The present study was conducted from July to December 2015 and found that the Shendi area, River Nile State, Sudan, Africa, hosts considerable bird diversity with 35 species being observed belonging to 22 families; of which Columbidae, Meropidae and Nectariniidae were the most frequently observed species.

This study was conducted to determine the role of some micro-ecological factors influencing the population dynamics of schistosomiasis intermediate host snails in the water bodies of Khartoum State, Sudan. The results show that the air and water temperature play a significant role in the determination of snail growth, a gradual increase of air and water temperate causing an increase in the snail population growth rate with the peak in summer. Water of high turbidity and high current speed caused a drop in the snail population. Vegetation cover in water bodies showed a significant effect on the snail population, the denser the cover the higher the snail population growth rate.
