    Counts were carried out using the IPA method described in Blondel et al (1970), IBCC (1977) and Blondel et al (1981). According to the protocol, two passes with a twenty-minute data collection per listening point were carried out each year (end of April and beginning of May for early breeders and end of May and beginning of June for late breeders), in the morning, in good weather and no wind. A value of 1 is assigned to a species for any visual or auditory contact with a pair, an occupied nest, a family, an adult carrying food, or a singing male, and a value of 0.5 is assigned to a single non-singing bird. The values per species and per passage are added up to a maximum index of 5. For each listening point, the best index of the two passages was retained for the analysis. Data collection was carried out between 6.30 and 9.00 a.m. during the first pass and between 6.00 and 9.00 a.m. during the second. For more details see Michelat et al. (2023).
