Red-billed quelea including annual grasses of the genera "Echinochloa", "Panicum", "Setaria", "Sorghum", "Tetrapogon" and "Urochloa". One survey at Lake Chad showed that two thirds of the seeds eaten belonged to only three species: African wild rice ("Oryza barthii"), "Sorghum purpureosericeum" and jungle rice ("Echinochloa colona"). When the supply of these seeds runs out, seeds of cereals such as barley ("Hordeum disticum"), teff ("Eragrostis tef"), sorghum ("Sorghum bicolor"), manna ("Setaria italica"), millet ("Panicum miliaceum"), rice ("Oryza sativa"), wheat ("Triticum"), oats ("Avena aestiva"), as well as buckwheat ("Phagopyrum esculentum") and sunflower ("Helianthus annuus") are eaten on a large scale. Red-billed queleas have also been
