Species level
The 3 species in Dendrocolaptidae are now included in Furnariidae. Dohrn's Flycatcher moves from Muscicapidae (Old World Flycatchers) to Timaliidae (Babblers) and changes name to Dohrn's Thrush-Babbler. The 5 Euphonia and the 1 Chlorophonia species on stamp move from Thraupidae to Fringillidae. This move was presented on the Ibis website, but had not been implemented by me. Przevalski's Rosefinch has been removed from Emberizidae and placed in a family of it’s own, Urocynchramidae. Total number of familymoves for bird species on stamp is 11.

2 of our bird species on stamp are not listed as species in Clements 6. Black-backed Wagtail Motacilla lugens (China (Taiwan) 1991 Taiwan stream birds, Korea, North 1965 Korean birds) has been lumped and is now a subspecies to White Wagtail M alba. Indonesia’s recent Wattled Smoky Honeyeater Melipotes carolae is not included, probably because it has not yet been described in a scientific journal. I’ll include it as a personal update to my Clements 6 list. Grey Fantail Rhipidura fuliginosa becomes Grey Fantail Rhipidura albiscapa and New Zealand Fantail Rhipidura fuliginosa. I shall list Norfolk’s and Vanuatu’s grey fantails as Grey Fantail Rhipidura albiscapa and New Zealand’s fantails as New Zealand Fantail Rhipidura fuliginosa. Micronesia’s Oriental Cuckoo Cuculus saturatus should have been identified as Horsfield’s Cuckoo Cuculus horsfieldi. In Clements 6 this bird changes English and scientific name and becomes Oriental Cuckoo Cuculus optatus. This is the cuckoo on the Micronesia stamp. Cuculus saturatus, now called Himalayan Cuckoo, is no longer on stamp.
