Whether they are “mere subspecies” or “phylogenetic species”, the omission of such forms from the ICBP (now BirdLife International) Red Data Book (RDB) was my personal decision, and I have long been sensitive to the type of charge contained in Hazevoet's paper (preceding pages). This decision, taken back in 1982, was based on the time, space and cost that would have been involved in the systematic review and inclusion of subspecies (RDBs being much fuller treatments than those in Birds to watch 2, the work criticized for the omission by Hazevoet), and on the fact that the future of the many “full” species needing urgent documentation and action consequently stood to be compromised.
