turkey traps for other birds

I recently found some old pictures of a turkey trap, its simply a cage made of stacked sticks ,at one end a ditch or trench is dug and bait is placed along the trench and in the cage , the bird can walk into the cage by ducking under ,and apparently can't find its way out ,  i wasn't sure if it would actually work as a trap so i tried it on a pigeon

I took a shopping basket and dug the trench and added sunflower seeds as bait

the trap worked perfectly ,for some reason the birds can get in but cant seem to find their way out again .

the last picture is the traditional way to do the turkey trap
so in a survival situation this trap would be well worth trying .
