Did you spot a swallow's nest? Register it on our website!


With the end of the breeding season, the 2024 nest registration campaign also comes to a close. Register all the swallow and swift nests you know and help us protect these birds. Knowing and preserving the places where they nest is crucial for their conservation.


You can find the link to the registration form on our website!



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!



Did you know that, unlike swallows, swift chicks can endure long periods without food?


During the nesting season, swifts can spend the entire day flying, only returning to the nests to feed their chicks and rest overnight. These birds have very large feeding areas and can search for food more than 60 km away from their nesting sites.


On cold and rainy days, they may be trapped in these feeding areas, preventing them from feeding the chicks. In the nest, the chicks can lower their body temperature and become torpid until the weather improves and the adults return to the nesting sites with food.


In other birds, like swallows, due to their high metabolic rates, the parents must feed the chicks several times a day. In cases of food deprivation, unlike swifts, swallow chicks would eventually die.
