Red-Billed Quelea

Red-billed Quelea are small birds and average-sized weaver-finches. They grow to 11–13 cm (4.3-5.1 in) long and attain a weight of 15 to 20 g (0.5-0.7 oz). During the breeding stage, the adult male is distinguished by his more colorful plumage and red bill. Breeding plumage in male queleas is unusually variable: comprising a facial mask which ranges from black to white in color, and breast and crown plumage which varies from yellowish to bright red. For the rest of the year both males and fledged non-breeding birds have plumage that resembles that of the adult female, which is overall a cryptic beige and cream coloration. The female's bill is yellow during breeding, and red during the non-breeding season.
