Résumé :	Migratory birds travel long distances and use diverse habitats, potentially exposing them to a broad range of microbes that could negatively affect their health and survival. Gut microbiota composition may be related to organismal health especially during periods of impaired immunity due to stress, by functioning as a reservoir for potential pathogens. We provide an insight into the composition of the gastrointestinal microbiota in migratory Red Knot (Calidris canutus) and Ruddy Turnstone (Arenaria interpres) staging in Delaware Bay, USA, by analyzing fecal bacterial communities of three individuals per species with 16S rRNA clone libraries. In the 313 bacterial sequences we analysed from Red Knots, we identified 19 bacterial classes across 29 genera, and from the 218 Ruddy Turnstone sequences, we identified 11 bacterial classes across 17 genera. In Red Knots and Ruddy Turnstones,
