Redsand Canyon Please fill up my soul [Pack Hunt]

Pack hunt! Target Prey: Pronghorn herd of 4-5. Location: Territory #9. Time: Twilight - dusk
Pronghorns can run further and faster than wolves, so an ambush approach will be beneficial. Use the territory to your advantage! 
First round will be planning how to hunt them, then there will be at least two more rounds of actual hunting. Rounds will last for three days with no posting order. So post when you can!
Welcome to the hunt.

The Saints could not survive off of desert pickings forever.
They had to hunt something bigger. More sustainable and will keep them full for a few weeks at least.
Derg set about hunting and herding. Quietly pushing some stray pronghorns deeper into the canyon, which they didn't seem too bothered about.
There were shrubs, a few puddles of mystery water.
They seemed pretty content.

Derg tipped his head, calling for his pack. He knew Hela would be unlikely to participate in the actual hunting, but she could offer up some strategy. He knew these things were fast, and could probably run further than them. Ungulates often could with their migrations and all.

He waited for his packmates to swarm on him. They must be hungry, for blood or food.
"Any strategies for catching fast ungulates?" He questioned when a suitable amount of wolves arrived. It would do good for them to collaborate and learn from each other. He caught birds best, so he'd see what they came up with.
