Updates: Candidates

This page is a working list of Proposed Splits/Lumps (PS/PL) and Newly Described Species (NEW) that are candidates for addition to or deletion from the IOC World List. Accepted Splits (AS) will be added to the World List. Others will be retained as active candidates or deleted (DEL) with the option of future reconsideration.

NOTE: Phil Gregory has reviewed taxonomic issues for the birds of New Guinea, Muruk 10:1 (in press, Aug. 2011).  Phil has graciously allowed us to make this work available through the IOC website.  GREGORY REVIEW PNG BIRDS.
