Swifts' Colonies



With the peak of summer comes the peak of swift activity and the ideal time to locate and register their colonies!


In your town or village, you’ll likely see flocks of swifts, "screaming" loudly, weaving between buildings at incredible speeds. The big challenge is discovering where they nest!


Under the tiles of a house or monument? In the shutter boxes of a residential building? In the cladding of an industrial building? Help us find out!


The best time to detect a swift colony is at dawn and dusk. In July, as most chicks are already grown and always hungry, the adults visit the nests more frequently, making them easier to locate!


If you find one of these colonies, register it on the website!
