Figure 2 – figure supplement 1: Differences in steroid hormone concentrations at baseline levels and the three nest stages

For each trial and bird, we provide steroid hormone values (DHT = dihydrotestosterone, E2 = estradiol, P4 = progesterone, Testo = testosterone) in relation to sex, Timepoint of plasma collection (base = baseline, i.e. before females and males were joined in aviary; join1 = one day after males and females were joined, nestmat1 = one week later, one day after nest material was provided) and reproductive stages (baseline.nest.stage).
