SAVING THE SIERRA BIGHORN

0:01
I've traveled to California's Inyo National Forest, about to meet the Wildlife Conservation Team who monitors and protects endangered Sierra Nevada bighorn sheep.

0:12
We monitor the mortality factors, whether it's severe winters, disease or predation on the population.

0:21
These are not your typical sheep.

0:24
They're agile athletes who survive in the most extreme environments, and in order to keep track of their health, extreme efforts must be taken to capture and survey them.

0:39
Mutual of Omaha's Wild Kingdom first highlighted the amazing conservation story of bighorn sheep in the mid 1970s.

0:49
This relocation project proves that game animals can be preserved and their range expanded.

0:57
50 years later, we're still using helicopters to capture and assess sheep.

1:03
In fact, it was Wild Kingdom that inspired the expert helicopter pilot leading the mission today.

1:10
I watched Mutual of Omaha Wild Kingdom every Sunday night.

1:14
They used helicopters a lot.

1:16
And I always want to be a helicopter pilot, you know, And I always thought maybe someday I could work with wildlife, if I could combine that, you know, that's pretty much the ultimate job.

1:30
The only way to monitor bighorn sheep is by capturing them with a helicopter.

1:35
Jim's going to show me what it takes to save these animals from up in the air.

1:40
I have a lot of respect.

1:41
I've personally never been up in a helicopter before.

1:44
So what you all do is just, it's amazing.

1:46
Well, the backside of the Sierras is a very dangerous place to fly when it's windy.

1:52
So we're going to go check the wind up there and see if we can get a round of capture going.

1:57
So if you'd like to go in a helicopter, this would be a good opportunity.

2:03
All right, well, who's got my helmet?

2:13
After my stomach catches up with my body, I can appreciate the view.

2:17
Oh my gosh, it's amazing that we're so hot.

2:21
Hi, this is so the wind where we are right now is fine.

2:28
That's what you're saying.

2:29
But it's all about when you go higher and higher, correct?

2:33
And we're working the side of the mountain range, which is the most feature.

2:40
We're at the tools that get the sheep to the biologist.

2:44
60% of the Sierra Bighorn sheep are over 12,500 feet.

2:50
Working at those altitudes, you better be on your A game.

2:55
I'm feeling a lot of wind here, huh?

2:59
It's still workable for us.

3:05
The wind conditions are workable and we've located a herd.

3:09
Now it's time for the capture team to do their job.

3:20
Jim leads a fearless crew known as Muggers.

3:25
They jump out of the helicopter and actually wrestle the animal to the ground, hobble them up, get the Nets out and they do all the tough, hard work.

3:36
We're sent out with a general mission in this area they want to use and a ram.

3:42
Once we locate the animal, the pilot will then move them into a spot that is safe to capture.

3:50
Hanging out of the helicopter.

3:52
The mugger prepares to net the animal.

3:57
Soon as that comes out, you have no more control over the situation.

4:05
Low level flying like this leaves no room for error, but it's also critical to the safe handling of these animals.

4:13
A lot of people won't even land at 12,000 feet.

4:16
We're up there working and maneuvering, putting people out, putting sheep in and actually working at those altitudes after they're caught.

4:28
These animals are delivered to the team of biologists waiting at the camp, started far in the distance for the helicopter's bright red.

4:39
We could see it getting closer and closer with four little bundles hanging off the bottom, almost like Jingle Bells, right?

4:47
Hanging off with four bighorn sheep.

Watch as conservationists go to new heights in pursuit of protecting the Sierra Nevada bighorn sheep.

An epic saga of courage and compassion, where science meets adventure. Peter and Dr. Rae head to California’s rugged Sierra Nevada to join conservationists who risk life and limb to protect one of North America’s most endangered species — the Sierra Nevada bighorn sheep. From dizzying altitudes and perilous cliffs, a fearless team captures, collects vital health data and fits GPS collars on these elusive animals. The journey then shifts to the deserts of Anza-Borrego, where another herd of bighorns faces searing heat and relentless drought. Through ingenuity, teamwork and sheer determination — from airlifts of 2,000-gallon water tanks to intimate ultrasounds revealing new life — Peter and Dr. Rae take part in the fight to protect a symbol of the American West.
