BLM said today that the operation was complete, with 1,196 horses gathered, 26 deaths and 1,139 horses shipped.
The number of horses returned to their home range was 43, according to the news release, which is not possible given the previous data.
If 21 mares were treated with contraceptives prior to release, they would have to be joined by ten studs, for a total returned of 31.
The goal was 1,225 horses gathered with 60 returned.
