Fig. 2

Recognition of conspecific (black circles) and heterospecific model eggs (grey circles). Differences between “previous session” (before parasitism) and “egg session” (after parasitism) for nests that received either conspecific or heterospecific eggs, regarding: a first-contact touches first visit (number of touches in the first visit), b first-contact touches per visit (number of touches for all visits corrected by the number of visits) and c incubation touches (number of touches during incubation corrected by the incubation time); see Methods section for a more detailed explanation of each variable. We show nests separately (i. e. receptors of conspecific or heterospecific eggs) in the “previous session” in order to clearly illustrate differences between both sessions for the two types of nests. Values are presented as means ± SE
