...Evidence for the equilibrium hypothesis is indirect and based on studies documenting the existence of costs associated to hosts’ antiparasitic defenses (Rohwer et al., 1989; Lotem et al., 1992; Antonov et al., 2009; Krüger, 2011)....

...Egg-pecking or egg-touching behavior is considered reliable proxies for egg recognition (Soler et al. 2002, 2012; Underwood and Sealy 2006; Antonov et al. 2008, 2009), even when acceptance decisions occurs (Ruiz-Raya et al. 2015; Soler et al. 2017)....

...Avian obligate brood parasites generally impose high fitness costs on their hosts, resulting in sophisticated coevolutionary arms races (Davies & Brooke 1989; Moksnes et al. 1990)....

...However, despite the apparent benefits of rejection, there is substantial variation both among and within host species used by cuckoos in their responses to foreign eggs (Davies & Brooke 1989; Moksnes et al. 1990; Martı́n-Gálvez et al. 2007; Stokke et al. 2008)....

...Despite some indirect demonstrations of conditional host responses (Davies & Brooke 1989; Moksnes et al. 1993), there is very little direct evidence for acceptance of cuckoo eggs once host individuals have discriminated against them (Lindholm 2000; Soler et al. 2000)....

...The most ubiquitous host antiparasite defence is egg discrimination and rejection, to which some parasites have responded by evolving mimetic eggs (Rothstein & Robinson 1998)....

...However, even among cuckoo hosts, a higher level of phenotypic plasticity in rejection decisions is expected if ejection is costly and the risk of parasitism varies considerably (Rothstein & Robinson 1998; Lindholm 2000)....

...Possible explanations invoke a lack of necessary genetic variation underpinning egg discrimination, or discrimination developing with age/experience or having only evolved in some host populations sympatric with the brood parasite (Rothstein & Robinson 1998; Stokke et al. 2005; Røskaft et al. 2006)....

...…shells of parasitic eggs (Spaw & Rohwer 1987; Picman & Pribil 1997) may render rejection especially costly for smallbilled hosts that have to puncture the parasitic egg in order to remove it (puncture ejection) or desert the clutch (Moksnes et al. 1991; Røskaft et al. 1993; Antonov et al. 2006)....
