Zwanendriften in The Netherlands (Swan Herding). I never knew this practise existed until recently and it is ghastly. Apparently now illegal (since 2013) the swan herders continue to catch swans, cutting their wings so they can no longer fly, tattooing their beaks and return to 'harvest' them ( killed for their feathers, down and meat!) at a later date. This started in the middle ages.....oh gosh!
