More Bird trap
You cannot legally trap most birds in many states and countries. However, in a survival situation, or to do some basic population control in your yard, light trapping is permissible. Though you may need a permit, and you'll certainly find pre-made traps more effective, you can build your own bird trap with some basic supplies at home or in the wild.
Looking somewhat like an upside down "L," the Ojibwa Bird Pole has been a staple of indigenous hunters in Canada for centuries. Birds perch on a small horizontal branch, which you rig to fall under their weight. They are then caught in a noose positioned underneath before they can fly away.
