. These birds have the same short legs and tiny feet as their relatives, the hummingbirds. However, swifts are larger and have much longer pointed wings. This wing shape is an adaptation for spending time in the air pursuing their insect food. They look a lot like swallows ( Family Hirundinidae ) but are not related to them.
