Through the monitoring of common breeding birds (MHB), we keep an eye on population development and any changes in the range of common breeding bird species. The populations of breeding birds have been surveyed annually since 1999 on 267 representative kilometre squares distributed throughout Switzerland. This allows population trends of more than 70 common and widespread bird species to be identified.

The MHB network is dense. Here we are standing at the upper edge of one square, the next is on the southern slope at the centre of the picture.
Among other things, the MHB is used to monitor the populations of numerous forest dwellers such as the Common Firecrest.
