India is primarily an agricultural country, and nearly three-quarters of its population depends directly on agriculture for a living. Therefore, agricultural development is intimately connected with the joy and happiness of the people in this country. Total grain production in India could be around 106 million tonnes per year, with a safe five percent increase if bird damage could be avoided. Numerous efforts are made to eliminate this loss, but they are never completely successful.
The first attempt, still used in most parts of our country, was the use of a sling, which has its own drawbacks and limitations, the main one being the unsatisfactory short range it covers. Another method widely practised is to hang a dead bird or to make human figures in the field. The fact that birds are afraid of irritating noises led to the development of many bird scaring devices, which used sounds of various frequencies and a few that sounded like predatory bird voices. These have been found to be successful only for a very short period of time before birds get habituated to them. Plastic nettings stand as an alternative and reliable solution, but they are too costly for a poor country like ours. The use of plastic and paper bags is also in practice, but they too are costly and prove to be detrimental for the growth of crops. This project deals with the fabrication of some simple, but reliable, bird scaring devices.
