該音頻有LRC字幕 探索發現:完美捕食(8) 巨大的波塞東龍2015-12-19
Sauroposeidon towers over Deinonychus. In fact, its mammoth size is its primary defense. But this giant begins life very small. For Deinonychus, Sauroposeiden would be a great meal, at least the juveniles, because there would’ve been lots of them and because they would’ve been effectively defenseless.

Attacking another T-Rex may seem like suicide, but a creature with such a voracious appetite has to find food by any means. Cannibalism is the rule. It’s not the exception. If you’re a carnivore and there’s meat there, you take advantage of it.

That’s what it wants to hear, because that sound is gonna mean that’s where lunch is. A battle with Triceratops is more often than not a fight to the death. This herbivore has evolved into a tank. Now, as a Tyrannosaur specialist, I don’t like to admit this, but in that situation, a Triceratops probably won, and it probably won on a regular basis.

Hearing, smell and sight are all well refined. We can look at the sense of vision and see the attributes of a predator. T-Rex’s eyes are 40 centimetres apart providing exceptional binocular vision, the ability to perceive depth.

It’s unlike any other creature that has walked the planet. T-Rex is different. Something about Tyrannosaurs and Tyrannosaurus Rex itself is different than other predatory dinosaurs. But for such a celebrated killer able to take on the toughest creatures of the Cretaceous, some things just don’t add up. It’s slow.
該音頻有LRC字幕 探索發現:完美捕食 Perfect Predators(3)2015-12-17
Triceratops protects itself with a bony shield called a frill. They can fend off an attacker with a pair of one-meter-long swords. You’ve got to crush it. The only way to deal with this huge, curved, cantilevered, composite armor is a crushing blow with multiple teeth. But defeating a Triceratops takes more than just teeth.
該音頻有LRC字幕 探索發現:完美捕食 Perfect Predators(2)2015-12-16
The jaws of T-Rex are infamous and lethal, housing sixty teeth with some as long as 30 centimeters. Its skull is constructed of 64 bones designed to be light but strong. It’s 16 times stronger than the jaws of an alligator. The front teeth are dagger-shaped, with serrated edges designed to tear flesh.

In the Cretaceous Period, dinosaurs rarely die of old age. Predators rule. Their killers engineered for one purpose, attack. Tyrannosaurus Rex was of ten thousand pound, self-propelled, antitank weapon. Now, sixty five million years later, cutting-edge imaging technology lets us look deep inside their bodies to reveal just how the world’s greatest carnivores really work.

This may look like a safari through the African savanna. In fact its a theme park in Florida. And it allows people to experience a world outside their own. In some ways, they are visiting a land from another time.14 thousand years ago, large parts of North Americas landscape and wildlife were just like the savanna of modern Africa.

It’s also a prime hunting ground for red-tailed hawks. And they have the perfect nesting site right next to it. They’d moved in on the top floor of this expensive Manhattan apartment block. It acts like a surrogate tree, supporting their large nest.

It’s incredible that so many birds cram into the tiny spaces underneath the bridge. But the battle for living spaces is now an everyday fact of city life. The most populated North American city is New York. Here space is a precious commodity with more than 8 million people fighting for their share.

But there is at least one place in Florida where the manatees benefit from humans being around. Clean, hot water released from this power plant turns a man-made inlet into a hot tub. And during winter months when sea temperatures drop below 20 degrees centigrade, manatees gather here to keep warm.

This disused car park is a near-perfect location for raising chicks, and only a short flight from a plentiful supply of food. Skimmers get their name from their unusual feeding technique--their extended lower bill detects fish just below the water surface.

Moose mainly browse on trees and shrubs, but they will also sample something new. They have a soft spot for pumpkins left out after Halloween.

Although many of these city foxes do get killed by cars, the population as a whole is thriving. That’s because a regular supply of water means a regular supply of prey, including voles and ground squirrels.

The owls can raise anything from 1 to 12 chicks in a summer season. To survive, their young will have to quickly learn to negotiate the dangers of city life. Longer hunting trips are sometimes necessary as open land disappears. But so long as the city can still provide food and shelter, these owls will remain a part of the urban landscape.

And farming fuelled the growth of another habitat, one that would become an even bigger challenge to North Americas wildlife. The modern city was born. The city is an artificial environment, built around the needs of millions of people, and yet it also offers unexpected opportunities for wildlife.

At first, the Europeans relied heavily on local food supply by native people. But as they settled in, their farming practices began to shape the landscape of North America.

Where purple martins had once laid their eggs in hollow threes, in time, they came to rely almost totally on people to provide nests for them.

By the mid 1800s, the horse and the cowboy had come to symbolize the wild west. And of course, with the cowboys came cattle. As the bison quickly vanished from the landscape, cattle filled their place.

Just over 500 years ago, Europeans arrived in North America. And with these colonizers came an animal that hadn’t been seen here for thousands of years. The horse returned to the Americas, now tamed and carrying the Spanish conquistadors. This new form of transport was rapidly adopted by the native people, which was bad news for some native animals.

and may trace their ancestry all the way back to the first dogs to enter North America. The Carolina dogs are pack animals with a strick hierarchy topped by an alpha male. Like most wild dogs, they hunt in groups. But many of the kills they make are small. Rabbits and small rodents make up a large part of their diet in what can become a collective feeding frenzy.

Saber-tooth died out, but another big cat survived. The puma may have been more able to adapt because its diet is more varied and includes small prey. The grizzly bear also lived through the post Ice Age changes and now thrives in North America.
