Elgeeco clam action Larsen Trap Extra Catching Cages can be set in numerous configurations around or on top of a decoy bird cage to provide additional and alternative catching compartments.

The superior effectiveness of these catch traps is due to their open top and sides, meaning that magpies and crows are more likely to enter because they think they can hop on and off the perch and leave through the open top or the opposite open side.

These cages can also be deployed separately in different locations with more chance of catching individual and decoy birds.  See also Magpie and Crow Trap.

Larsen Trap Extra Catching Cages are considerably more portable and less likely to be seen and stolen than the conventional Larsen traps.
