Supplemental figure 3. Variation in male aggressive response across types of simulated intrusions (solo male, solo female or mated pair) and between male plumage types (brown vs. red/black, all red/black males subjects were 3 or more years old). All simulated intrusions were done during the female's receptive stage.; Supplemental figure 4. Effect of male age and plumage type on: the male's duet rate with his mate (proportion of female songs the male answered to form a duet) (a), proportion of a male's time present he spent <10 meters from his mate (b), and proportion of the observation the male spent on territory (c), with data split into old and young red-black and brown males. Points show mean ± one standard error. Points with different letters are significantly different at P<0.05.; Two types of Red-backed Fairywren males: philandering red-black male on the left, attentive brown male with a female on the right.; Supplemental document includes detailed methods and four tables. Supplemental Table 1: Results of mixed models, describing the effect of male age/plumage, breeding stage and auxiliary presence on four male mate guarding behaviors: the male's duet rate with his mate, male mate following, male time close to mate and time male spent on his territory. Supplemental Table 2: Results of linear mixed model used to determine how male aggressive response varied with his plumage type (red/black vs. brown), the type of intrusion simulated (solo male, solo female or mated pair) and interactions.Supplemental Table 3: Correlations of 4 behavioral response variables with the first principle component in a principle component analysis. Supplemental Table 4: Results of mixed models, describing number of within-pair, extra-pair and total young sired by each male age/plumage type.
