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

From: The common redstart as a suitable model to study cuckoo-host coevolution in a unique ecological context

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
  1. 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
