No horses were caught on Days 14 and 15.
The trap and temporary holding pens were moved to another undisclosed location on Day 15.
The contractor dispatched a mare on Day 14 due to low body condition score and loss of teeth.
The death rate is 3.3%.
The capture total includes 168 stallions, 235 mares and 45 foals.
Youngsters represented 10.0% of the animals gathered, consistent with a growth rate of five percent per year.
Of the adults, 41.7% were male and 58.3% were female, suggesting the herd has an abnormal sex ratio.
The HMAs and surrounding lands are subject to permitted grazing.
*According to advocates.
Day 15 ended with no unaccounted-for animals.
Mares returned to the Complex will be treated with GonaCon Equine, a fertility control pesticide. As of today, all returned animals have been stallions.
