Silent birdscarers prove their worth

SALES of silent birdscarers have grown dramatically in recent years as complaints about gas guns have increased, claims an East Anglian supplier.

Sales turnover of silent scarers has increased more than 10-fold in just one year, says Jane Lewis of Peaceful Pyramid Birdscarers, who has joined forces with another East Anglian business, Combat Balloons.

"Its important to make use of alternative methods because birds will get used to any one system after a period of time," says Mrs Lewis. "The two methods we are marketing complement each other, so there is always something to keep birds at bay."

The Peaceful Pyramid uses reflected light as a deterrent and consists of a rotating, reflective pyramid powered by a small electric motor running from a 12v battery. "It deflects light into the air at the reverse angle of the birds approach. The intensity of the reflection confuses the bird by overloading its visual sensory receptors, removing the impulse to land and feed."

The latest units use a light sensor to switch the motor off during darkness. Each unit operates with a fully charged battery for more than 10 weeks without attention.

Two pyramid heads are supplied – one clear-sided, the other with two red sides which are particularly effective against rooks. Tests show the Peaceful Pyramid works across up to 4ha (10 acres).

"The important thing is to put them out when you drill," says Mrs Lewis. "Dont wait for a problem to develop. If theyre there from day one, they will be a complete deterrent."

It doesnt have to be sunny for the scarers to work, she adds. "Birds eyes are very sensitive, so they work in cloudy conditions." But rainsplash and mud need wiping off.

Cost is £103 plus packing, delivery and VAT, with a 14-day money-back guarantee.

Combat Balloons are also available from Mrs Lewis. They offer an alternative bird-scaring system which is also silent, robust and safe.

The balloon is a brightly coloured visual deterrent, and inflates to 1m (3ft) across using helium gas. Once it is launched, circling pigeons assume it is a predator.

The balloon can fly up to 40m (125ft) high, and just one will protect up to 8ha (20 acres), says Mrs Lewis. "There is a bit of work involved as they need topping up with helium every seven to 10 days."

The balloon is made of latex, and the outer cover of rip-stop nylon sail fabric. A long polythene tail provides a visual deterrent in the slightest breeze.

"They can stay afloat in winds of up to Force 4, although they tend to be blown more horizontal in these conditions," says Mrs Lewis. "And if its very wet, they become heavy and fall to the ground. But they relaunch themselves once dry."

Cost is £92 plus delivery and VAT. &#42
