Since the beginning of spring two experienced ornithologists are supporting INRAE researchers to conduct bird surveys in farms.

One of the indicators of resilience established during the first phase of the project was the presence of birds in the farms under study. The importance of birds in the agro-ecosystem lies in their ability to help reduce pest pressure by consuming certain insects and larvae. The survey protocol employed by the team focused on identifying birds within a 100-meter radius primarily based on their distinctive songs.

This operation was repeated 10 times, with surveys conducted once or twice in different locations within the farms and 8 to 9 times in the surrounding areas. Thus far, two bird species have left a significant impression on the team. The first species, Luscinia megarhynchos (Common Nightingale), was found to be present throughout the surveyed farms and possesses a distinctively strong and melodious song. The second species, Coracias garrulus (European Roller), stands out due to its stunning blue and brown plumage, adding visual allure to the avian community.

These observations highlight the role of birds in the surveyed farms, with the Common Nightingale serving as a ubiquitous indicator of a healthy ecosystem.
