Lasers prove to be efficient pigeon deterrent in farm trial
It may sound like something from a 1960s B-film, but a project in North Yorkshire that uses lasers to deter pigeons is proving remarkably successful.
Gavin Milson, project technical assistant at Stockbridge Technology Centre, Cranfield University and high-tech GPS company Manterra reckon that using laser-based bird deterrents could be a cost-effective answer to dealing with the feathered fiends.
The equipment emits a strobing laser – akin to what you might find at a disco – which serves to scare off troublesome birds.
In a Tru-Nject project – a high-tech study designed to investigate soil mapping and fertiliser application – had been set up to in late July this year, 165,000 pointed cabbage were transplanted at a North Yorkshire farm. Normally the crop would be netted after transplanting, but the project team used a Dutch Agrilaser Autonomic laser, powered by a solar panel and deep-cycle gel battery.
Mr Milson is delighted with the outcome
“This novel piece of technology appears to have effectively protected the cabbages.”
“Its potential for bird control in field vegetables has generated significant interest and is threatening to emerge as a major, albeit unexpected, output from the project.”
“Whilst light bird damage has been noted on selected plants in some isolated areas of the crop, complete loss of any individual plant to birds has not.”
“Indeed, the vast majority of plants have received no unwanted attention from pigeons at all.”
The Tru-Nject team are now discussing plans to fully test the system in an oilseed rape crop later this year, comparing laser-protected crops to unprotected control crops. It is hoped that this will provide even stronger evidence that the Agrilaser can function as a stand-alone option to manage bird damage in field crops.
