Abstract: 

Many parrot species are considered agricultural pests, although objective evaluations of their impact are rare. Burrowing Parrots (Cyanoliseus patagonus) are among these species. Their most numerous breeding colony, with 35.000 breeding pairs, is found at El Cóndor, North-eastern Patagonia, Argentina, and has been described as the largest parrot colony worldwide. In the surrounding area, farmers often complain about damage to their crops caused by this important parrot population. However, until now this issue has not been objectively evaluated. As a first step, this study aimed to evaluate the perception of the damage by local farmers. A total of 120 farmers from North-eastern Patagonia participated in questionnaires carried out during 2004 and 2005. Contrary to our expectations, only one third of the farmers stated that they had suffered any damage to crops from birds in general. Of these, about half the cases stated that the damage had reduced production, while the other half evaluated the damage economically irrelevant. Although some crops like corn, barley, sunflowers, wheat, millet, almonds and apples were affected by Burrowing Parrots between December and March, the farmers declared less damage than expected from the frequent compensation claims of the farmers of North-eastern Patagonia. In total, only 16% of the participants declared damage by Burrowing Parrots, which they considered economically relevant. It should be highlighted that the major part of the damage was noted in small farms. A total of 12% of the farmers stated that they used control measures. An important finding was that lethal control measures were ineffective, as the economical investment was greater than the damage caused by the birds. Farmers that used non-lethal control measures obtained, according to their own perception, economically viable results. These methods may therefore be used as effective control measures. However, the farmers of this region have little knowledge of existing techniques that may be effective in preventing bird flocks from feeding in their fields.
