Earthflight

00:00:24 It's a universal dream to fly like a bird.

00:03:17 an aerial predator of cunning and power.

00:06:12 hoping for yet more opportunities.

00:09:15 The youngsters learn that dolphins follow schools of anchovies.

00:11:56 For a rookie hawk that's just arrived, they're quite a challenge.

00:15:39 Youngsters stick close to their parents...

00:17:45 It still feeds the eagles that are travelling through.

00:19:51 if they are not to miss a great feeding event.

00:22:16 The tide has reached its highest point.

00:24:50 The marshlands of South Carolina are the setting

00:27:54 The young dolphins pick up this technique from their parents

00:44:50 Over one million shore birds arrive from South America

00:47:04 They really do leave no stone unturned

00:49:07 even though their marshlands have been replaced by real estate.

00:50:49 thousands of sockeye salmon

00:53:37 but she has just seconds to spare.

00:55:58 a youngster weakened by her long flight.

00:58:20 we will fly with vultures
