Studies on damage patterns of house crow (Corvus splendens) extended on the randomly selected farm crops, viz. fresh and mature maize cobs, harvested wheat, sunflower and barley, in the morning and afternoon foraging sessions, each three hours duration, February, 2001 till July, 2001, depicted the damaged plants, for freshly sown maize 12.61 plus-minus 2.33 (m); 18.32 plus-minus 2.70(a), mature maize cobs 13.54 plus-minus 3.18 (m); 10.11 plus-minus 1.97 (a); harvested wheat 9.22 plus- minus 2.37 (m); 14.94 plus-minus 1.53 (a), sunflower 14.25 plus-minus 2.60 (m); 17.50 plus-minus 1.58 (m) and 3.58 plus-minus 0.82 (m); 12.61 plus-minus 2.58 (a) on barley. It was evident that most intensively depredated plant in the morning foraging periods was sunflower, whereas in the afternoon, it was maize. It was concluded that appropriate control measures employed judiciously in and around the crow roosts would be beneficial to avert the damage.
