Résumé :	Various behavioural aspects of the Wallcreeper were studied in the mountains of central Slovakia during 1982-2001. Foraging habits were recorded during 170 dawn-to-dusk observation days and 458 "partial" observation days. Wallcreepers foraged mainly on rock faces (85% of the time spent foraging). Birds took prey from small cracks in the rock itself and also from grassy and mossy patches. Wallcreepers sometimes flushed small insects from the rock or grassy patches by wing-flicking and caught them in the air (5%). Wallcreepers caught prey also by flycatching (7%). Some insects, spiders or molluscs were picked off rock-walls while the birds were hovering (3%). While climbing rock faces, birds used wing-flicking to disturb prey hiding in rock crevices or in grassy and mossy patches. Several modes of flight were distinguished while Wallcreepers were looking for the prey on the rock face or chasing the prey in the air.
