Irregular scarer keeps em off guard

CROWS and other crop-threatening birds can become wise to birdscarer devices which go off at regular intervals.

To help catch them off guard, Essex-based Michael Williams Engineering has developed its Bangalore 2000 bird scarer, which can be programmed to go off over random half hour periods during 24 hours.

Using a timer instead of light sensors, the device can be set to switch itself off at night to avoid keeping the neighbour awake.

Powered by a small bottle of propane gas and 12V car battery, the bird scarer weighs 8kg and features a carrying handle for easier transport around the farm. Price is £247 (01799-524642).
