Return of the Desert Bighorn (2018)

After all native desert bighorn sheep were eliminated from Texas by the 1960s, conservationists began the long fight for their return. Now, after many years of hard work and trial and error, healthy populations roam parts of the state. Return of the Desert Bighorn follows wildlife biologists as they capture, collar, and relocate desert bighorn to restore populations in West Texas.

Unfortunately the movie Return of the Desert Bighorn is not yet available on HBO Max.
