Red-billed quelea trees during the moonless period each night. The feathers were plucked and the carcasses fried the following morning, dried in the sun, and transported to the city to be sold on the market. The Sara people use standing fishing nets with a very fine mesh, while Masa and Musgum fishermen cast nets over groups of birds. The impact of hunting on the quelea population (about 200 million individuals in the Lake Chad Basin) is deemed insignificant. Woven traps made from star grass ("Cynodon nlemfuensis") are used to catch hundreds of these birds daily in the Kondoa District, Tanzania. Guano is
3D Virtual Creature Evolution (from zero, as not having an influence on fitness, to one, or having maximum influence) to determine the fitness goal. What generations the fitness function applies to can also be set. The environment, or “Terrain”, is then determined. This includes a flat plain, bumpy terrain (in which a hill is generated around creature that constantly inclines as distance is traveled from the creature’s spawning point), water (a low gravity simulator, non-functional), and “spheres” (spheres are generated above creature to catch). Everything in the simulation is viewed from a first person viewpoint. After settings are determined, the first generation is generated
