英文摘要	To perform their long-distance postnuptial migration, trans-Saharan migratory passerines must refuel repeatedly at different stopover sites. But some stopover sites have a specific role because most of the reserves needed to cross large ecological barriers (e.g., sea or desert) are stored there. This is the case in the west of the Iberian Peninsula, which is the main fattening area for European pied flycatcher Ficedula hypoleuca before they cross the Sahara. Upstream, no sites have been sampled in Western Europe between Great Britain and the southern Iberian Peninsula. Southwestern France is a main postnuptial route for this species with funnel effect between the end of the Pyrenees barrier and the Atlantic Ocean. In this area, we estimated energetic parameters from capture-mark-recapture data obtained during standardized monitoring. The mean stopover duration was relatively high, estimated at 8.4 days after the first capture by a capture-mark-recapture model and at 16.8 days assuming a similar duration before the first capture. Individual minimum stopover durations of 23 and 28 days were recorded. Pied flycatchers were fattening at an average rate of 0.29 g day(-1) (3.1% of lean body mass) consistent throughout the season and independent of initial body mass, supporting the idea that the area was targeted for fattening. Very high fuel deposition rates over short durations were observed in several individuals (from 5 to 13.3% of their lean body mass). The mean fuel load did not differ by age or year and averaged 33.8% of lean body mass. The mean fuel load of the 25% heaviest fraction of birds was 57.3%, providing a flight range covering 80% of the distance to the southern margin of the Sahara. Hence, the departure fuel load was insufficient to cross the Sahara. At least one additional stopover would be necessary in the Iberian Peninsula, but for a moderate extra fuel. Individuals fattening under time pressure coexisted with individuals in prolonged stopover. Both behaviors are on few specific sites. Although the Sahara is still far away, South-West France is not solely a transit region concentrating birds because of the Pyrenees barrier. It must be an area of high refueling.
