Nearly a dozen wild horses died in the first 10 days of a big mustang roundup in Nevada, and Rep. Dina Titus, D-Nev., is calling the deaths tragic proof of the need to outlaw the use of helicopters to capture the animals on federal land.

The 11 deaths include five young foals, four horses with broken necks and a stallion with a snapped rear leg that was chased by a helicopter and horseback rider as it tried to flee on three legs for 35 minutes before it was euthanized, according to witnesses.

Titus said the deaths should serve as a wake-up call. “A horse with a broken leg was chased in the sweltering heat by a helicopter,” she said, criticizing a Bureau of Land Management practice the she is trying to ban through House legislation.

“This latest instance of BLM mistreatment of Nevada’s wild horses is tragic,” Titus said Tuesday.

Nevada is home to nearly two-thirds of the 68,928 wild horses the bureau estimated on March 1 were roaming federal lands in 10 Western states stretching from California to Montana.
