The Accipitriformes are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons.
Incertae sedis or problematica is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by incertae familiae, incerti subordinis, incerti ordinis and similar terms.

The shy albatross, also known as shy mollymawk,, is a medium-sized albatross that breeds on three remote islands off the coast of Tasmania, Australia, in the southern Indian Ocean. Its lifespan is about 60 years, and it has been seen as far afield as South Africa and the Pacific coast of the United States. As of June 2020, the species is listed as "Endangered" in Australia; there are thought to be 15,000 pairs of shy albatross left. It is Australia's only endemic albatross.

The Urrao antpitta, also known as Fenwick's antpitta, is a highly threatened species of bird found in the understory of cloud forest in the Andean highlands of Colombia. The first published description used the scientific name Grallaria fenwickorum ; shortly afterward, a second description using the name Grallaria urraoensis was published. The editors of the latter recognized that the name likely was a junior synonym, but others have questioned the validity of the first description, and various authorities, including the International Ornithological Congress, have adopted G. urraoensis. Antioquia antpitta has been suggested as an English-language name compromise.
The Sucre antpitta is a species of bird placed in the family Grallariidae.
Accipitrimorphae is a clade of birds of prey that include the orders Cathartiformes and Accipitriformes. However, this group might be a junior synonym of Accipitriformes. The DNA-based proposal and the NACC and IOC classifications include the New World vultures in the Accipitriformes, but the SACC classifies the New World vultures as a separate order, the Cathartiformes which has been adopted here. The placement of the New World vultures has been unclear since the early 1990s. The reason for this is the controversial systematic history of the New World vultures as they were assumed to be more related to Ciconiidae after Sibley and Ahlquist work on their DNA-DNA hybridization studies conducted in the late 1970s and throughout the 1980s. The stork-vulture relationship has seemed to not be supported. Regardless of whether to use Accipitrimorphae or Accipitriformes, these birds belong to the clade Telluraves.

The ochre-backed woodpecker is a bird in the family Picidae that occurs over a large area of eastern Brazil. It was previously always considered as a subspecies of the blond-crested woodpecker, but the authors of a molecular phylogenetic study published in 2015 argued that it should be treated as a separate species. This recommendation was accepted by the International Ornithologists' Union, the online edition of the Handbook of the Birds of the World, and the South American Classification Committee of the American Ornithological Society.
