Fody breeding plumage are usually colourful with bright red or yellow on the head and sometimes elsewhere. Non-breeding males and females are dull, sparrow-like birds with mostly grey-brown plumage. Fodies are typically found in forest, woodland or scrubland but some also occur in man-made habitats, especially the red fody. Some species feed mainly on seeds while others are largely insectivorous. Fodies build a dome-shaped nest of grass and other plant material. It has a side-opening and it is suspended from a branch or palm leaf. The genus was introduced by the German naturalist Ludwig Reichenbach in 1850. The type species was
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
