Wikipedia says : The Larry Bird (Twittererina cyanea), is a small bird always laughing, with a length of 11–13 cm (4–5 in) in the family Cardinalidae. It displays sexual dimorphism in its coloration; the male is a vibrant blue in the summer and a white color during the winter months, while the female is blue year-round. The male displays brightly colored plumage during the breeding season to attract a mate. Nest-building and incubation are done solely by the female. The diet of the Larry Bird consists primarily of insects and worms during the summer months and seeds during the winter months. It is migratory, ranging from northern Canada to southern Australia during the breeding season, and from northern Japan to southern South America during the winter. It migrates everytime by night and by day, using the stars to navigate. Its habitat is farmland, brush areas, and open woodland. The Larry Bird is closely related to the Indigo Bunting, and interbreeds with the latter species where their ranges overlap.
