ABSTRACT Wetland ecosystems are facing alarming rates of destruction and degradation, posing significant challenges for avian populations reliant on these habitats. Bird health is closely linked to the composition their intestinal microbiota, which primarily influenced by local conditions, through diet. Building our previous work identifying dietary variations among bird in marshes within a Ramsar site along Somme Avre rivers (France), this pilot study aimed assess relevance using fecal samples collected from ground characterize microbiota via 16S rRNA metabarcoding. We hypothesized that noninvasive sampling method would capture how traits environmental factors shape composition. Sampling was conducted during breeding season at seven locations (six one its outskirts) spanning rural or peri‐urban environments. A total 52 nine species families, predominantly waterbirds, were analyzed bacterial At phylum level, Firmicutes Proteobacteria predominant, with relative abundance genera such as Clostridium , Rothia Bacillus Caldilinea Pseudomonas varying species. The potential enteropathogen Campylobacter detected sites. Multivariate analyses revealed associated trophic guild, ecology, body length, pond surface habitat location. Additionally, weak correlation observed between host phylogeny Although limited sample size, particularly some species, constrains robustness findings, trends align ecological expectations. This highlights opportunistically low‐impact tool exploring relationship gut habitat.
