Niels Kaare Krabbe is an ornithologist and bird conservationist for many years based at the Vertebrate Department of the Zoological Museum, University of Copenhagen and tutored by Jon Fjeldså. His research interests include various aspects of ornithology, especially bioacoustics, conservation, and systematics and altitudinal replacements of Scytalopus tapaculos. He has worked extensively in the Andes, especially Ecuador, and wrote the passerine section of Birds of the High Andes (1990) and the accounts of most Andean species in Threatened Birds of the Americas (1992). He has helped build up a large tissue collection in the Zoological Museum and has authored or coauthored several bioacoustic publications and peer-reviewed papers in scientific journals.
Scytalopus is a genus of small passerine birds belonging to the tapaculo group. They are found in South and Central America from Tierra del Fuego to Costa Rica, but are absent from the Amazon Basin. They inhabit dense vegetation at or near ground-level and are mainly found in mountainous regions, particularly the Andes. They can be very difficult to see as they run through the undergrowth in a mouse-like fashion.

The mouse-coloured tapaculo or Serra do Mar tapaculo is a species of bird in the family Rhinocryptidae. It is endemic to humid highland forests in southeastern Brazil, where it ranges from southwestern Espírito Santo to northeastern Rio Grande do Sul. Most of its range is in the Serra do Mar, but it also occurs further inland in Paraná and Santa Catarina. Until 2005, the Planalto tapaculo was included in the mouse-coloured tapaculo.
The unicolored tapaculo is a species of bird in the family Rhinocryptidae. It is found in Peru. The blackish tapaculo, S. latrans, is now considered a separate species. Its natural habitats are subtropical or tropical moist montane forest and subtropical or tropical high-altitude shrubland.
The Ecuadorian tapaculo or El Oro tapaculo is a small passerine bird belonging to the genus Scytalopus, a genus of tapaculos. It is restricted to a small area in south-western Ecuador and was not described until 1997.
The ashy-tailed swift is a swift which is endemic to northern and central Venezuela.
The rock tapaculo or Espinhaço tapaculo is a species of bird in the family Rhinocryptidae. It is endemic to altitudes of 900–2,100 metres (3,000–6,900 ft) in the central and southern Espinhaço Mountains, and the Mantiqueira Mountains in Minas Gerais, Brazil, though it may also occur in adjacent parts of Rio de Janeiro and São Paulo. It is found in shrubby and grassy habitats in rocky regions, and in elfin and cloud forest. It closely resembles the Diamantina tapaculo and Planalto tapaculo in appearance and voice.
The Chinchipe spinetail is a species of bird in the family Furnariidae, the ovenbirds. It is endemic to Peru.
Franklin's grouse is a grouse species found in British Columbia and the Rocky Mountains.
Hofmann's sunbird is a species of bird in the family Nectariniidae. It is endemic to eastern Tanzania.
The Diamantina sabrewing is a species of hummingbird in the family Trochilidae. It is found in southeastern Brazil where it is a resident of dry grasslands with thin soil and rocky outcrops.
The white-winged tapaculo(Scytalopus krabbei) is a species of bird in the family Rhinocryptidae. It was described in 2020 as one of three new species in a species complex among Scytalopus birds inhabiting the Peruvian Andes. The South American Classification Committee of the American Ornithological Society accepted it as a new species in July 2020.

The Ampay tapaculo is a species of bird in the family Rhinocryptidae that the South American Classification Committee of the American Ornithological Society accepted as a new species in July 2020. It is endemic to Peru.
The Loja tapaculo is a species of bird in the family Rhinocryptidae that the South American Classification Committee of the American Ornithological Society (AOS) accepted as a new species in July 2020. It had been classified as a subspecies of paramo tapaculo. It is found in Ecuador and Peru.
