Bird Migration Reading Passage 

You should spend approximately 20 minutes answering Questions 1 – 13 based on the Reading Passage below. 

                                                       Bird Migration

1. Birds’ various distinctive design elements allow them to pull off such astounding endurance feats. They have hollow, light-weight bones, intricately patterned feathers that provide thrust and lift for swift flight, navigation systems that are far superior to those created by humans, and a clever heat-conserving structure that, among other things, emphasises all blood circulation below layers of warm, water-resistant plumage, making them capable of surviving in the harshest climates. Their respiratory systems must function effectively during prolonged altitude flights, thus they have an oxygen extraction system from their lungs that is significantly superior to that of any other mammal. Their bodies can build up significant amounts of fat throughout the later stages of the summer breeding period, when food is abundant, to give them enough energy for their lengthy migratory trips.
   
2. Finding enough food during the winter, when it is scarce, is the primary driver behind bird migration. This is especially true for birds that breed in the Northern Hemisphere’s temperate and arctic regions, where there is an abundance of food throughout the brief growing season. Many species must move when food is sparse since they can withstand frigid conditions if there is plenty of it. But intriguing issues still exist.
   
3. Many birds go farther than would be necessary only to locate food and favourable weather, which is a curious reality. Nobody is sure why British swallows don’t travel thousands of miles further to their preferred winter habitat in South Africa’s Cape Province,despite the fact that they could certainly make it through the winter in equatorial Africa. The huge migrations performed by shorebirds that breed close to the poles and arctic terns that hunt on mudflats are still unresolved. In general, migrating species spend their winters farther south the further north they breed. This requires an annual round trip of 25,000 kilometres for arctic terns. All of these individuals, however, fly over other regions of what appears to be ideal habitat spanning two hemispheres en route to their eventual destination in remote southern latitudes. Whilst we may not entirely comprehend the reasons why birds visit certain locations, we can nevertheless be in awe of their accomplishments.
   
4. One of the biggest mysteries is how young birds, who don’t have parental supervision, can find the typical wintering locations.Fewer people travel with young children, and occasionally kids don’t even know what their parents seem like. The cuckoo, which lays its eggs in the nest of another species and never sees its young again, is a well-known example. It is incredible to think that after being nurtured by its host species, the young cuckoo migrates to its original tropical wintering habitats before returning alone to northern Europe the next season to seek for a mate among its kind. The logical conclusion is that it receives from its parents an innate ability to navigate and find its way, as well as a mental image of another cuckoo. However, no one has the foggiest notion how this is even conceivable.
   
5. There is growing proof that birds utilise the sun and stars’ positions as compass directions. Additionally, they appear to be able to sense the earth’s magnetic field, which is possibly because their brains contain tiny magnetite crystals. However, accurate navigation also necessitates a sense of place and time, particularly when being lost. Birds can still quickly return to their nesting locations even after travelling thousands of kilometres over an alien terrain, according to experiments. Such extraordinary abilities are the result of the computation of a number of complex stimuli, such as an innate map of the night sky and the pull of the earth’s magnetic field. Unknown is how the birds employ their “instruments,” but one thing is certain: their sensory awareness of the environment is superior to ours. The majority of tiny birds migrate at night and follow the position of the setting sun. Nevertheless, in addition to witnessing the sun set, they also appear to see the plane of polarised light that it produces, which serves to calibrate their compass. Other advantages of nighttime travel exist. Predators who hunt during the daylight hours are avoided, and there is less of the probability of being dehydrated from extended flight under hot, sunny sky. Additionally, the air is often calmer and cooler at night, which is perfect for stable, long-distance flight.
   
6. All journeys, however, carry a significant amount of danger, and leaving on time is a skill in itself for arriving safely. This calls for using precise weather forecasts and taking advantage of suitable winds. Birds are skilled at both, and laboratory experiments have revealed that some of them can even detect the slight variation in barometric pressure between the room’s floor and ceiling. Birds frequently respond to weather fluctuations before there is any outward evidence of them. Lapwings, which consume grassland, travel from the Netherlands to the British Isles, France, and Spain as a cold front approaches. The birds might go hungry if the ground freezes. However, they make their way back to Holland before a thaw because of a pressure change that predicted an improvement in the weather.
   
7. The day prior a letter announcing its release, a Welsh Manx shearwater that had been transported to America and freed was found returned in its burrow on Skokholm Island off the coast of Pembrokeshire! On the other hand, every autumn, a few North American birds are carried across the Atlantic by swift westerly tailwinds. They certainly make it to Europe without incident, however there is compelling evidence that some of them return to North America the following spring, having likely spent the winter with European migrants in warm African climates.
