Arapaçu-de-bico-torto, which loosely translates to crooked-beaked woodcreeper. This bird most closely resembles a Curve-Billed Scythebill (Campylorhamphus procurvoides), said Tom Schulenberg, an expert in neotropical birds and Peruvian species, from the Cornell Lab of Ornithology.

Rapazinho-estriado-do-oeste, a new member of the Bucconidae family. We're not sure which this bird looks more like: David Bowie circa 1973, or a muppet. Photo: Vitor de Q. Piacentini

The Chorozinho-do-aripuanã, a small, bluish bird, resembles the Black-capped Antwren (Herpsilochmus atricapillus), said ornithologist Tom Schulenberg. Photo: Fabio Schunck

Can-can-da-campina, a bird endangered by habitat loss that belongs to the Cyanocorax genus, and is most closely related to crows. It resembles the Azure-naped Jay (Cyanocorax heilprini), said ornithologist Tom Schulenberg. Photo: Luciano Moreira Lima

Bico-chato-do-sucunduri, the flat-beaked (or flat-nozzle, according to Google translate) sucunduri. It appears most similar to the Yellow-margined Flycatcher (Tolmomyias assimilis), said ornithologist Tom Schulenberg. Photo: Fabio Schunck

Poiaeiro-de-chicomendes, a small, greenish bird, most closely resembles the Mishana Tyrannulet (Zimmerius villarejoi), said ornithologist Tom Schulenberg. Photo: Fabio Schunck

The muppet-Bowie bird most closely resembles the Striolated Puffbird (Nystalus striolatus), said ornithologist Tom Schulenberg. It's in the Piciform order, and is the only one of the new species that doesn't belong to Passeriformes. Photo: Fabio Schunck

Another view of the crow-like bird, which lives in the boundary between field and forest. Scientists are worried the bird's habitat is disappearing too quickly for it to survive. Photo: Luciano Moreira Lima

The muppet-Bowie bird is a new member of the Bucconidae family, which nest in holes -- either in the ground, or in a termite mound. Photo: Vitor de Q. Piacentini
