The kagu or cagou (Rhynochetos jubatus) is a crested, long-legged, and bluish-grey bird endemic to the dense mountain forests of New Caledonia. It is the only surviving member of the genus Rhynochetos and the family Rhynochetidae , [ 3 ] although a second species has been described from the fossil record.
While the kagu is the only living species in the family Rhynochetidae, a larger species, the lowland kagu (Rhynochetos orarius), has been described from late Holocene subfossil remains. The body measurements of this species were 15% greater than Rhynochetos jubatus, with no overlap in measurements except those of the wings.
Rhynochetos jubatus is the only extant species of this genus and of the family Rhynochetidae. It is closely related to birds of the tropical Atlantic, Pacific and Indian oceans with its closest living relative being the sunbittern (Eurypyga helias). [3]
Sunbittern, kagu, and mesites all group within Metaves but all the other lineages of "Gruiformes" group either with a collection of waterbirds or landbirds within Coronaves. This division has been upheld by the combined analysis of as many as 30 independent loci (Ericson et al. 2006, Hackett et al. 2008), but is dependent on the inclusion of ...
Notably, the kagu and mesites also have powder down. An indeterminate fossil eurypygid has been documented from the Green River Formation of Wyoming, USA. This specimen, known from a full skeleton, is the oldest and only known fossil of the group, and suggests that eurypygids had a much more northernly range in the past.
Eurypygimorphae or Phaethontimorphae is a clade of birds that contains the orders Phaethontiformes (tropicbirds) and Eurypygiformes (kagu and sunbittern) recovered by genome analysis. [2] The relationship was first identified in 2013 based on their nuclear genes. [ 3 ]

If it is to be included in the lead as an alternative name then the lead should read "The Kagu, or Cagou, Rhynochetos jubatus, is a crested," or "The Kagu, (French: Cagou), Rhynochetos jubatus, is a crested," or more accurately, "The Kagu, (French: Kagou huppé), Rhynochetos jubatus, is a crested," which is the formal named used for the species ...
