Résumé :	Migratory orientation of Dunlins Calidris alpina at sunset was studied by using orientation cages, during autumn migration in SW Iceland. The aim of the experiments was to examine whether orientation funnels can be used to record the directional behaviour of shorebirds. The results clearly demonstrate that Dunlins are capable of expressing their preferred migratory direction in funnels. Unmanipulated Dunlins showed a well-oriented mean direction towards geographical SSE which is in excellent agreement with available ringing recovery data on Dunlins linked to Iceland. This opens up the possibility to perform carefully controlled experiments to investigate the orientation and navigation mechanisms of migrating waders.
