Standing on a green mound is a shield and two crossed spears. The green symbolizes Uganda's lush, green vegetation. Supporting the shield are the Uganda Kob (Adenota kob Thomasi), symbolizing abundance of wildlife; and the Crested Crane (Regulorum gibbericeps), Uganda's national bird. The shield and spears symbolize our readiness to defend our motherland against all enemies. Across the top of the shield are the waves of Lake Victoria, the second largest fresh water lake on earth. In the centre of the shield is the sun, representing Uganda's glorious sunny days. At the bottom of the shield is the traditional African drum, used for dancing, ceremonial rituals, and for summoning the people to rally. Coffee and cotton, Uganda's main cash crops, are displayed on the green mound; together with the River Nile, the world's longest river; which starts its 8 000 km (5 000 mile) journey in Uganda. The Uganda motto is "For God and My Country".
