Green toucanet

Green toucanets[1] are near-passerine birds from the genus Aulacorhynchus in the toucan family. They are native to Mexico, and Central and South America. All are found in humid forests and woodlands in highlands, but a few also occur in adjacent lowlands.[2] They are relatively small toucans, 30–44 centimetres (12–17 in) long, with colorful, mainly green, plumage.[2] They are typically seen in pairs or small groups, and sometimes follow mixed species flocks.[3]

Taxonomy and systematics

A major taxonomy review in 1974 resulted in 6 species in the genus Aulacorhynchus,[4] and this was adopted by virtually all later authorities.[2][5][6][7][8]

In 2001, it was suggested that A. prasinus, as traditionally defined, was a species complex that should be split into 7 different species based on preliminary morphological evidence.[9] This was to some extent supported by genetic evidence, which suggested that additional species should be recognized. As a result, A. griseigularis was split from in A. albivitta based on this early genetic evidence but these species are now lumped together again.[10][11]

Currently, there remains a considerable lack of consensus to support the IOC's latest taxonomy of Aulacorhynchus into eleven species.[12] Several authorities still maintain that the genus Aulacorhynchus has only 7 species and treat the remaining as subspecies.[7][8] The SACC has called for further genetic studies of this genus.[5]

gollark: Hmm, it's rust, so actually it would be fairly ironic, but also carbonated.
gollark: I MAY "unironically" implement my own zstd/sqlite/rustaceous archiver.
gollark: Yet the web standard people did brotli, due to bee.
gollark: I used that, but tar is actually bad.
gollark: My backups are currently done via inconsistent mixes of sqlar and rsync.
