It examines animal behaviour in all its infinite variety and in doing so we are allowed to witness some of the most enchanting animal personalities, as well as some of the most fearsome. Attenborough hails the species as the consummate home maker, and explores a 15-foot colony in West Africa that contains 1. The web of the orb spider is hailed as one of the most elegant food catching devices, and the methods of two others, nephila and its kleptoparasite visitor, argyrodes, are explored in detail. Compatible with various Adaptive Technology software, including screen readers. The termites' intricate creations allow for security, heating, air conditioning, self-contained nurseries and gardens, and sanitation systems. The exercise is all the more hazardous since the species is a land crab, and the eggs have to be deposited in the sea - where the most ancient animals on the planet still live and breed. There are no holds barred between rival zebras: kicking and biting is employed until a victor emerges, whereas giraffes slam their necks against each other.
Some fish regularly clean others, and wrasse and shrimp appear to specialise in this regard, as do remora, which permanently hang on to their hosts. With leaves defended by poisons and seeds clad in thorns, animals fight back in very innovative ways. Please set an alarm and add The Trials of Life to your favourites, so we can remind you by email when there's a new episode available to watch. Finally, tropicbirds, their crops full with food en route back to their nests, are ambushed in mid-air by a group of frigatebirds, whose aim is to make them surrender their cargo. Air Date : 8th-Nov-1990 This episode focuses on those species that co-operate and depend on or exploit others. Male sea lions are shown fighting over a harem, and some use the battle to their advantage by making off with reluctant females. Attenborough starts in Africa at dusk, by describing some of the species that don't rely on sight.
Finally, Attenborough stands on a waterfall in Ireland to tell of the three-year, 10,000-kilometre journey made by elvers. Large herbivores that have horns or antlers are naturally inclined to use them to assert their dominance over the females in a herd. We provide no support for third party add-ons installed on your devices, as they do not belong to us. Part 4: Hunting and Escaping Life-and-death duels are fought daily in the wild: an orchid turns out to be a predator, killer whales ambush sea lions and chimps pursue colobus monkeys. In terms of the facts there was a very good mix of the known ones and the unknown, some facts being familiar to us while also dealing with very complex and very much relevant issues with tact. Their emergence as their innovative hunting techniques and physical advantages enable them to dominate their habitats. The arrival of the new cats; early snow leopards, cheetahs, and jaguars, marked a turning point in the evolutionary track.
African hunting dogs are shown hunting gazelles, of which the target is the individual that leaps lowest. Because it needs to transfer to a bird's gut to develop further, it causes the snail to advertise its presence to allow itself to be consumed - thus completing the circle. Attenborough visits the Sahara to illustrate a species that makes the longest overland journey of any insect: cataglyphis, an ant that uses the sun's position to enable it to return to its nest in a straight line. Mammals shown giving birth to fully formed young include wildebeest, antelope, sea lions and chinchillas. Air Date : 13th-Dec-1990 The final installment illustrates how species fulfill their ultimate raison d'être and ensure that their genes are passed on to the next generation.
Burrows and holes can provide considerable refuge, and Attenborough inspects the home of the American prairie dog, an elaborate construction that has its own air conditioning system. Whales sing to their prospective partners, and the female's calls can be heard by suitors for over eight kilometres. Other plants use food or nectar as a bribe to get their pollen transported, and several species of hummingbird have developed exclusive relationships with certain of them. In Kenya, Attenborough accompanies a tribesman who calls to a honeyguide, which in turn answers him and leads the pair to a bees' nest. This episode concentrates on animal communication.
Air Date : 6th-Dec-1990 This programme surveys the methods employed in attracting a mate, mainly those of birds. In order to gain attention, it 'trampolines' in the same spot for up to 400 times a day. The tribesman extracts the honey, and some is left to reward the bird. David Attenborough is nothing short of a national treasure. In 80% of cases this turns out to be true. However, none of these methods of protection pose problems to army ants, which can subdue any of their prey, simply by virtue of their size and vast numbers. Found myself really caring for what we're told, the animals and their trials.
Your use of this version of Genome is covered by the and these terms. Their utterances are effectively words: a vocabulary that defines each of their predators, so an alarm call is specific to a particular threat. Part 1: Arriving An examination of the diverse techniques employed by animals to disperse and protect offspring. Part 3: Finding Food The search for food in the animal world. Finally, Attenborough swims with dolphins. Scorpions carry their young on their backs, while a shrew will leave hers under a stone while she goes to feed. Attenborough begins in the South American rainforest, where the proliferation of animal and plant life does not necessarily make it easy to find food.
He highlights the elephant seal as an animal that experiences a compressed childhood, being abandoned after three weeks and left for up to another eight alone, while it becomes large enough to be able to swim. The beaver is responsible for one of the biggest animal dwellings: its wooden lodge that rises from the river bed stays in place from one generation to the next, and so requires constant maintenance. Air Date : 11th-Oct-1990 The next installment is devoted to the ways in which animals gather their sustenance. The music score fits very well, never overly grandiose while never being inappropriate. Dwarf mongooses live in family groups of around a dozen. This episode demonstrates that nature's solutions are as varied as those in human society. Their utterances are effectively words: a vocabulary that defines each of their predators, so an alarm call is specific to a particular threat.
A female chinchilla is even more so, and rejects an unwanted suitor by squirting urine in its face. Albatrosses must be accomplished fliers as soon as possible - chicks are shown being hunted by tiger sharks. Silk is such a valuable commodity that those that can't make it steal it instead. Meanwhile, some of the most extreme co-operation is demonstrated by the underground naked mole rat, whose 80-strong clusters are divided into workers who tunnel perpetually , soldiers who only act when danger threatens , and a single queen for breeding.
