Red-billed quelea sound due to the many wing beats. After arriving at the roost or nest site, birds keep moving around and make a lot of noise for about half an hour before settling in. Both males and females call. The male sings in short bursts, starting with some chatter, followed by a warbling "tweedle-toodle-tweedle". The red-billed quelea is mostly found in tropical and subtropical areas with a seasonal semi-arid climate, resulting in dry thornbush grassland, including the Sahel, and its distribution covers most of sub-Saharan Africa. It avoids forests, however, including miombo woodlands and rain forests such as those in central
Red-billed quelea during flooding. It needs shrubs, reeds or trees to nest and roost. Red-billed queleas migrate seasonally over long distances in anticipation of the availability of their main natural food source, seeds of annual grasses. The presence of these grass seeds is the result of the beginning of rains weeks earlier, and the rainfall varies in a seasonal geographic pattern. The temporarily wet areas do not form a single zone that periodically moves back and forth across the entirety of Sub-Saharan Africa, but rather consist of five or six regions, within which the wet areas "move" or "jump".
