S1 Table. Ethogram with recorded activities. All behaviors were mutually exclusive. (With
permission adjusted from Engesser, 2011.)
S2 Table. P-values for post-hoc Tukey tests run for factors with significant (or significant
trend) effects.
S3 Table. Demographic group composition of 9 sampled groups during the reproductive
andnon-reproductive season. Focal individuals are marked in bold. The first 2 individuals
listed per group are the dominant individuals. F: Female, M: Male.
S4 Table. Sample dates for data collection of focal individuals.
S5 Table. Individual median close call rate, GCs level, dry fecal weight, mean body weight
and close call rate and dry fecal weight range. rep: reproductive season, nonrep: non-reproductive
season; SUB: subordinate, DOM: dominant; F: female, M: male.
S6 Table. Pearson correlation test for structural close call parameters in relation to fGCM
levels. rep = reproductive season, nonrep = non-reproductive season.
S1 Fig. Correlation of individual mean close call duration per season, and individual
median fGCM level per season. (reproductive (black, dashed line) and non-reproductive season
(white, black line)).
S2 Fig. Correlation of individual mean pulse close call duration per and individual median
fGCM level per season. (reproductive (black, dashed line) and non-reproductive season
(white, black line)).
S3 Fig. Correlation of individual mean IPI close call duration per and individual median
fGCM level per season. (reproductive (black, dashed line) and non-reproductive season
(white, black line)).
S4 Fig. Correlation of individual mean F0 per and individual median fGCM level per season
for the reproductive (black, dashed line) and non-reproductive season (white, black
line).
