Just in case anyone doesn't visit the GOS homepage,...
Last Thursday an illegally set net (probably aimed at trapping finches) was found on the Newport Wetland Reserve which resulted in the death of a Reed Bunting (luckily, a number of other birds were released). If you see anything suspicious on the reserve please contact either the CCW reserve manager (Kevin Dupe) on 01633 275813 or the the Police Wildlife Liaison Officer for Newport (Tony Williams) on 01633 244999. There have been suspicious reports of bird trapping elsewhere on the levels in the past, so keep please your eyes open whenever out and about.
Mist-netting of birds to be ringed as part of the BTO Ringing Scheme is undertaken by the Goldcliff Ringing Group on the reserve (though largely on private parts of the site), and at other sites in the county. BTO ringers check their nets at 15-30 minute intervals (depending on conditions) so should be regularly visible and are pretty approachable and happy to answer queries but, if you see anything suspicious, err on the side of caution and contact the numbers above.
According to the RSPB website, last year, they received 64 reports of the illegal taking, possession or sale of wild birds (other than birds of prey) across the UK, these predominately involved finches. There is a market both in the UK and Europe (e.g. Malta) and birds fetch £40+ for the bastards doing the selling. As someone once said,... keep 'em peeled.
