The feeding of animals as a friendly gesture is deeply rooted in man. This behaviour has a negative effect on the Street-pigeons which as a consequence suffer from overpopulation. The problem can only be solved by limiting this feeding. The pigeon-feeders are the cause of the pigeon-problem in our cities. The feeders can by their motivation be classified in various groups. Play-feeders and display-feeders can be recognised. They are more easily to be dealt with than the fanatical pigeon-friends who show a strong emotional attachment to these birds. The pigeon-problem can be overcome if this stubborn group can be taught to change his behaviour. Such a solution would be highly rewarding as great sums of money are spent to remove damages caused by the pigeons to buildings and works of art.
将喂食动物作为一种友好的举动在人类中根深蒂固。这种行为对城市鸽子产生了负面影响，导致其数量过多。这个问题只能通过限制这种喂食行为来解决。鸽子喂食者是我们城市鸽子问题的根源。根据动机，喂食者可分为不同群体。可以识别出玩耍喂食者和展示喂食者。与那些对这些鸟类表现出强烈情感依恋的狂热鸽子爱好者相比，他们更容易应对。如果能让这个顽固的群体改变行为，鸽子问题就能得到解决。这样的解决方案将带来巨大回报，因为为消除鸽子对建筑物和艺术品造成的损害花费了大量资金。
