Sometimes called ‘feathered locusts’, queleas are pests across eastern and southern Africa. A quelea eats 10g of grain daily. Not a huge amount, but flocks can number two million and collectively consume 20 tonnes of grain in 24 hours. The UN's Food and Agricultural Organisation estimates that £41m worth of crops are lost to the birds annually. The latest quelea invasion in Kisumu, amounting to ten million birds, has already decimated 300 acres of rice fields. Another 2,000 acres are still at risk during the harvest season. Worse hit is Narok county where the birds invaded wheat farms, destroying 40% of the harvest. The prolonged drought in the Horn of Africa has meant fewer seeds from wild grasses, a primary source of food for queleas. Kenyan scientists suggest this may be behind the invasion of cultivated land as the birds look for alternatives.
