ProAves personnel identified that many children were carrying slingshots with the sole purpose of hunting birds. To deal with this problem Pro-Aves launched a Slingshot Amnesty campaign and as a result some 400 slingshots were handed in by children across Colombia. The slingshots handed in have been displayed in the ProAves head office in Bogotá, the capital of Colombia to serve as an example to the hundreds of children who wish to become friends of birds and generate publicity to attract organisations and schools to help prohibiting the use of these weapons.
