Abstract

For a bird shooting system, the birds are placed in boxes whose opening is controlled. One or more of these are raised vertically, it being possible to open the boxes during the operation. They can be guided up a mast (2) by means of ropes (12) clear of and parallel to it, being lifted by a further rope (14') reeved over a pulley at the top of the mast and back to a winch at the base, driven by a motor via a reduction gear. There can be a cover on the box (1) on the opposite side to the mast, released by a solenoid-operated trigger.
