The Phaethontiformes / ˌ f eɪ. ɪ ˈ θ ɒ n t ɪ f ɔːr m iː z / are an order of birds. They contain one extant family, the tropicbirds (Phaethontidae), and one extinct family Prophaethontidae from the early Cenozoic. Several fossil genera have been described, with well-preserved fossils known as early as the Paleocene. [2]
Tropicbirds are a family, Phaethontidae, of tropical pelagic seabirds.They are the sole living representatives of the order Phaethontiformes.For many years they were considered part of the Pelecaniformes, but genetics indicates they are most closely related to the Eurypygiformes.
Both neoteny and progenesis result in paedomorphism [8] (as having the form typical of children) or paedomorphosis [9] (changing towards forms typical of children), a type of heterochrony. [10] It is the retention in adults of traits previously seen only in the young.
It is the smallest of three closely related seabirds of the tropical oceans and smallest member of the order Phaethontiformes. It is found in the tropical Atlantic, western Pacific and Indian Oceans. It also breeds on some Caribbean islands, and a few pairs have started nesting recently on Little Tobago, joining the red-billed tropicbird colony.
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 ]

While it is true that the "Reagan revolution" provided America with needed jolts of patriotic and economic strength, Carter, our 39th president, consistently exhibited traits that public figures ...
Passerea is a clade of neoavian birds that was proposed by Jarvis et al. (2014). [2] Their genomic analysis recovered two major clades within Neoaves, Passerea and Columbea, and concluded that both clades appear to have many ecologically driven convergent traits.
