The study was evaluate the damages caused in the crops viz., Sunflower, millets and paddy. In the developed bird scarer device, a FM transmitter has been built inside the kit which enables the farmer to use it at the time of relaxation. The solar bird scarer was developed with 12 V battery,5 watt solar panel with IC 440, 22K resistor with remote sensors. The efficiency of the device was tested in maize field and the efficiency ranged from 81.25 ton 84.62 per cent and in sorghum field it ranged from 78.95 to 85.71 per cent. The decibel level of various audios were played through the developed system in the field were 90 to 95 dB and it was found that increasing the decibels to scare more birds. Different audio sounds like explosives, crackers, wolf, lion and some bird predators sounds were played to scare the birds in the field. The more efficient scaring sound is found to be the sound of Hawk, followed by the Eagle and the siren sound. The cost of the developed kit is Rs.4250/- and it can be easily adoptable to utilize the system to deter the bird with low cost of the farming community.
