This study was conducted during the 1997-98 rabi season on the Students' Research Farm, Rajendranagar, Hyderabad (Lat 17o 19' N; long 78o 23'E; altitude 543 m above MSL), Andhra Pradesh. The rose ringed parakeets (Psittacula krameri), blossom-headed parakeets (Psittacula cyanocephala), and house crows (Corvus splendens) were observed to attack the unprojected maize crop. The unprotected maize field suffered maximum damager (81%) compared with the protected field. The results of this study reveal that with protection by bird scarers a yield of 1600 kg/ha maize was obtained in the protected maize field as compared to 300 kg/ha only in the unprotected field. There was a loss of 1300 kg/ha in the total yield. The cost:benefit ratio was Rs. 1:3.
