The trap attracts target birds to feed and is triggered when the bird steps on a perch. The trap then drops the bird via gravity into a quiet, comfortable space until they are ready for live removal and relocation. There is no stress to the bird – no part of the trap makes contact nor does a human touch.
Carrion crow in a trap in Scotland. The cage includes a tub of water and a pheasant carcass, for the benefit of trapped birds. The Larsen trap is legal to use in the United Kingdom under general licence.

Bird control or bird abatement involves the methods to eliminate or deter pest birds from landing, roosting and nesting. Bird control is important because pest birds can create health-related problems through their feces, including histoplasmosis, cryptococcosis, and psittacosis. [1] Bird droppings may also cause damage to property and equipment.
One study found the average rate of injury for birds in mist nets is lower than any other method of studying vertebrates, between 0 and 0.59% while the average mortality rate is between 0 and 0.23%. [1] While rare, it has been suggested (without scientific studies) that larger birds may be more prone to leg injuries and internal bleeding.

Mechanical controls—Should a pest reach an unacceptable level, mechanical methods are the first options. They include simple hand-picking, barriers, traps, vacuuming and tillage to disrupt breeding. Biological controls—Natural biological processes and materials can provide control, with acceptable environmental impact, and often at lower cost.
Bal-chatri (/bɑːl tʃʌθri/) are traps designed to catch birds of prey (raptors). The trap essentially consists of a cage baited inside with a conspicuously visible live rodent or small bird, with a series of monofilament nooses attached to the surface to snare the legs of a free-flying raptor that attempts to take the bait.
