The number of landings of particular bird species to all tested dummies in the first experiment divided by the number of landings during the preceding empty controls. Values below one indicate dummy’s negative effect on the landing rate. Parus—great tit (Parus major), Cyanistes—blue tit (Cyanistes caeruleus), Poecile—marsh (Poecile palustris) and willow tit (Poecile montanus) together, Chloris—green finch (Chloris chloris), Passer—domestic (Passer domesticus) and tree sparrow (Passer montanus) together. Titmice taking only a single seed item are in blue, while specialized granivores collecting multiple seeds and thus staying longer at the feeder are in green
