The Yellow-Crowned Bishop is a small, energetic weaver that transforms during breeding season into one of the most eye-catching birds in the grasslands. The male’s plumage turns jet black with bright yellow patches on the back, wings, and especially the crown, giving it the look of a feathered fireball. These birds are mostly seen in wet grasslands, marshy areas, and along rivers where reeds and tall grasses grow. Outside of breeding season, males look much like the females — streaky brown and easy to miss. But come summer, they become bold, flashy, and highly territorial, performing bouncy display flights to impress females and warn off rivals. They weave oval-shaped nests suspended in grasses or reeds, usually in colonies. Males build multiple nests to attract females and will mate with several — polygynous and proud. The female does the actual incubation and chick-rearing. Yellow-Crowned Bishops feed mostly on grass seeds, but they also eat insects, especially when feeding young. Though small, they play an important role in the grassland ecosystem by spreading seeds and controlling insect populations.
