Genus Eurypyga

Sunbittern - The sunbittern is usually placed in the Gruiformes, but this was always considered preliminary. In some aspects of its morphology the Sunbittern is close to the herons and their relatives , but this appears to be convergent evolution due to similar lifestyles. Altogether, the two species seem to form a minor Gondwanan lineage which possibly also includes the extinct adzebills and/or the mesites, and is of unclear relation to the Gruiformes proper. Notably, the Kagu and mesites also have powder down.
