Collection on Quelea Research. Special Collections, USDA National Agricultural Library.
Quelea is the common name for an East African weaverbird (Quelea quelea). Less than 5 inches (13 cm) long and weighing slightly more than one-half ounce (1.3 grams), the tiny birds are found throughout sub-Saharan Africa in areas receiving less than 30 inches (76 cm) of annual rainfall. With the spread of grain farming and irrigation, the birds have extended their natural habitats, generally picking new breeding grounds every year. Highly mobile, they often descend in a locust-like manner upon fields, and in flight may indeed be mistaken for a swarm of locusts. Queleas are often found in concentrations of more than a million birds; such a flock can destroy up to 60 tons of grain in a single day, consuming half and knocking the rest to the ground.
