Stashed ideas

Now that spring is in the air, the UK is starting to see its summer visitors arriving. Ospreys are already back <a href="https://www.lrwt.org.uk/rutlandospreys">in their nests </a>, chiffchaffs are singing their song to <a href="https://www.jstor.org/stable/4535548?seq=1">re-establish their territories </a>, and puffins have arrived at their <a href="https://www.wildlifetrusts.org/where_to_see_puffins">breeding sites </a>around the British Isles.

Several centuries ago, people believed that swallows spent the winter asleep at the bottom of ponds and lakes, or <a href="https://www.historytoday.com/archive/natural-histories/great-migration-mystery">even on the Moon </a>- but of course, that was complete nonsense.

We now know that animals migrate to increase their survival – and that of their offspring. It also helps in their quest to find food, a mate or to avoid predators.

Although we tend to think of migration as birds flying from one country to another, there are actually <a href="https://www.nationalgeographic.org/article/natures-most-impressive-animal-migrations/">many animals who migrate </a>. Wildebeest, for example, undertake a <a href="https://www.journals.uchicago.edu/doi/abs/10.1086/597229">circular migration </a>, roaming the African plains in huge numbers during the dry season in search of fresh grass. And <a href="http://repositorio.furg.br/handle/1/3452">humpback whales </a>migrate to warmer waters to raise their offspring.

However, it is birds who are the record breakers when it comes to travel.

The <a href="https://www.guinnessworldrecords.com/world-records/86385-longest-non-stop-migration-by-a-bird">bar-tailed godwit </a>has the longest recorded non-stop migration, with one individual spending almost ten days travelling from Alaska to New Zealand without a break – that’s a huge journey of around 12,200km (7,580 miles).

But the <a href="https://www.youtube.com/watch?v=bte7MCSBZvo">Arctic tern </a>is the true champion, making a round trip of 35,000km (22,000 miles) from the Arctic to the Antarctic and back again each year.

Migration is a costly business – birds need to carry enough fat reserves to power their flight and sustain themselves over the duration of their journey. Getting lost could have disastrous consequences, so birds have developed incredible navigation skills to help them fly the shortest and safest routes.

Some species have an innate, inherited ability to migrate, which allows them to move to areas independently to enhance their survival.

The cuckoo, for example, is not raised by its parents as cuckoo mothers lay their eggs in nests belonging to birds of a completely different species. Yet, a young cuckoo is able to travel alone, from Europe to Africa, and back again, by using an inherited <a href="https://news.ku.dk/all_news/2020/06/cuckoo-chicks-have-an-innate-gps/#:%7E:text=By%20moving%20young%20cuckoos%201800,broader%20understanding%20of%20bird%20migration.">“internal GPS” </a>.

But some species, like the Caspian tern – which undertakes a long-distance migration from its breeding home in northern Europe to its wintering location in Africa – have very little inherited basis to their migratory habits. In most cases, they are taught by their parents, also known as “cultural inheritance” or social learning.

Along the journey, he also shows them suitable stopover sites for refuelling with fish and crustaceans.

But, whether inherited genetically or socially, birds <a href="https://www.nationalgeographic.org/media/how-do-birds-navigate/">use a variety </a>of natural cues, such as the shape of coastlines or the position of the Sun or stars –- or olfactory cues like the smell of their nest – to help them navigate their way around the globe.

Some birds, such as homing pigeons, even <a href="https://www.nature.com/articles/news041122-7">use a magnetic map </a>to align themselves with the Earth’s magnetic field as they travel.

Our knowledge of bird migration has increased dramatically since the development of biologgers, tiny data-logging devices that are attached to the birds. These allow us to track an individual’s location, speed, stopover sites and the timing of their migration.

These migrating cuckoos are expected back to their breeding grounds in the UK very soon.

And they are not alone. Many birds undertake long distance migrations to the UK for the summer breeding season. For example, the <a href="https://www.rspb.org.uk/birds-and-wildlife/natures-home-magazine/birds-and-wildlife-articles/migration/migratory-bird-stories/wheatear-migration/">wheatear </a>also winters in Central Africa, but is back in the UK much earlier, from late February to mid August, whereas the <a href="https://hawkandowltrust.org/about-birds-of-prey/hobby">hobby </a>- a predator of dragonflies - winters in South Africa and is in the UK from late April to October.

This enables them to take advantage of the longer hours of daylight and abundance of food, such as insects, during the UK’s summer months.
