0:00- [Narrator] With the coast clear,
0:02the adults scan the territory for food.
0:06(birds chirping)
0:07The forest is full of deer.
0:11They can be twice as tall and many times heavier
0:14than a single dhole.
0:17But if they work as a team,
0:19the pack can take them down.
0:24And the dholes can use the dense forest
0:27to turn the odds in their favor.
0:33A male chital with large antlers is more likely
0:36to get tangled in the thickets.
0:38(deer yelps)
0:42The dholes edge closer,
0:44talking to each other to coordinate their attack.
0:49But their high frequency calls don't travel far.
0:52(dholes chirping)
0:53The more the dholes disperse,
0:55the more they'll struggle to hear each other.
0:59For a moment, the pack's confused,
1:03but these chatty canids have saved their best talk for last.

1:10The whistle.
1:12(dholes whistling)
1:18A low frequency call,
1:21that carries farther,
1:23and is easier to hear
1:25through the thick forest foliage.
1:29(dholes whistling)
1:34With up to 10 of them surrounding the deer,
1:36the whistling hunters know exactly
1:38where every pack member is,
1:42even when they can't see each other.
1:46At last, they're all in place.
