I confirm that I was fortunate enough to be offered the opportunity to trial the bird alarm. I was particularly interested in using this in my horse truck which unfortunately suffers an epidemic of bird nesting during the season. The truck is located in a very large implement shed/stable area which is also infested with birds during the nesting season. I installed the device near the truck and then cleared the area affected by nesting. The birds did not return to the truck and I noticed a significant decrease in the number of birds nesting in the shed, particularly in the immediate proximity of the alarm’s location. I believe the alarm is very effective and has great potential to be developed further to operate in larger areas.
