Red-billed quelea parasites found in queleas include "Haemoproteus" and "Plasmodium". The red-billed quelea is caught and eaten in many parts of Africa. Around Lake Chad, three traditional methods are used to catch red-billed queleas. Trappers belonging to the Hadjerai tribe use triangular hand-held nets, which are both selective and efficient. Each team of six trappers caught about twenty thousand birds each night. An estimated five to ten million queleas are trapped near N'Djamena each year, representing a market value of approximately US$37,500–75,000. Between 13 June and 21 August 1994 alone, 1.2 million queleas were caught. Birds were taken from roosts in the
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,
