For many of the behaviors, it was difficult to find significant evidence that there was a change in the behavior frequency compared to the control. There is so much covariation in the behaviors that it is often hard to see patterns in graphs, but we still have found some significant changes in certain behaviors.

Boxplot of the total time the nesting males spent fanning during the 10-minute observation period, in the Pre, Post1, and Post2 time points after being injected with control-saline, isotocin (IT), or an isotocin antagonist (IT-antagonist).

There was significantly less of an increase in fanning in males injected with isotocin in post 1 compared to the control (p = 0.01622). No significant effects of the antagonist on fanning behavior.

Boxplot of the total amount of times the nesting males chased the satellites during the 10-minute observation period.

There is more of a drop in NM chasing the SAT from Pre to Post 1 for NM injected with the antagonist compared to the control (p = 0.03446). There was no significant effect of isotocin.

Boxplot of the total amount of times the satellites submitted to the nesting males during the 10-minute observation period.

There is more of a decline from Pre to Post 2 in satellite males submitting to the nesting male in individuals injected with isotocin compared to control saline (borderline significant, p = 0.0569). There is no effect of the antagonist.

Boxplot of the total amount of times the nesting male spawned with a female during the 10-minute observation period.

There is no significant effect of treatment on the NM spawning behavior.

Boxplot of the total amount of times the nesting males chased the sneakers during the 10-minute observation period.

There is no significant effect of treatment on NM chasing sneakers.

Boxplot of the total amount of times the nesting males followed the females during the 10-minute observation period.

There is no significant effect of treatment on NM following females.
