Fig. 5. Corrected evening weight versus time in 88 2y+ Yellow Wagtails from Löddesnäs and Foteviken, 13.8 - 13.9 (several years). Weights corrected to adult mean wing-length 83.6 ± 0.2 mm.
Fig. 6. Corrected evening weight versus time in 74 2nd brood southern flava from Foteviken, 13.8 - 14.9 (several years). Weights corrected to 1y mean wing-length 80.4 ± 0.3 mm.
Fig. 7. Evening weight versus wing in 56 Yellow Wagtails from Ljunghusen, 28.8 - 10.9.2002, the same birds that were fat-ranked (see Table III).
Fig. 8. Distance flown versus time in Norwegian and Swedish Yellow Wagtails migrating by way of S. Scania to Africa. The diagram is based on a selection of direct recoveries (n=71); mean progress 74 km/day. Dashed line in Europe indicates average performance 100 km/day; the three fastest movements (all exceeding 100 km/day) concern Brescia, Capbreton and Nouakchott.
