| Abstract | ||||
| Field trials were carried out under different habitats at Assiut Governorate to assess the damage caused by house sparrow birds in some field crops during the year of 2003 and 2004. Two experiments were carried out on the wheat crop as well as on long and short variety of sorghum crop; the first one in old lands the other in newly reclaimed land. The damage percentage was recorded in different growth stages till crop harvesting. The obtained results indicated that there were significant differences between the damage which caused by house sparrow in old land (1.6 & 1.23%) and that happened in newly reclaimed land (0.40 & 0.34%) during 2003 & 2004. The Sparrows attacked the eaten crop starting from formation milky stage with highest damage percent in dough stage during the two seasons (2003 & 2004). The damage percentage was not recorded in appearance of ears stage and flowers that prevent the sparrow from attacked the ears during completion mature of seeds. Concerning different habitat, the results revealed that there were highly significant differences between damage percentage in sorghum crop for both varieties (Giza 15 & Dorado) in old land, the value being 14.26 and 12.94% during 2003 and 2004, respectively. While in the newly reclaimed land, the values of damage percentage were 5.54 and 2.32% during 2003 and 2004, respectively. The highest damage percentage was noticed in the long variety of sorghum (Giza 15) at old land and newly reclaimed land (15.56 & 12.24%), while the damage percentage in short stem variety (Dorado) was 2.24 and 3.02% during 2003 and 2004, respectively. The bird caused damage by attacking the sorghum crop starting from the milky and doughy stages then increased gradually till the harvest time. | ||||
