How would you feel about eating deep fried locusts, ant egg salad or barbequed tarantulas? This documentary sees presenter and food writer Stefan Gates immerse himself in the extraordinary world of hardcore insect-eating in a bid to conquer his lingering revulsion of bugs and discover if they really could save the planet. With 40 tonnes of insects to every human, perhaps insects could offer a real solution to the global food crisis - where billions go hungry every day whilst the meat consumption of the rich draws vast amounts of grain out of the global food chain. Stefan's on a mission to meet the people in Thailand and Cambodia that hunt, eat and sell edible insects for a living. But nothing quite prepares him for bug farming on this terrifying scale, from stalking grasshoppers at night to catching fiercely-biting ants. And it's not just insects on the menu. Stefan also goes hunting for the hairiest, scariest spider on the planet - the tarantula. Stefan asks if the solution is for everyone - the British included - to start eating insects too.

The Making of the Garden: Attenborough opens the series at the Dead Sea, where the hot climate and intense evaporation mimic conditions that were replicated on a much larger scale when the newly formed Mediterranean basin dried out. Around 5.5 million years ago, the Atlantic flooded the basin, allowing marine life to recolonise the new sea. Mountains became islands: some of them volcanic, others formed of limestone. Common species marooned on these islands evolved into new varieties. In a Maltese cave, Attenborough discovers fossil teeth from dwarf elephants. Most are only known from fossils, but one species, the Mallorcan midwife toad, has recently been discovered. Attenborough abseils down to a secluded pool to find it. In Europe, blooming wildflowers signal the arrival of spring. This triggers the emergence of insects, and in turn, the arrival of insectivorous birds such as rollers and bee-eaters. After the Mediterranean Sea formed, the climate continued to warm, forcing many birds to extend their migration routes between Europe and Africa. Exotic arrivals include spoonbills, white storks and flamingos. Reptiles are most active during the hot summers. Attenborough catches a Montpellier snake and describes its hunting behaviour. Some creatures, including chameleons, crested porcupines and fruit bats have colonised Europe from Africa. Rock hyraxes, which have reached Israel, may soon join them. The arrival of humans, 28,000 years ago, is known from flint tools and rock etchings found in Spanish caves. Later cliff paintings demonstrated that Mediterranean man was still living in hunter-gatherer societies 10,000 years ago, but that would soon change.

The Gods Enslaved: Attenborough explores the influence of the first Mediterranean civilisations, placing the symbolism of the bull at the centre of his narrative. Cave paintings in France and Spain and Egyptian hieroglyphs both reveal cultures that revered the wild bull for its fertility and strength. The Ancient Egyptians deified many animals, including the living bull-god Apis, and accorded it the same ceremonial burial as their Pharaohs. Attenborough describes the ritual from the Temple of Apis in Memphis. At Saqqara, more than 4 million mummified sacred ibises were brought as offerings by devotees. Crop cultivation began in the Nile Delta, but the Minoans were the first to harvest olives, using oxen-powered mills to crush them. They were also skilled fishermen, whose traditional methods for catching octopus and tunny are still practised by modern North Africans. Attenborough explains how Cretan men pitted themselves against bulls in specially built arenas. The Romans were passionate hunters, using wild animals ransacked from their Empire for entertainment, but they also held the bull in special regard. The statue of Artemis, salvaged from the Temple of Ephesus, is adorned with bulls' testes. Of more than 600 Roman cities along the North African coast, Leptis Magna was the greatest. Its wealth was built on trading livestock and produce harvested from the surrounding fertile lands; figs, olives and grain. But in deforesting the land the Romans precipitated their own demise. Although humans had enslaved and subdued the bull, Attenborough concludes that they had yet to learn the value of the natural world.

The Wastes of War: The relationship between man and horse has a long history in the Mediterranean region. A passion for horses spread west from Central Asia, but took a while to become established as a pastoral way of life returned. The Roman Empire was replaced by marauding Huns, Visigoths and Vandals. In the seventh century, Arabian cavalrymen took Jerusalem and arrived in Spain to spread the word of the Qur'an. They established bases at Córdoba and Granada, bringing orange trees and peacocks for the gardens of their impressive mosques. The Arabs brought their falconry skills too. The birds are used to this day to catch desert animals such as hares and Houbara bustards. Many attitudes towards animals stemmed from pre-Christian beliefs. Fire salamanders were suspected of having magical powers, while the mandrake was thought to be deadly to those who harvested its roots. Even today, Cocullo holds an annual festival of snakes, the animals thought to bring protection. Attenborough visits the impregnable Krak des Chevaliers in Syria to discuss the Crusades. Black rats carried on the retreating Christian army’s ships spread plague through Europe, killing a third of the population. During the Middle Ages the forests of Southern Europe were cleared. Attenborough discusses the deforestation caused by Spanish Merino sheep grazing and the Venetian shipbuilding industry. Despite the advent of the internal combustion engine, horses still play an important role in European culture. The final scenes show thoroughbreds racing at Newmarket and a performance by the Spanish Riding School in Vienna.

Strangers in the Garden: The final episode examines man's impact on the Mediterranean during the twentieth century. Attenborough dines on red soldierfish in Cyprus, one of a hundred or so species to have colonised the Mediterranean from the Red Sea, via the Suez Canal. Other invaders have been less welcome. The Phylloxera aphid from North America attacked French grapevines, and only by importing insect-resistant rootstock from the USA was a total catastrophe averted. The growth of tourism has led to uncontrolled development of hotels and marinas, squeezing out natural inhabitants of the coast such as Mediterranean monk seals and loggerhead turtles, who come ashore to lay their eggs. The sea is in danger of becoming barren due to overfishing and pollution. Attenborough dives beneath the surface to demonstrate the difference between a thriving seagrass ecosystem and one smothered in sedimentation from untreated sewage. Meanwhile, in Egypt, he looks at the damaging effects of damming the Nile, which include reduced productivity, a collapse of Egypt's sardine fishery and population displacement. The shooting of millions of migrating birds, draining of wetlands and deliberately started wildfires add to the pressures on the natural world. There are, however, still a few places where the Mediterranean has been left unspoilt. One is Plitvice in Croatia, whose mixed forests provide shelter for many creatures driven or hunted out elsewhere. In the uninhabited Sporades Islands east of mainland Greece, Mediterranean rarities such as Audouin's gull, Eleonora's falcon and the European black vulture can still breed freely.

A female Velociraptor named White Tip is walking on her own in the desert, after her family has been killed by another pack, and she must find a new one. She tries to hunt Prenocephale, but fails, as she cannot efficiently hunt without a pack. She then turns to hunt smaller prey like lizards. During one of her hunts, White Tip hears a loud scream of an Oviraptor and heads to the location. When she gets there, the Oviraptors are in a mating ritual, where a young male tries to seduce the female with his plumage, but it doesn't work. Then an older male arrives and evicts him. Heavily ticked off by his defeat, the young Oviraptor unleashes his wrath on White Tip, who runs away.

One of them is Pod, a male Pyroraptor, and his sisters. The narrator explains that their species relies on their brain power to survive. He goes on to explain that the island has been hit by a series of recent earthquakes and as he speaks, one hits. It scares Pod and his sisters, but the quake soon stops without causing injury to any of the dinosaurs. As Pod's group heads in the dense forest, away from a noisy herd of Titanosaurus Pod finds a carcass of a small Iguanadon. As he eats, a pair of carnivorous Tarascosaurus are approaching, attracted by the scent of blood. Pod and his sisters close in to defend their meal. In the middle of the battle, another earthquake hits, knocking Pod unconscious. The male Tarascosaur, off balance, trips on a tree root and breaks his leg. His cries of pain wake up Pod and he and his sisters drive the female Tarascosaur off. Before they can kill the male, an Iguanadon stampede forces them to flee to the shoreline. At shore, the earth quake creates a tsunami that sweeps Pod and the other dinosaurs away. Pod and one of his sisters survives, clinging to life on a log. The next day, however, Pod's sister is eaten by a Elasmosaurus.

The story starts in Late Cretaceous Montana, filled with active volcanoes. The narrator states that the Rocky Mountains are being formed with volcanic eruptions. Elsewhere in the highlands, a herd of Orodromeus is grazing on the wheaty grasses. As they graze, a trio of Troodon sneak up from the shadows and ready themselves to pounce. But before they can do so, the lookout spots them and sounds the alarm. The Troodon chase after them. However, they slow down on a rocky hill because they can't afford to break their claws in such a reckless race. Suddenly, the ground quakes. As they ponder the situation, one of the trio members is blasted sky-high by a geyser impact, then crashes down, dead. Their hunt ends with disastrous results, and the remaining Troodon turn tail and make a break for it.

2010; We have an extraordinary relationship with dogs - closer than with any other animal on the planet. But what makes the bond between us so special? Research into dogs is gaining momentum, and scientists are investigating them like never before. From the latest fossil evidence, to the sequencing of the canine genome, to cognitive experiments, dogs are fast turning into the new chimps as a window into understanding ourselves. Where does this relationship come from? In Siberia, a unique breeding experiment reveals the astonishing secret of how dogs evolved from wolves. Swedish scientists demonstrate how the human/dog bond is controlled by a powerful hormone also responsible for bonding mothers to their babies. Why are dogs so good at reading our emotions? Horizon meets Betsy, reputedly the world's most intelligent dog, and compares her incredible abilities to those of children. Man's best friend has recently gone one step further - helping us identify genes responsible for causing human diseases.

A massive winged creature has been captured and killed near the Amazon jungle. Reports state that the army were sent in after local villagers complained of a huge flying creature, bigger than a man, terrorizing and attacking livestock, and small children. After the creature was killed, it was put on display so the nearby locals could see their nightmare was over. Some residents claim this was a Mothman type creature while others state its nothing more than a mutated bat.

Broadcast 21 October 1998, the first episode looks at how birds first took to the skies in the wake of the insects. It begins in Mexico, where Attenborough observes bats being outmaneuvered by a red-tailed hawk. Pterosaurs were the birds' forerunners, some 150 million years after dragonflies developed the means of flight, but eventually went extinct together with the dinosaurs. Birds had by then already evolved from early forms like Archaeopteryx, the first creature to possess feathers. Its ancestry can be traced through reptiles, and some current species, such as the flying lizard, possibly show paths this evolution may have taken. One of the biggest birds to have ever existed was the terror bird, which proliferated after dinosaurs vanished and stood up to 2.5 metres tall. By comparison, the ostrich, while not closely related, is the largest and heaviest living bird. It was probably the evasion of predators that drove most birds into the air, so their flightless cousins evolved because they had few enemies. Accordingly, such species are more likely to be found on islands, and Attenborough visits New Zealand to observe its great variety, most especially the kiwi. Also depicted is the moa, another huge creature that is now gone. The takahē is extremely rare, and high in the mountains of New Zealand, Attenborough discovers one from a population of only 40 pairs. Finally, another example on the brink of extinction is the kakapo, which at one point numbered only 61 individuals. A male is heard calling — an immensely amplified deep note that can be heard at great distances from its nest.

Broadcast 28 October 1998, the second programme deals with the mechanics of flight. Getting into the air is by far the most exhausting of a bird's activities, and Attenborough observes shearwaters in Japan that have taken to climbing trees to give them a good jumping-off point. The albatross is so large that it can only launch itself after a run-up to create a flow of air over its wings. A combination of aerodynamics and upward air currents (or thermals), together with the act of flapping or gliding is what keeps a bird aloft. Landing requires less energy but a greater degree of skill, particularly for a big bird, such as a swan. Weight is kept to a minimum by having a beak made of keratin instead of bone, a light frame, and a coat of feathers, which is maintained fastidiously. The peregrine falcon holds the record for being fastest in the air, diving at speeds of over 300 km/h. Conversely, the barn owl owes its predatory success to flying slowly, while the kestrel spots its quarry by hovering. However, the true specialists in this regard are the hummingbirds, whose wings beat at the rate of 25 times a second. The habits of migratory birds are explored. After stocking up with food during the brief summer of the north, such species will set off on huge journeys southwards. Some, such as snow geese, travel continuously, using both the stars and the sun for navigation. They are contrasted with hawks and vultures, which glide overland on warm air, and therefore have to stop overnight.

Broadcast 4 November 1998, the next installment focuses on dietary needs and how different species have evolved beaks to suit their individual requirements. The latter come in a multitude of forms. Blue tits and goldfinches have beaks akin to tweezers, with which to extract seeds, while the hawfinch's razor-like bill can deal with a cherry-stone. However, the crossbill is the only finch that can twist its mandibles in opposite directions. Jays store acorns for winter by burying them in the ground, whereas woodpeckers can keep up to 60,000 of them in one tree trunk. Sap is also desirable, and there are a variety of methods used to obtain it. The hoatzin is the only specialised leaf-eater, and accordingly has a digestive system more akin to that of cattle. Plants recruit birds to aid pollination, and offer nectar as a reward. Hummingbirds eat little else, and the sword-bill's beak is the longest of any bird in relation to its body. Insects are also highly prized, and Galápagos finches are shown to possess some ingenuity as they not only strip bark, but also use 'tools' to reach their prey. Crows are hailed as being among the most intelligent birds, and one is shown using a twig to spear a grub within a fallen log. The robin is an opportunist, and Attenborough observes one seizing morsels as he digs a patch of earth. In South America, a cattle tyrant sits atop an obliging capybara and uses its vantage point to spot passing food that may be dislodged by its grazing partner.

Broadcast 11 November 1998, this episode examines those birds whose sustenance comes from flesh and their methods of hunting. In New Zealand, Attenborough observes Keas, parrots that do not eat meat exclusively, raiding a shearwater's burrow for a chick. However, it is the dedicated birds of prey, such as owls, buzzards, eagles, falcons and vultures, to which much of the programme is devoted. In order to spot and pursue their victims, senses of sight and hearing are very acute. Vultures are the exception, in that they eat what others have left, and once a carcass is found, so many birds descend on it that the carrion seems submerged beneath them. The Turkey Vulture is an anomaly within its group, as it also has a keen sense of smell. Eagles defend their territory vigorously, and a pair of sea eagles are shown engaging in an aerial battle. The Galápagos Hawk hunts Marine Iguanas, but can only do so when its quarry is vulnerable, during the breeding season. The African Harrier Hawk has adapted to extracting burrowing animals by virtue of an especially long, double-jointed pair of legs. By contrast, a shrike is not equipped with the requisite sharp beak and talons needed for butchery, and so dismembers its kill by impaling it on the thorns of acacias. The Lammergeier eats bones, and will drop them on to rocks from a great height in order to break them down to a digestible size. Also featured are the Eurasian Sparrowhawk, Goshawk and Peregrine Falcon.

Broadcast 18 November 1998, the next programme details river and ocean dwellers. The dipper swims completely below water to search for food, whereas the kingfisher uses a 'harpoon' technique, diving from a vantage point. However, the darter uses a combination of both methods, stalking its prey underwater before spearing it. By contrast, the reddish egret uses a kind of dance to flush out the aquatic inhabitants. Skimmers have different-sized mandibles, the lower one being used to skim the water's surface for small fish. Ducks have developed an assortment of angling skills. Some dabble, like the mallard, while others are of a more streamlined design and are at home underwater, such as the merganser. Waders, which specialise in feeding on mud flats at low tide, include avocets, godwits, dowitchers and sanderlings. The pelican feeds in groups, their pouch-like bills being more successful when used collectively. Boobies fish in the open ocean and are shown dive-bombing shoals en masse. Attenborough visits Lord Howe Island, off Australia, and by imitating the calls of various birds, invites a group of curious Providence petrels — which are indigenous — to investigate. Because there are no humans in their habitat, they are a very trusting species, as Attenborough discovers when one perches on his hand. Out on a seemingly empty area of ocean, the presenter is able to fill it with various sea birds within seconds, simply by throwing fish oil on to the water.

Broadcast 25 November 1998, this installment describes ways of communicating. A colony of fieldfares in Sweden deters a raven from raiding a nest by collectively raising an audible alarm. However, in an English wood, all species co-operate to warn each other surreptitiously of approaching danger. By contrast, a sunbittern is shown expanding its plumage to discourage a group of marauding hawks. The members of the finch family exemplify how colour aids recognition. Birds have excellent colour vision, and the feathers of many species react to ultraviolet light. Flocking birds, such as sparrows, also have a 'ranking system' that determines seniority. In Patagonia, Attenborough demonstrates the effectiveness of sound: he summons a Magellanic woodpecker by knocking on a tree. The nature of tropical rainforests means that their occupants tend to make much louder calls than those in other habitats, and several such species are shown. Saddlebacks vary their calls so that even individuals from different areas can be identified. The dawn chorus provides a mystery, as there is still much to learn about why so many different birds sing together at the same time of day. (Proclaiming territory or attracting mates are two likely reasons.) Finally, Attenborough introduces the Superb Lyrebird as one of the most versatile performers: it is a skilled mimic, and this particular one imitates not only other species, but also cameras, a car alarm and a chain saw.

Broadcast 2 December 1998, this programme discusses mating rituals. If a male bird is on the lookout for a partner and has a suitable nest, it must advertise the fact, either by its call, a visual display or both. The frigatebird provides an example of the latter, with its inflated throat pouch. The hornbill's courtship, among that of many others, also runs to the offer of a gift. For some species, dancing can also be an important component, and grebes are shown performing a pas de deux. The cock-of-the-rock, which dances solo within a group, is contrasted with the team performance of the manakin. Once trust has been established between a pair, mutual preening can follow. After mating, the individuals usually remain together to rear their eventual family. In this regard, the rhea and the phalarope are highlighted as unusual because in both instances, it is the male that incubates the eggs. Some females judge a prospective companion on its nest-building ability, and this is a conspicuous part of the weaver's behaviour. The bowerbird puts on one of the most elaborate displays: a hut-like construction, completed by a collection of objects designed to impress. Competition among males can be fierce and in Scotland, Attenborough observes rival capercaillies engaging in battle — after one of them chases the presenter. Avian polyandry is not widespread, but is illustrated by the superb fairy-wren, where the male's family can easily comprise young that it did not father.

David Attenborough explores the extraordinary variety of ways in which birds from all over the world construct their nests and protect their eggs from predators. Because birds need to be light in order to fly, each egg must be laid as soon as it is produced and then kept both warm and protected. So the vast majority of birds make nests of some kind. Australian warblers use their beaks like a sewing machine to stitch leaves together, and apostle birds use them to trowel mud on their nests.
