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 Sometimes called "Africa's feathered locust", the red-billed quelea is considered a serious agricultural pest in Sub-Saharan Africa. In particular, they eat wheat in the dry season, rice in the early rainy season, and sorghum/millet in the rainy season. An individual red-billed quelea eats around of grain in a day, hence a flock of 2 million individuals—not an unusual size—can consume of grain in a day, or in a month. Their wide range, enormous population and fecundity make control difficult. Traditional methods to protect crops are mainly used in subsistence farming. When the crop is vulnerable, people go into the fields,
