The Common Swift is an insectivore of the Apodiformes bird order which pays visit to our towns and cities over the spring/summer period.
While here they breed, depositing an average of two eggs in small crevices on building facades and under our roofs in what is the only time of the year they touch dry land.
The rest of the year they spend flying, eating, sleeping and copulating in the air.
They are designed to fly at great speeds and to capture insects, with long, narrow wings, fusiform bodies, large mouths to capture their prey and short little legs for gripping onto walls when making their nests.
Catalan common name: Falzia.
Spanish common name: Vencejo.
