The breakdown between stallions, mares and foals captured on Day 5 was added to the gather page.
Foals represented 13.2% of the horses gathered. Of the adults, 41.4% were male and 58.6% were female.
The low percentage of foals may be due to the darting program. The gap between males and females may indicate the sex ratio of the herd is not 1:1 (50/50).
This pattern—more mares captured than studs—has appeared in every wild horse roundup this summer since Onaqui.
Body condition scores were not reported.
