Larsen trap
Bird trapping device
Bird trapping device

A Larsen trap is a device used to live trap wildbirds. It is used in avian predator control programs, and in scientific research.
It is essentially a cage with two (or more) compartments. A previously caught magpie or crow is kept in the decoy compartment, and this attracts territory holders who see the decoy as an intruder.
Use in the United Kingdom

The Larsen trap is legal to use in the United Kingdom under general licence. It is also used to trap magpies by those concerned for the well-being of nesting song-birds.
The decoy bird must be properly cared for according to local regulations.
The law in Scotland permits their use without any training in how to handle and kill birds humanely. Legally set traps are often vandalised.
