This collapsing bird trap works great in areas where pigeons frequent. It offers a large size/capacity and the ability to fold down only 1" for easy transporting. To collapse, there are no pins to pull or wires to cut, simply push the sides out a little and fold it flat. Pigeons enter the trap at each end through swinging doors and move forward towards the bait.This trap has been built-in feature for optional water/feeder kit. Birds are easily removed through a spring loaded door at the top of the cage.
