The white-rumped tanager (Cypsnagra hirundinacea) is a South American bird in the tanager family Thraupidae. It is the only member of the genus Cypsnagra.
The length is 16 cm with a weight of 25-34 g. They occur mostly in Brazil, also in Paraguay, Bolivia and Suriname at an elevation of 700–1000 m. They inhabit grasslands with few trees. In Brazil they are found in territorial groups of three to six individuals. They eat insects on the ground in the grass or catch them in flight (sallying). Their diet mostly consists of beetles, crickets and grasshoppers but they occasionally eat fruit. The cup shaped nests are placed only 1–2 metres off the ground and are made of woven grasses. The clutch is 3-4 blue eggs which are speckled around the large end with brown or black spots. Helpers born the previous season help mating pair tend the nest and nestlings.
