- Target: Burros

The cumulative total includes 391 jacks, 508 jennies and 109 foals, based on figures in the daily reports. The breakdown at the gather page is 392, 506 and 110.
Youngsters represented 10.8% of the animals captured. Of the adults, 43.5% were male and 56.5% were female.
The percentage of foals has been going down as the number of animals caught goes up.
The herd can’t be growing at a rate of 20% per year with a birth rate of 11% per year.
The percentages of males and females are still outside the range of expected variation for a simple random process centered at p-bar = .5 (50% males / 50% females) with a sample size of n = 899 adults.
Abnormal sex ratios are not unusual in herds subject to the Montana Solution.
The report for Day 19 said that burros in the HSUS darting experiment were treated at the holding facility.
The location of the trap site within the HMA was not given.
Day 21 ended with 212 unaccounted-for animals.
With 1,008 burros taken off the range, the removal goal is 93% complete.
