Food intake and body mass increase from day 1 in migratory dunnocks in two 12-day magnetic displacement experiments during autumn In the first experiment birds were displaced to the southern destination area (Control n=11; South n=12) from day 1 (Oct 5). In the second experiment birds were displaced both to the southern destination area and the northern limit of species distribution range (Control n=6; South n=8; North n=7). Moreover, the magnetic field was changed every day during 6-day period (until the dashed line) and then kept to a constant value. The geographical positions corresponding to the simulated magnetic displacements were Sweden (Control), southern France (South) and northwestern Russia (North) as reported in Fig. 2 and Table 2. Data represented as mean±s.e.m.
