The Okarito brown kiwi, Apteryx rowi, (also known as the Rowi) is a member of the kiwi family (Apterygidae). The species is part of the brown kiwi complex, and is morphologically very similar to other members of that complex. It is found in a restricted area of the Okarito forest on the west coast of New Zealand's South Island, and has a population of only 200 birds.

The Serendib scops-owl, Otus thilohoffmanni, is a small, rufous owl (Strigidae) found in lowland rainforests in Sri Lanka. The new species was discovered in February 1995, when Deepal Warakagoda heard unfamiliar owl-like vocalisations, although it was not until January 2001, when Warakagoda saw the bird, that his suspicions were confirmed; other observers had suggested that an arboreal amphibian may have been the source of the noises. The name "Serendib" is an old name for Sri Lanka; the species' scientific name, however, honours conservationist Thilo W. Hoffmann.
The Togian hawk-owl, Ninox burhani, is an owl (Strigidae). The bird is known only from three islands in the Togian group, an archipelago in the Gulf of Tomini off the coast of Sulawesi, Indonesia. The new species was discovered on 25 December 1999. The species' scientific name honours a local conservationist called Burhan.

The Rubeho akalat, Sheppardia aurantiithorax, is a member of the Old World flycatcher family (Muscicapiidae), known from the Eastern Arc of Tanzania. Akalats trapped in 1989 here were assumed to be an isolated population of Iringa akalat which occurs c. 150 km to the south, but further specimens collected in 2000 led to the description of the bird as a new species. The bird's English name relates to its type locality; the scientific name to the ochraceous colour on its throat and upper breast. The species is thought to be fairly common in montane forests within its small range.

The Calayan rail, Gallirallus calayanensis, is a member of the rail family (Rallidae) found only on Calayan Island, one of the Babuyan Islands in the Philippines. It was discovered in 2004 as part of a faunal survey of the Babuyan islands. It is found in limestone forests on the island.

Mees's nightjar, Caprimulgus meesi, is a member of the nightjar family (Caprimulgidae). It is a representative of the large-tailed nightjar complex found on Flores and Sumba, Indonesia. Previously unrecognised as a separate taxon due to its lack of morphological distinctness, Sangster and Rozendaal (2004) described this new species on the basis of its vocalisations, which differ significantly from those of the large-tailed nightjar races resident on other islands in the Lesser Sundas. The species is named after Gerlof Mees, former curator of the Natural History Museum, Leiden.

The sulphur-breasted parakeet, Aratinga pintoi, (a member of the parrot family, Psittacidae) is found along the northern bank of the lower River Amazon in Pára state, Brazil. The species' scientific name honours Oliverio Pinto, a Brazilian ornithologist. This species was discovered as a result of a study of museum specimens of sun parakeet and related species; specimens of this species had been dismissed as immature parakeets of other species, or hybrids.

The Upper Magdalena tapaculo, Scytalopus rodriguezi, (a member of the tapaculo family, Rhinocryptidae) is a restricted-range endemic presently known only from two localities on the eastern slope of the Cordillera Central at the head of the Magdalena valley, Colombia at 2000m or more above sea-level. Its range is believed to be no greater than 170 km2, and its population around 2,200 pairs. It is found in humid forest with dense understorey. The species' scientific name honours José Vicente Rodriguez Mahecha, a Colombian conservationist. The existence of this species was first suspected in 1986, when a tape-recording of the bird's song was made, but political instability in the region prevented a return visit until 2002–2003, when the species' existence was confirmed.

Stiles's tapaculo, Scytalopus stilesi, is the second member of the tapaculo family, Rhinocryptidae, to be newly described in 2005. It has been found at 21 sites in montane forest between 1,420 and 2,130 m altitude in the northern Cordillera Central of the ColombianAndes; although having a restricted range, within this limited area it is a common understorey bird. The species was originally observed in the 1990s, but when Niels Krabbe examined recordings of their songs, his suspicions arose that they were a new species – Stiles's tapaculo's song is considerably faster and lower-pitched than that of the closely related Ecuadorian tapaculoS. robbinsi. The species is named in honour of F. Gary Stiles, an ornithologist heavily involved in research on Neotropical birds during the 1980s & 1990s.
