Clements World List

There are a number of different world bird lists available. The Clements Checklist of the Birds of the World is an established authority for world listing. The 6th edition was published in 2007 and, following the death of Jim Clements in 2005, is now being maintained by the Cornell Laboratory of Ornithology. Cornell are publishing regular updates to the list and BUBO Listing will endeavour to keep up with these updates. The latest updates incorporated to date are those published on 18 December 2009.

Not surprisingly, the taxonomic treatments of various species or subspecies differ between Clements and other authorities. If you are unclear about how any species you have seen relates to the species listed in Clements, then contact us and we will endeavour to help. Even better, why not buy the book through the BUBO Store by following the appropriate link below?

The BUBO Listing version of the Clements List is shown below. Note that the Clements authority may be available for entering BUBO Lists of smaller regions than the entire world. In such cases, the base-list available will be cut-down appropriately, based on the lists maintained by Avibase, the excellent website managed by Denis Lepage and hosted by Bird Studies Canada.
