Buchanan: Oh, my goodness.
Theyre completley surrounded.
This is your worst nightmare.
It is happening.
Narrator: With night vision 6 times better than humans, they're focused on a target.
Buchanan: The lions have seen the tsessebe.
They're splitting up.
Narrator: To increase their chances, the lionesses have teamed up with more of the pride.
♪ Oh my goodness.
3 subadult males are the most engaged in this hunt.
♪ [Gasps] Your male lions have a reputation of letting the females do all the hard work.
♪ This may be their opportunity to show their worth.
♪ Buchanan: Oh, she's poised.
She's ready to go.
[Lens whirring] Oh, my goodness.
They're completely surrounded.
This is your worst nightmare.
♪ It is happening.
He's running.
Ooh, dopey boy.
You dunder, you messed that up, or did you?
No.
[Screeching] Buchanan: How did you get away from that?
That is one lucky beast.
Buchanan: Oh, they did get one.
Suppose if you're gonna be caught by a lion, be better for you if it was 6 rather than one.
♪ It's a pile-on.
[Grunting] I'm gonna put the drone up, see how many are here.
♪ Look at that.
♪ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
10 lions.
♪ The bigger the lion, the more food they get... ♪ so it's just the 3 young males.
They're getting most of the food because they can muscle in.
[Growling] ♪ Narrator: Pushed off the kill by the subadult males... ♪ the lionesses barely get a bite.
♪ Buchanan: With this number of lions, one tsessebe's not gonna go that far.
That's not really enough to sustain them.
Narrator: The cubs still haven't had the food they need, and it looks unlikely they'll feed tonight.
