Untrained birds’ ability to recognise predators with changed body size and colouration in a field experiment

Table 2 The results of parametric pairwise post hoc comparisons (Tukey HSD post hoc tests) of the proportion of visits to feeders with particular dummies in the first experiment

Dummy	LH	SH	LPH	SPH	P
LH	–	− 10.877	− 14.887	− 5.230	− 7.251
SH	0.003	–	–	− 1.727	13.286
LPH	< 0.001	–	–	− 6.968	− 2.011
SPH	0.029	0.199	0.013	–	4.666
P	0.012	0.001	0.167	0.040	–

The right-top part of the table refers to t-values, the left-bottom part to p-values. Positivity of t-values indicates that the mean value of the number of visits to a feeder with the dummy in a column is higher than the mean value related to the dummy in the row. LH = unmodified sparrowhawk (‘large hawk’); P = unmodified domestic pigeon (‘pigeon’); SH = downsized sparrowhawk with unmodified colouration (‘small hawk’); LPH = life-sized sparrowhawk with pigeon colouration (‘large pigeon-hawk’); SPH = downsized sparrowhawk with pigeon colouration (‘small pigeon-hawk’)
