Robin caught in a bow trap ('archetti') in northern Italy
The mechanics of the bow trap, which at first glance looks quite simple, are astonishing and extremely brutal: a small stick and a string keep the bow, which is traditionally made of a hazelnut rod (today mostly wire), under tension. Birds are attracted by rowan berries and are tempted to settle on the horizontally mounted stick. When they touch it, the bow rushes apart. In just a fraction of a second, the birds hang upside down with their legs completely crushed in the noose. This way the birds stay 'fresh' for a long time even in the warm autumn sun and are only dispatched by the bird trapper after hours of agony. Some, however, also die from blood congestion in the head, general cardiovascular failure or simply bleed to death.
Robins make up about 90% of the birds trapped with bow traps. Among the remaining 10 % there are mainly song thrushes, wrens and goldcrest, more rarely brambling and chaffinches, titmice and large birds such as long-eared owls or jays get caught. Occasionally, dormice and hazel mice also die in the traps.
In the subsequent years, cooperation was agreed and took effect for the first time in 1999. Instead of dismantling the traps, we led the officials to the trapping sites, so that they could ambush and catch and convict the poachers red-handed! Each autumn more than 50 poachers were quickly nabbed - the fear of the bird trappers was evident in the number of bow traps found in 2002: There were only 9,500 bow traps left. To date, the number of bow traps has continued to fall drastically. In autumn 2007 we still found 1,320 traps, in 2012 we were able to drop below the "magic" limit of 1,000 for the first time with 963 traps, in 2018 it was only 392, autumn 2019 we collected 224 and so far this year we are yet to find a single one!
Not only the number of traps has changed, but also the "trapping season". Because of the constant danger of being caught, bird trappers today only use the core time of bird migration. The traps no longer stand set for three months in autumn, as they used to, but only from the beginning of October to mid-November!
