To answer such questions, a network of volunteer specialists has been set up. Over a period of twelve years the results in terms of figures allow us to shed light on a number of questions. The biggest amount of migrants were contained in just 15% of the flocks, and quickly sur-passed in non-consecutive days. The result in terms of hunting bag is inversely proportional to the quantity of birds that compose the flocks. Number of birds shot is not proportional to the number of birds detected, but depends on the quantity of small flocks. It is less than 1% of the birds bag census. The migration observed in the department has not diminished since 1987.
