Table 6 Statistical comparison of results of this study with previous intensive studies of redstart-cuckoos

Parameter (%)	Rutila et al. (2002) [16]		Thomson et al. (2016) [24]
	χ ² (df = 1)	p	χ ² (df = 1)	p
Overall parasitism rate	16.32	<0.001	0.20	0.66
Effectively parasitised nests	0.30	0.58	0.001	0.98
Cuckoo egg in the nest cup	8.48	0.004	0.26	0.61
Cuckoo egg on the nest rim	12.34	<0.001	0.03	0.86
Cuckoo egg dumped on incomplete nest	0.87	0.35	0.79	0.38
Cuckoo egg on the ground outside	0.20	0.65	0.08	0.77
Mimetic egg rejection	–	0.19	–	0.14
Non-mimetic egg rejection	–	0.73	–	0.001

Data for parasitism rate and egg positions were analysed with Pearson’s chi-square test, host rejection rates (mimetic egg = blue model, non-mimetic egg = spotted model) were analysed with Fisher’s Exact Test (all df = 1). Desertion was not a specific response to foreign eggs (Results) and was therefore excluded
