originally followed the HBW and BirdLife International Illustrated Checklist of the Birds of the World'' that was published as two volumes in 2014 and 2016. The taxonomy has been updated regularly by
BirdLife International. This taxonomy underpins the
IUCN Red List of Threatened Species and a number of international conventions, such as the
Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) and the
Convention on Migratory Species (CMS). The Clements taxonomy underpins the
Birds of the World website, the
Merlin Bird ID app for
iOS and
Android devices, the
eBird online database of bird observations and the
Macaulay Library of photographs, videos and audio recordings. ==English names==
