The toll is estimated on the basis of field data from BirdLife’s ongoing field monitoring of trapping activity with mist nets and limesticks, part of a systematic surveillance programme. This latest estimate – 866,905 birds- represents the number of birds killed between Thursday 1st September and Sunday 9th October 2011. The trappers are after Blackcaps and other songbirds, which will end up as illegal, and expensive, ambelopoulia delicacies served up in law-breaking restaurants, allowing the trappers to make huge profits. The first estimate for the autumn 2011 season, posted on September 12th , was for almost 90,000 birds, but trapping has gained pace since then. The estimate will be updated every Monday until the end of October.
