Common Swift (Apus apus)
It is always a delight to watch and listen to the Common Swifts (Apus apus) flying over Lac Léman. But their speed and their incredible agility in flight make it difficult to photograph them. Common Swifts (Apus apus) are fascinating birds. Except when nesting, they spend their whole life in the air. They feed, drink, mate and even sleep in flight!
