Pitt Island Shag has been uplisted to Endangered in the 2005 IUCN Red List
Zoom In

During 2004-2005, the status of 150 species was actively reviewed and discussed in the Globally Threatened Bird discussion forums on BirdLife's website, resulting in the IUCN Red List category being revised for 99 of these species in April 2005 (see below). These revisions will be incorporated into the 2005 IUCN Red List when this is released in late 2005.

The table below gives the totals in each IUCN Red List category in 2000, 2004 and 2005. The relatively small net changes to the totals mask the fact that 226 species moved between categories in 2000-2004, and 99 species moved between categories in 2004-2005 (see links below). These include category revisions owing to improved knowledge and taxonomic changes, as well as genuine changes in status. Therefore, it is difficult to interpret the changes in absolute totals. Instead, it is better to examine trends in the Red List Index, which shows graphically the net changes to the overall projected extinction risk of the world’s birds from 1988 to 2004.

Species changing IUCN Red List category between 2004 and 2005

The table below lists all 99 species whose 2004 IUCN Red List category was revised in April 2005 for the 2005 IUCN Red List. An explanation of the category codes and 'Reason for change' terms follows the table. Of the 99 category changes, 14 resulted from a genuine improvement (5) or deterioration (9) in the status of species, 48 were a result of improved knowledge (of the status of species or the threats impacting them) and 37 resulted from taxonomic revisions (either recently published or recently evaluated/re-evaluated by BirdLife). Full explanations for the taxonomic changes are given in the Taxonomic notes field on the species factsheets, which are available through the datazone along with a full explanation of the standard taxonomic sources BirdLife uses.
