During migration, migratory bird species often aggregate at the same stopover sites due to geographical features that channel routes (coasts, valleys) or locally abundant food resources (e.g. reedbeds, fruiting bushes). In migration ecology, however, behavior is studied on a single species, limiting generality of inferences and their application habitat management. If decisions are similar across co‐occurring characterizing ecology community level could provide more comprehensive insights. Using recent advances in modelling, we adapted multi‐species capture‐recapture model 1) quantify synchrony departure probabilities 2) identify covariates driving this synchrony. We applied three songbirds commonly captured French sites: sedge warbler Acrocephalus schoenobaenu s, reed scirpaeus bluethroat Luscinia svecica . Departure were largely synchronous with time since arrival (TSA) as primary synchronizing factor weather conditions secondary influence. High timing produced waves migrant departures consistent patterns suggesting shared fuelling strategies. Although phenomenon has been documented via visual counts radar, it not formally quantified species‐level using methods. Our flexible can test hypotheses regarding spatial decisions. With decades capture–recapture data available Europe North America, our approach offers new potential for studying level, over large geographic temporal scales.
