Millions of migratory birds might die as a result of illegal glue-filled traps in Spain.
Running the gauntlet
The long migration to warmer areas in the winter is an arduous and testing task for many birds. Yet for the millions of birds heading to Spain this week, the most dangerous part of the journey may, in fact, be their arrival at the final destination.
Illegal traps, known as parany traps, are being widely used by Spanish hunters. The method involves placing glue-covered twigs and spikes in thickets of trees and it is estimated that these traps may catch up to four million migrating birds.
Migratory bird species flying south to the warm Mediterranean climes, including song thrushes and mistle thrushes, will be at risk from hundreds, if not thousands, of parany traps set in Castellón, eastern Spain, and its neighbouring areas.
Trapping for tapas
While thrushes were once an important source of food in eastern Spain’s countryside region, the majority of the illegally trapped birds are now destined for Spanish bars, where they will be served as tapas. However, the local people state that this is a part of their cultural heritage which dates back to Roman times, and that the long-standing tradition should be allowed to continue: “There are pictures of parany traps in the mosaics of Pompeii,” said Miguel Angel Bayarri of the trappers’ Apaval association.
Although it is not illegal to hunt song and mistle thrushes, nor their cousins the redwing, it is illegal to use parany traps to do so.
Using birdsong recordings, birds are lured into thickets where their wings become glued together, preventing them from flying. Campaigners say that such a method contravenes European wildlife laws.
Despite thrushes being the primary target, it is thought that up to two of every five birds that fall into parany traps are actually other migratory species, including robins, blackcaps and black redstarts. Local birds, such as warblers and owls, are also known to fall foul of the sticky traps. Mr Bayarri, however, said that this is only the case if the traps are badly operated, with members of his association only catching thrushes.
Mario Giménez, head of SEO/BirdLife in the eastern region of Valencia, stated that very few parany operators carry out the laborious and time-intensive task of rescuing non-target birds and releasing them: “Even those cleaned up with dissolvent often don’t survive.”
Politicians have previously tried to legalise parany traps in Valencia’s regional parliament, but have been prevented from doing so by Spain’s higher courts. Campaigners are now calling upon the politicians to publicly condemn the traditional hunting practice as a contravention of EU law.
Worrying times ahead
Despite the trappers’ Apaval association calling for members not to set traps this year, the use of this hunting method continues, with at least 340 functioning parany traps having been identified in the last few weeks. A spokesman from Spain’s Association of Environmental Affairs spoke of the scale of the problem: “They are only the first ones discovered so far this year. In previous years we have found some 2,000 traps.”
Hunters caught setting parany traps can be fined up to €200,000 (£170,000), and could end up with a criminal record. However, the hunting appears to be ongoing.
“The hunting continues, it is just not so flagrant,” said Mr Giménez. “We have seen the traps and heard the birdsong recordings that they use. Now when they hear a car, they do at least turn the machine off.”
A general election is to be held on 20 November, and campaigners fear that a change in government could lead to authorities ignoring the severity of the situation and the impact it has on populations of migratory birds: “The People’s party is expected to win, and that is the same party that has tried to legalise this in Valencia,” said Mr Giménez. “We don’t want a new government turning the clock back.”
