Eurypygiformes

Eurypygiformes  is an order formed by the kagus, comprising two species in the family Rhynochetidae endemic to New Caledonia, and the sunbittern (Eurypyga helias) from the tropical regions of the Americas.  Its closest relatives appear to be the tropicbirds of the tropical Atlantic, Indian, and Pacific oceans."Whole-genome analyses resolve early branches in the tree of life of modern birds"
