Plasma LH levels, average cumulative frequency of aggressive courtship behavior (bow-coos and hop-charges), and average cumulative duration of nest solicitation behavior (wing-flipping) in males paired with females (courting males) and control males that remained in isolation cages (isolated males) during a 1 h (Experiment 2) or 2 h (Experiment 1) exposure period. Values are mean ± SE.
