Fig. 4

The number of landings of all tested birds to particular dummy pairs in the second experiment divided by the number of landings during the preceding empty controls. Values below one indicate dummy’s negative effect on the landing rate. Asterisk indicates a significant difference; dot indicates a merely indicative level of significance (post hoc Tukey HSD t-test). LH = unmodified sparrowhawk (‘large hawk’), P = unmodified domestic pigeon (‘pigeon’), LTH = life-sized sparrowhawk with great tit colouration (‘large tit-hawk’), LRH = life-sized sparrowhawk with robin colouration (‘large robin-hawk’)
