Adobe Town Roundup Ends

The incident concluded on August 2 with 1,676 horses captured, 1,664 shipped, two released and seven dead according to figures in the sidebar.

There were three unaccounted-for animals.

1,676 – 1,664 – 2 – 7 = 3

The capture total does not include a mule caught on July 21.

The capture and removal goals were 1,675 each.

The daily reports indicate eight deaths, revised downward from nine, for a death rate of 0.5%.

The average daily take was 88.2.

Foals represented 21.2% of the animals gathered.

Of the adults, 45.6% were male and 54.4% were female.

There were no plans to treat any of the mares with fertility control pesticides and return them to the range.

The HMA is subject to permitted grazing.

The operation liberated 20,088 AUMs per year.

Unsolved Mystery: Chincoteague Pony Demographics

Assuming that foals are produced by a simple random process centered at 50% males / 50% females, a herd of 150 adults should contain between 37.75% and 62.25% females according to this relationship, where n = 150 and p-bar = .5.

Converting to integers, the number of female adults should range between 57 and 93.

Given that twins are very rare for horses, a herd of 150 adults should not be able to produce 100 foals unless something has occurred that invalidates the assumption of 50% males and 50% females.

Your host sent an email to the Chincoteague Volunteer Fire Company this morning seeking the current size of the herd and the number of adult males and females.

Miracles and Wonders on Assateague Island

How could a herd of 150 adults, on the Virginia side of the island, produce 100 foals?

Fifty stallions covering 100 mares with a 100% success rate?

Twenty-five stallions covering 125 mares with an 80% success rate?

Have the saltwater cowboys been skewing the sex ratio in favor of females?

All six of this year’s buy backs are fillies according to the auction results.

Ka-ching, ka-ching.

Foals are hard to find on the Maryland side because the mares have been ruined by PZP.
