<p>The invention includes a construction of several assembled elements which channel the passage of birds that cause a disturbance to a large chamber. Said elements include: rows of tilted window panes (1) (40m2 or 120m2); shutters (2) placed along said window panes (1); curtains made of hard rubber (12) and of plastic cloth (13), and ventilators (25) which provide a current of air. The birds held in the large chamber are separated by a metal grid (28), the small birds being kept apart. The invention can be used in airfields and in fields under cultivation (in those cases where the birds eat the crops en masse). Other applications include biological and ornithological research, said invention being however in no way designed for hunting purposes.</p> |
