Parameters used in analysis of male mate choice as a function of swelling size. Days since last wet month (denoted with *) is distributed bimodally. All other variables conform to normality.

Cycles since resumption	Number of cycles since resumption	2 – 8	3.81 ± 1.56
Female age	Female age (to nearest tenth of a year)	7.1 – 18.3	12.09 ± 3.24
Female rank	Female dominance rank	1 – 27	11.05 ± 6.56
Days since last wet month	Number of days since last wet month	0 – 320	*100.43 ± 119.34
Average queue length, days d-5 to d-1	Number of adult males in the queue (# adult males in the group - # cycling females), averaged over the 5-day window.	0.4 – 17	11.01 ± 4.19
