Britain's gamebird of choice is more exotic in origin than you might think
The pheasant’s gradual triumph over the sporting imagination belies this striking gamebird’s hotly contested impact on flora and fauna, writes Mark Cocker.
A male common pheasant in full breeding regalia is arguably one of the most colourful sights in all of British birdlife. When two cocks spar in spring, facing up to one another in prolonged tail-twisting jousts, they are nothing less than spectacular. It’s not only their weird, fleshy crimson goggles, imperial purple ear-horns and emerald gourgets, but their exquisite repeat rows of elliptical black tips to all the orange-cinnamon breast feathers and the longitudinal black-and-buff margins to their neck and shoulder plumes.
Male pheasants appear exotic and, in some senses, they are out of place amid the subdued tones of our woodlands. Both parts of the bird’s scientific name, Phasianus colchicus, refer to its true origins, which stretched right across Asia from China to the Caucasus. Yet Europeans acquired their first captive stock at the western edge of the bird’s range, in an area on the eastern shores of the Black Sea with the ancient name of Colchis.
Medieval aristocrats were entranced by the bird’s Asiatic beauty, although few could have anticipated the pheasant’s gradual triumph over the sporting imagination, to the point where it had a central place in shaping the very lands of Europe. The bird was repeatedly introduced and acquired self-sustaining populations from Norway to Bulgaria. It was also taken around the world to North America, Australia, New Zealand and Hawaii. In this country, records of pheasants may go back to Roman times, but certainly date from the Norman period.
Since the late 20th century, pheasant's status as a game bird has grown, partly because of the declines of red and black grouse and grey partridge.
Bizarrely, pheasants barely feature as a subject for study.
Now, it is indubitably the gamebird of choice. Its exalted place has been much enlarged since the late 20th century, partly because of the parallel population declines of our other native sporting birds — red and black grouse and grey partridge. For all the pheasant’s long heritage in these islands, it remains a non-native species, classiied by officialdom on Category C, together with other aliens, such as parakeets and mandarin ducks.
There is also a kind of unofficial sniffiness among birdwatchers. Twitchers almost scrupulously ignore pheasant behaviour and the birds barely feature as a subject for study. Those attitudes were humorously captured by one wag, who once saw a pheasant being washed briefly into the sea as it stood on a rocky Scottish shoreline. ‘This is probably the only known case,’ he wrote, ‘of a pheasant doing something interesting.’
In some ways, he could not have been more wrong. Like the duelling cock birds evoked in my opening scenario, there are now two opposed pheasant camps jousting with one another. At issue is the birds’ present-day abundance. Hand-reared poults, bred in pens, fed from grain hoppers and released in the summer in time for the start of the shooting season in the autumn have become the largest single species’ contribution to our entire avian biomass.
Even placing a figure on the numbers now being liberated has itself become part of the heated pheasant debate. Estimates range between 25 and 60 million, depending on the claimant’s position, however, an authority accepted by most sides has proposed that in 2019, 47 million were released.
Pheasants are largely vegetarian, yet switch to a mixed diet in spring and summer.
A study looking at the impact of pheasant releases upon reptiles has been taken as proof that they are having adverse effects on biodiversity.
Pheasants are largely vegetarian, yet switch to a mixed diet in spring and summer. The exact proportion of animal matter may fluctuate, but not the charge that large numbers of released pheasants are having major local effects on invertebrate populations.
A study in Belgium looking at the impact of pheasant releases upon reptiles — slow worms, lizards and snakes — has been taken as proof that they are having disproportionate and adverse effects on overall biodiversity. The pro-pheasant lobby is reluctant to go so far and prefers to stress the positives in terms of employment and economic stimulus to our rural places.
Another side issue is the grisly matter of road-kill. A minimum estimate for mortality on our roads is 2.8 million pheasants. One consequence is the food bounty that the squashed carcasses provide for foxes. Opponents of pheasants argue that it is the shooting community — ironically, those least sympathetic to old Reynard — that is providing the biggest boost to fox numbers. These animals are then driving fox predation of other beleaguered ground-nesting birds, such as curlews and lapwings.
