Switzerland's largest tunnel for learning to fly

 

69 tunnels were built, including 5 flight tunnels. Part of them houses resident birds (not releasable) and another part, prohibited to the public, is dedicated to raptors and other birds that the CRR wishes to release.

The Raptor Rehabilitation Center has the largest tunnel aviaries in Switzerland. Their lengths ranging from 36 to 50 meters make it possible to observe the flight capacity of birds, before releasing them.

The CRR also has an aviary reserved exclusively for passerines as well as 4 multipurpose aviaries to accommodate other birds and / or mammals.

More than ten boxes, over a square meter in size, are installed to receive hedgehogs.
