MIGRATION: A FLIGHT FOR SURVIVAL he small, seemingly shy Common Quail Coturnix coturnix prefers to stay hidden amongst the rough grasses of farmland as it forages with its long, sharp claws for insects and seeds. Birdwatchers have a much better chance of hearing their characteristic call than seeing them. Their secretive behaviour is for their own good, since unfortunately when they do encounter humans it is often at their peril. This bird’s small and stocky build gives no allusion to the impressive flying feats this species is capable of. These birds habitually avoid flying: if disturbed, they prefer to either run away or ‘freeze’, hoping to go unnoticed. However, this changes in a spectacular fashion when, using their disproportionately long and powerful wings, they take to the skies to migrate between their breeding grounds in northern Europe and wintering grounds in the Sahel belt of sub-Saharan Africa. This makes them the only species of their order (which includes pheasants, partridges and grouse) which migrate. Interestingly, not all Common Quails migrate - the tendency to do so is determined genetically. Within a population, some individuals will perform long migrations, some may only migrate to the southern Mediterranean, and others will not migrate at all. The proportion of quails that migrate is declining and there are two suggestions as to why. Firstly, recurring droughts since the 1970s have disrupted wintering grounds, making individuals that migrate only a short distance (or not at all) more likely to survive. The second theory is that by introducing non-migratory Japanese Quail Coturnix japonica into populations to replenish game stock, the gene pool is being flooded with sedentary genes. The efforts of those that do migrate along the Eastern T COMMON QUAIL FACT FILE WINGSPAN: 32-35 CM TOP SPEED: 60 KM/H THREATS: TRAPPING, HABITAT LOSS APR-JUN 2019 • BIRDLIFE Not all quails migrate – but those that do can travel astonishing distances. Taking off from the Sahel belt of Sub-saharan Africa, they use their unusually long wings to follow the Nile before crossing the Mediterranean Sea and arriving in Europe. COMMON QUAIL MIGRATION ROUTE route are all too often wasted after completing their epic flight across the Mediterranean. Having journeyed across the sea they fly low, heading for a place to rest, but instead find themselves caught up in vast nets, particularly in Egypt. Historically, quails have been an important food source to Egyptians and the consumption of their meat, though limited by quotas, is legal. However, with advances in hunting methods over the last century, the odds have become increasingly stacked against them. Electronic devices placed under nets play recordings of quail song to lure massive numbers towards the traps. Additionally, lack of policing means that regulations on net size, spacing and time of year are ignored – including trapping in springtime, which is illegal. These practices, along with the poor enforcement of catch restrictions, means quail trapping is taking place at an unsustainable, commercial scale. On top of this, it’s not just qthe uails that get caught in the nets. The trapped quails often entice predatory birds such as Merlin Falco columbarius and Eurasian Sparrowhawks Accipiter nisus towards what looks like an easy meal. Nature Conservation Egypt (NCE, BirdLife Partner) has been working with the government to simplify the nation’s often complex anti-poaching laws, and to get them properly enforced on the ground – with emphasis on preventing the use of electronic calling devices. Tourism is a principal source of income for Egypt and NCE works with the industry to ensure its practices are not environmentally damaging. By introducing communities to birdwatching, for example, it demonstrates how nature can generate income and boost the local economy. More importantly, the locals can develop an appreciation and interest in Egypt’s birdlife that goes far beyond their trapping and consumption. An Egyptian hunter brings home a couple of freshly caught quail for dinner. It’s how he feeds his family, a tradition passed through countless generations. But consider nets spanning hundreds of kilometres, trapping tens of millions of birds each year - this is no longer mere subsistence, but an industrial-scale problem. Let’s not allow this to become the third and final reason for Common Quail to cease migrating. 27
