“Most roundups, years ago, didn’t have the pens like we’ve put up here,” Cattoor said. “We bring them in, and we separate them as soon as we can. Not too quick, but the quicker we get them separated, the easier it is on the horses. It helps stop their fighting and keeps them from getting people and horses hurt.”

The pen is designed to lower stress levels among the animals.

According to BLM wild horse and burro specialist Jay D’Ewart, the helicopters also provide a less stressful method than roundup practices of the past.

“The helicopter is easier on the horses because they can get them going in the general direction and back off and let them trot,” D’Ewart said. “If you’re trying to run them with horses, you’re putting a lot of people and animals in harm’s way.”

The dust settled as the helicopter crested the hill following two mustangs over the far side of the bowl. The black mustang turned and trotted wearily away from the sound of the chopper.

After a short break, the horse settled into its surroundings. He continued his escape from the ruckus caused by the annoying flying machine. The horse had likely seen a helicopter before and was savvy to the trapping strategies at hand.
