Résumé :	Capsule: We found high diet overlap and different uses of space and time between Moustached Warblers Acrocephalus melanopogon and Reed Warblers Acrocephalus scirpaceus breeding in sympatry at a marshland in Spain.Aims: To study the degree of diet overlap between both species, their space use on a local scale and their breeding phenologies.Methods: We studied the breeding phenologies of the two species by standardized ringing activity. Spatial distribution was investigated by point counts. We determined diet composition from emetic samples and we collected invertebrates by standardized sweep-netting to estimate food availability.Results: Diet and prey selection were similar among species. Conversely, spatial overlap was relatively small (
